MANOJ SHARMA UCMS & GTB HOSPITAL The term anatomy derives from the ancient Greek meaning to dissect. As in veterinary anatomy human anatomy is subdivided into macroscopic (or gross) and microscopic anatomy. Macroscopic anatomy describes structures, organs, muscles, bones etc. which are visible to the naked eye, that is macroscopic Human physiology is the science of the mechanical. The physiology of balance: vestibular function. The vestibular system is the sensory apparatus of the inner ear that helps the body maintain its postural equilibrium.The information furnished by the vestibular system is also essential for coordinating the position of the head and the movement of the eyes. There are two sets of end organs in the inner ear, or labyrinth: the semicircular canals. Rotation is movement of a bone around a longitudinal axis; it is a common movement of ball-and-socket joints. Abduction. Abduction is moving the limb away from the midline, or median plane, of the body. Adduction. Adduction is the opposite of abduction, so it is the movement of a limb toward the body midline. Circumduction

. One of the first texts to explore therapeutic exercise for spinal segmental stabilisation in low back pain was published in 1998 (Richardson et al 1998). These authors referred to Panjabi' Physiology studies the function of each structure, individually and in combination with other structures. Anatomy and physiology always work together. As we examine each part of the body, always consider both its structure and its function. The study of anatomy is divided into 2 major fields: 1 Digestion is the process of mechanically and enzymatically breaking down food into substances for absorption into the bloodstream. The food contains three macronutrients that require digestion before they can be absorbed: fats, carbohydrates, and proteins. Through the process of digestion, these macronutrients are broken down into molecules that can traverse the intestinal epithelium and enter. Movements of the jaw, hyoid and tongue (A) or soft palate (B) over time. Vertical positions of (A) the anterior tongue marker (ATM), lower jaw and hyoid bone and (B) soft palate, lower jaw and hyoid bone, each in a complete feeding sequence. Movement towards the top of the figure is upwards The cardiovascular system provides blood supply throughout the body. By responding to various stimuli, it can control the velocity and amount of blood carried through the vessels. The cardiovascular system consists of the heart, arteries, veins, and capillaries. The heart and vessels work together intricately to provide adequate blood flow to all parts of the body
Osmosis: Movement of water across a semi-permeable membrane due to differences in solute concentrations Guyton & Hall (Textbook of Medical Physiology, 12th ed.) - Figure 4.10 (mOsm / L) H 2 O Osmotic Pressure: The amount of pressure necessary to stop osmosis Pressure difference driving force for osmotic water flo Physiology of the Digestive System. Specifically, the digestive system takes in food (ingests it), breaks it down physically and chemically into nutrient molecules (digests it), and absorbs the nutrients into the bloodstream, then, it rids the body of indigestible remains (defecates). Mass movements. Mass movements are long, slow-moving. Simultaneously with downward movement of the diaphragm, the muscles of the abdominal walls are vigorously contracted, squeezing the stomach and thus elevating intragastric pressure. With the pylorus closed and the esophagus relatively open, the route of exit is clear. but helps to explain much of the physiology and pharmacology of vomition The gastrointestinal (GI) tract is the body's organ system responsible for digestion, absorption, and excretion of matter vital for energy expenditure and compatibility with life. It utilizes a multitude of organs to achieve this including the mouth, esophagus, stomach, small and large intestines, rectum, liver, biliary tract, pancreas, and glands that work together via complex mechanisms. Stages of labor Stage 1: Commences with the onset of labour and terminates when the cervix has reached full dilatation and membranes ruptured (lasts 8-24 hours). Stage2: Stage of expulsion begins at full cervical dilatation and ends with expulsion of the fetus (lasts 1-30 minutes)

The colon comprises of several parts: the ascending colon, the transverse colon, the descending colon and the sigmoid colon. The organ is around 4.5 feet long and approximately 2.5 inches wide. It is a sort of a tube made of muscles, connective tissue, blood vessels, nerves and lymphatic tissue Overview. The gastrointestinal (GI) tract, also known as the alimentary canal, commences at the buccal cavity of the mouth and terminates at the anus.It can be divided into an upper GI tract (consisting of mouth, pharynx, esophagus and stomach) and a lower GI tract (small and large intestines). The three primary functions of the GI tract are the ingestion of food and water, the digestion of. ADVERTISEMENTS: The following types of movements are found in the human small intestine: 1. Rhythmic segmentation or Ludwig's pendulum 2. Peristalsis. Type # 1. Rhythmic Segmentation: Nature: These are rings of contraction occurring at regular space of intervals in which a portion of the intestine is divided into segments. The contraction is followed by relaxation. [ Plant viruses spread from the initially infected cells to the rest of the plant in several distinct stages. First, the virus (in the form of virions or nucleic acid protein complexes) moves intracellularly from the sites of replication to plasmodesmata (PD, plant-specific intercellular membranous channels), the virus then transverses the PD to spread intercellularly (cell-to-cell movement)

