Part 1 Introduction: the general and cellular basis of medical physiology. Part 2 Physiology of nerve and muscle cells: excitable tissue - nerve; excitable tissue - muscle; synaptic and junctional transmission; initiation of impulses in sense organs. Part 3 Functions of the nervous system: reflexes; cutaneous, deep and visceral sensation; vision; hearing and equilibrium; smell and taste; arousal mechanisms, sleep and the electrical activity of the brain; control of posture and movement; autonomic nervous system; central regulation of visceral function; neural basis of instinctual behaviour and emotions; higher functions of the nervous system - conditioned reflexes, learning and related phenomena. Part 4 Endocrinology, metabolism and reproductive function: energy balance, metabolism and nutrition; the thyroid gland; endocrine functions of the pancreas and regulation of carbohydrate metabolism; the adrenal medulla and adrenal cortex; hormonal control of calcium metabolism and the physiology of the bone; the pituitary gland; the gonads - development and function of the reproductive system; endocrine functions of the kidneys, heart and pineal gland. Part 5 Gastrointestinal function: digestion and absorption. Part 6 Circulation: circulating body fluids; origin of the heartbeat and the electrical activity of the heart; the heart as a pump; dynamics of blood and lymph flow; cardiovascular regulatory mechanisms; circulation through special regions; cardiovascular homeostasis in health and disease. Part 7 Respiration: pulmonary function; gas transport between the lungs and the tissues; regulation of respiration; respiration adjustments in health and disease. Part 8 Formation and excretion of urine: renal function and micturition; regulation of extracellular fluid composition and volume; appendices.
