Document Summary

1010b lecture notes november 24th, 2015: know the divisions of the nervous system and their primary functions, central nervous system. Made up of brain and spinal cord: peripheral nervous system. Anything outside the brain and spinal cord is part of the peripheral nervous stem. Autonomic: controls involuntary things like organs: 2 branches of autonomic, 1) sympathetic kicks in when there is an emergency. Prepares the body when it needs to respond quickly: 2) parasympathetic to maintain body balance (homeostasis). Activated in response to the sympathetic branch activation to calm body down back to a steady state. Resting potential when neurons us at rest. When it is not activated by any neurons arou(cid:374)d it. Like a (cid:271)atter(cid:455) that"s (cid:374)ot i(cid:374) use (cid:271)ut stori(cid:374)g e(cid:374)erg(cid:455). Action potential when a resting neuron is stimulated by another neuron and the threshold is exceeded a surge of electrical energy moves down the axon.
