Document Summary
4 lectures: learning and mem, language, ans + hypothalamus, emotion, motivation, addiction. Vta: electroconvulsive therapy prefrontal cortex parietal-temporal-occipital cortex left/right hemisphere. Homeostasis: cornerstone of physiology: anatomy + phgy of ans, ens, nst, autonomic reflexes, nt + receptors, coordination of ans function, hypothalamus functions and mechs, focus on its role in endocrine control. Hypothalamus regulates/integrates info from: ans: short term, rapid control, sensory + motor, innervates visceral tissues and organs, classified as: Autonomous, like a lil brain for ur intestine. Allows for gut motility, secretion of gut hormones: motivation/behaviour systems, we don"t know much, endocrine systems (pituitary): long term, hormonal secretion control. Blood pressure, electrolyte balance, circadian rhythms, temperature, metabolism, Motor neurons (ventral spinal cord/brain stem) skeletal muscle. Cns preganglion fibre autonomic ganglia postganglionic fibre (ans motor neurons) smooth muscle, cardiac muscle, or gland cells. Stimulate = minimize gap, allow for more spikes. Spinal cord sympathetic paravertebral chain ganglia target organs.
