ANS
| Question | Answer |
|---|---|
| Neurons | Conduct impulses from one body part to another |
| Cell body | Concerned with metabolism and function of the cell |
| Dendrites | Extensions of cytoplasm from the cell body, conduct impulses towards cell body |
| Axon | Conducts impulses away from the cell body |
| Synaptic end bulbs | Bulb like structures at the end of the axon that hold synaptic vessicles |
| Synaptic vessicles | Contain neurotransmitters: Norepi, Ach, Dopamine, Serotonin |
| Mylein Sheath | Speeds up conducton down the axon, insulates the axon |
| Neurolemmocytes | makes up the sheath covering the PNS |
| Neurolemma | Outer layer of neurolemmocytes (contain schwaan cells) |
| Schwaan cells produce | nerve growth factor |
| CNS myleain sheath | Oligodendrocyte cells, Schwaan cells are not present therefore they do not regenerate |
| CNS is comprised of | Brain and spinal cord |
| Peripheral nerves are comprised of | Efferent and Afferent nerves |
| Efferent nerves comprised of | Somatic nervous system (voluntary) Autonomic nervous system (involuntary) |
| SNS neurotransmitter | Epi and Norepi |
| PNS neurotransmitter | Ach |
