Neuro System

1. Function of Nervous System- responsible or it coordinates for controls or regulate all bodily activities.

2. Neurons- they carry messages to and from the brain + spinal cord. Functioning unit of the nervous system

3. Neurol -(support cells to the neuron support or protect neurons while producing cerebrospinal fluid (CSF)

4. S - SENSORY- emerge from the skin or sense organ

A - AFFERENT- NEURONS + CARRY IMPULSES "TOARD THE BRAIN + SPINAL CORD

M - MOTOR - action from the afferent

E - Efferent - carrying impulses "away" from the brain & spinal cord "toward" the muscles & glands

5. Acetycholine- nerve impulses transmission it spills into the synapse area + speeds the transmission of the impulse

6. myetin sheath - white, waxy, fatty material that protects or covered the axon.

-Increases that rate + transmission of impulses + protects + insulates the fibers.

7. Neurolemona (sp?) - outer covering of the myelin sheath made by (schwann cells_ that can only be found in peripheral nervous System (PNS)

8. Dopamine - affects motor function, it involved in gross subconscious movements of the skelitar muscles.

- Parkinsins desease ( decreases in dopamine levels & sufferes tremors.

9. serotonin - neurotransmitter - induses sleep, controls temperature

10. CNS - composed of brain + spinal cord. Responsiblefor
