Document Summary

Types of nerves: affront: feel/experience sensation efferent: moves body. Peripheral: goes to muscles, bones, organs, etc. subcategories: somatic: part of peripheral involved in muscles/sensory/motors autonomic: automatic . Regulated internal organs/glands, and our sensory abilites. Stress and strain: sympathetic nervous system is overly active. Evolutionary adaptation to get us out of danger (activates us to get out) Opens pupils > more light gets in, can respond better. Accelerate heart > more blood ow throughout body > run, ee, etc. Inhibits digestion & slows tomach/pancres (dont want to expend energy into these functions when u gotta run) Liver converts glycogen to glucose > allows us to use more energy to run and ee. Adrenal glands activated: ad-renal (on top of kidney) > release adrenaline and noradrenaline which travel thru blood to further activate > endocrine/hormonal system (chemical activation of body) Bladder relaxes > allows us to hold onto uid/urine, sphincter at bottom becomes tighter so u don"t piss urself.
