1. Chapter 13

2. Nervous System Central: Peripheral: Brain and spinal chord
Cranial, and spinal nerves, ganglia

3. Autonomic System Maintains homeostasis Part of peripheral 2 parts
Sympathetic
Provides energy, and stress response “fight or flight”
Parasympathetic
Returns body to normal after stress, maintains normal body function

4. Neuron Types Sensory: Associative: Motor:
Carry sensory impulses towards CNS
Associative:
Carry info from one neuron to another
Motor:
Carry impulses away from CNS

5. Neuron Anatomy

6. Brain Anatomy

7. Cranial Nerves
Olfactory, optic, oculomotor, trochlear, trigeminal, abducent, facial, acoustic, glossopharyngeal, vagus, Accessory, hypoglossal

8. Spinal Chord

9. Common Ailments Ataxia: no coordination
Concussion: shaking of the brain -> leads to further injury
Hemiplegia: paralysis of one side
Macro/Micro-cephlagy: too large, too small skull
Meningitis: inflammation of the meninges (brain)

10. Common Procedures
Anesthesia: substance given to prevent pain. Without pain
Neurectomy: removal of nerves
Neuroplasty: surgical repair of a nerve
“Tap”- removal of fluid for study and culture
Pupillary light reflex: response of pupil to bright light source: shows neuro damage

11. Activities Chapter Review
Depict a neuron: Label the parts and what they do
Explain how a message is carried to the brain from a limb
What are the levels of consciousness? Define each. Give one example of a disease or “problem” that would cause each
Copy figure 13-1 for your notes. Explain what is happening/ what it depicts