Bucket-handle is a movement of ribs that results in change in transverse diameter of the thorax. Pump-handle is a movement of ribs that results in change in. Movement is smoothed and coordinated by the medial and intermediate portions of the cerebellum (spinocerebellum) and its connections. The basal ganglia and the lateral portions of the cerebellum (cerebrocerebellum) are part of a feedback circuit to the premotor and motor cortex that is concerned with planning and organizing voluntary movement
Skeletal System Physiology. The primary functions of the skeletal system include movement, support, protection production of blood cells, storage of minerals and endocrine regulation. Support. The primary function of the skeletal system is to provide a solid framework to support and safeguard the human body and its organs The Liver. The human liver is both the largest internal organ (the skin being the largest organ overall) and the largest gland in the human body. It is a soft, pinkish-brown, triangular organ normally weighing 1.44-1.66 kg (3.2-3.7 lb). The liver has a wide range of functions including detoxification, protein synthesis, and the production. Physiology of Spermatogenesis . Seminiferous Tubule: Micrograph showing seminiferous tubule with maturing sperm. Maturation takes place under the influence of testosterone, which removes the remaining unnecessary cytoplasm and organelles. The excess cytoplasm, known as residual bodies, is phagocytosed by surrounding Sertoli cells in the testes Baroreceptors are a type of mechanoreceptors allowing for relaying information derived from blood pressure within the autonomic nervous system. Information is then passed in rapid sequence to alter the total peripheral resistance and cardiac output, maintaining blood pressure within a preset, normalized range. There are two types of baroreceptors: high-pressure arterial baroreceptors and low.

Bradykinesia can be defined as slow movement, and is often characterized by difficulty initiating, maintaining, or synchronizing (voluntary) movement. Among the most challenging aspects of bradykinesia is the fact that all striated muscles are eventually affected. Thus, as the disease progresses, those PD experience impeded mastication. Exercise stimulates the sympathetic nervous system and will induce an integrated response from the body. This response works to maintain an appropriate level of homeostasis for the increased demand in physical, metabolic, respiratory, and cardiovascular efforts. Exercise challenges many human physiological systems that need to adapt in order to.

. Although the clinical and laboratory characteristics of COVID-19 patients have been well characterized, the pathophysiological mechanisms underlying disease severity and progression remain unclear Peristalsis, involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but occasionally in other hollow tubes of the body, that occur in progressive wavelike contractions. Peristaltic waves occur in the esophagus, stomach, and intestines. The waves can be short, local reflexes or long, continuous contractions that travel the whole length of the organ. Physiological psychology is a subdivision of behavioral neuroscience (biological psychology) that studies the neural mechanisms of perception and behavior through direct manipulation of the brains of nonhuman animal subjects in controlled experiments. This field of psychology takes an empirical and practical approach when studying the brain and human behavior
15.3 Hearing Audition (Hearing) Hearing, or audition, is the transduction of sound waves into a neural signal that is made possible by the structures of the ear (Figure 15.3.1).The large, fleshy structure on the lateral aspect of the head is known as the auricle.Some sources will also refer to this structure as the pinna, though that term is more appropriate for a structure that can be moved. Fetal Physiology - Respiration Gross breathing movements at 11 weeks Rapid and irregular - associated with REM (rapid eye movements) Isolated slow movements - gasps Apnea - periods of no breathing Maternal eating Æincreases breathing rate Maternal smoking Ædecreases breathing rate Function of fetal breathing: Stimulates growth of the lung Net fluid movement will be in the direction of the lower pressure. Osmosis is the movement of solvent (water) across a membrane that is impermeable to a solute in the solution. This creates a pressure, osmotic pressure, which will exist until the solute concentration is the same on both sides of a semipermeable membrane the aquaporin family of water channels consists of 10 proteins cloned from mammals and many more from amphibians, plants, yeast, bacteria, and various lower organisms. There has been considerable interest in the biology of aquaporins (AQPs) with more than 500 studies published over the past 5 years on aquaporin cloning, genetics, tissue localization, developmental and regulated expression. • The nerve impulse causes a movement of ions across the cell membrane of the nerve cell.

