Name the 3 functions of the nervous system

What is Sensation, Integration, Motor output

100

these provides support and protection of neurons, they are smaller than neurons and more numerous

What is Neuroglia

100

Found at the end of the axon

Axon terminals / synaptic end bulbs

100

These cover the brain and spinal cord for protection

meninges

31

200

Special chemicals that transmit info from one neuron to another is called what?

neurotransmitters

300

Two subdivisions of the Autonomic Nervous System 

What is Parasympathetic Division- "rest and digest" and Sympathetic "Fight of Flight"

300

three parts of a neuron

1- cell body (soma) 2- dendrites 3- axon 4- myelin sheaths 5- axon terminals 6- nodes of ranvier

300

What are the 4 main lobes?

1. Frontal

2. Parietal

3. Temporal

4. Occipital
