Document Summary
Nervous system: comprised of central nervous system (spinal cord and brain). Signals sent from neurotransmitters from neuron to neuron. Peripheral nervous system: somatic system (voluntary. ex. walking), autonomic system (involuntary. Ex. heart is breathing)--parasympathetic (calms body down) and sympathetic (excited your body) Nervous system can directly transmit signals to other body parts through neurons or it can have an effect on hormones (can have an effect on the endocrine system). Nervous system connects brain spinal cord to the rest of the body; neuron to neuron transmission of signals through neurostansmitters. How to mobilize the body through the nervous system: sam and hpa. Sam: epinephrine and norepinephrine released as one pathway from nervous system. Sympathetic nervous system adrenal gland release epinephrine/norepinephrine. Hpa: hypothalamus leads to release of crh which goes to anterior pituitary which releases acth which goes to adrenal cortex which releases cortisol.
