100
What structures make up the PNS?
12 Cranial nerves and the 31 pairs of spinal nerves
200
Describe the function of dendrites in a neuron.
Branching extensions of the Neuron that act like the ears and receive impulses and send them to the cell body.

What neuron carries info to and from sensory system to the CNS?
Afferent (Sensory) Neurons
200
Explain the importance of the cerebellum
Coordinates musculoskeletal function and movements
200
What is the function of the CSF in your skull?
To cradle and cushion the brain

What is the difference between the Somatic and autonomic nervous system
Somatic- Is voluntary control that you can consciously control.
Autonomic- Processes involuntary physiological functions
300

What health concern is this
Spina Bifida
400
Describe the function of the axon.
Conducts nerve impulses away from the cell body and acts like the mouth and talks to the other neurons
400
What Neuron connects afferent and efferent neurons?
Interneurons

What is the difference between the sympathetic and parasympathetic nervous system
Sympathetic- fight or flight response (act in dangerous or stressful situations)
Parasympathetic- Operates to keep the body in homeostasis
