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

Chapter2 Muscle function and physiology Introduction: Movement Control There has been much interest in and reference to stability of the spine over the last few decades. 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.

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.

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.

The global epidemiology of coronavirus disease 2019 (COVID-19) suggests a wide spectrum of clinical severity, ranging from asymptomatic to fatal. 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.

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.
