Basic Nervous System Anatomy

What does CNS and PNS stand for?
Central Nervous System
Peripheral Nervous System

What are the parts of the CNS?
Brain And Spinal Cord (controls thinking memory and behavior)(organs controlled by pns)

Describe something that you do on a regular basis that your PNS controls.
urination.

What are the two divisions of the autonomic nervous system and what does each control?
Sympathetic - (controls body in stressful situations)
Para-sympathetic (Brings body back to normal allows for rest and relaxation.)

What are the three main types of neurons? What is the function of each?
sensory neuron - Receive impulses from the body
motor neuron - neuron that is sent back to impulse to tell you how to react.
interneuron - transports impulses to the brain

What is the function of the axon of a nerve cell? The dendrite?
Neural impulses are sent from the axon and end up at the dendrite.
then synapse happens and it jumps to neuron.

What is a synapse?
conduction of an impulse from one neuron to another.

Sketch a neuron and label the axon and the dendrite.