Tubular secretion 54 Anatomy and physiology of the ear and hearing Figure 2.1. The pinna and external auditory canal form the outer ear, which is separated from the middle ear by the tympanic membrane. The middle ear houses three ossicles, the malleus, incus and stapes and is connected to the back of the nose by the Eustachian tube The Diaphragm is a dome-shaped musculotendinous sheet separating the thoracic and abdominal cavities. It is convex on its cranial surface. In the neutral position between full inspiration and full expiration, the most cranial part of the diaphragm is in line with the 6th rib The skeleton is the structural framework of bones which gives shape and support to the body.

The homeostatic regulation of fluid intake by the brain is multifactorial. Osmotic, ionic, hormonal, and nervous signals converge on, and are integrated within, the central nervous system. Consequentially, neural circuitry (yet to be identified) that subserves the conscious perception of thirst may become activated Human ear - Human ear - The physiology of hearing: Hearing is the process by which the ear transforms sound vibrations in the external environment into nerve impulses that are conveyed to the brain, where they are interpreted as sounds. Sounds are produced when vibrating objects, such as the plucked string of a guitar, produce pressure pulses of vibrating air molecules, better known as sound. A motor unit, the functional unit of muscle contraction, is a single motor nerve and the associated muscle fibers that are innervated upon stimulation from the nerve. A collection of motor units is referred to as a motor pool. The number of muscle fibers within each unit can vary within a particular muscle, which impacts precision and force. Basal metabolic studies carried out in the 1920s and 1930s by Sandiford and Wheeler 8 and Rowe and Boyd 9 demonstrated that pregnancy is characterized by increased metabolic activity as measured by the basal metabolic rate. In these studies, done on a small group of women throughout gestation, they found that the basal metabolic rate increased by approximately 20% as the pregnancy approached term focal length, colour vision, movements of eyes, visual cerebral cortex Ear: structure and function of outer, middle and inner ear, organ of Corti, auditory cerebral cortex 3 Understand the physiology of the nervous system Central nervous system: brain, spinal cord Peripheral nervous system: cranial nerves, spinal nerve
In this article we will discuss about the Flow of Source and Sink in Phloem Translocation.

Movement patterns depend on consistency of material swallowed; Liquid Bolus has a certain degree of cohesiveness that may be maintained as bolus is held between tongue and anterior hard palate. Lip Closure; Facial tone helps with labial seal. Rotary, lateral jaw movement The orbit is the bony eye socket of the skull. The orbit is formed by the cheekbone, the forehead, the temple, and the side of the nose. The eye is cushioned within the orbit by pads of fat. In addition to the eyeball itself, the orbit contains the muscles that move the eye, blood vessels, and nerves Boyle's Law describes the relationship between the pressure (P) and the volume (V) of a gas. The law states that if the volume increases, then the pressure must decrease (or vice versa). This relationship is often written algebraically as PV = constant, or P 1 V 1 = P 2 V 2.Both equations state that the product of the pressure and volume remains the same

The main function of the respiratory system is to draw air into the lungs to allow the exchange of gases with blood circulating to the lungs. This article has been updated. The evidence in this article is no longer current Nurses need to understand the anatomy and physiology of normal breathing to measure respiratory rate and interpret findings. The second in our five-part series on respiratory rate describes the process of breathing and how it is affected by ill health. Citation: Hartley J (2018) Respiratory rate 2: anatomy and physiology of breathing Most of our information about the anatomy and physiology of pain-transmission pathways in the central nervous system is derived from animal studies. However, it is known that in humans, lesions of this anterolateral pathway permanently impairs pain sensation and that electrical stimulation of it produces pain (Cassinari and Pagni, 1969; White.
Several movements may be performed by synovial joints. Abduction is the movement away from the midline of the body. Adduction is the movement toward the middle line of the body. Extension is the straightening of limbs (increase in angle) at a joint. Flexion is bending the limbs (reduction of angle) at a joint Physiology of Circulation Roles of Capillaries. In addition to forming the connection between the arteries and veins, capillaries have a vital role in the exchange of gases, nutrients, and metabolic waste products between the blood and the tissue cells.
