| Question |
Answer |
| Dendrites |
Recieves information from other cells. Has tree like branches and if damaged will try to regrow. |
| Cell Body |
Thickest part of the cell and contains the nucules |
| Axon |
Tail like structure that carries nerve flow away from the cell body |
| Myelin |
Covers and protects the Axon and speeds up nerve flow down the axon. Made of Glial cells (fat cells) |
| Synapse |
Microscopic gap between cells where Neurotransmitters cross over |
| Receptors |
Recieving port on the next cell that recieves the Neurotransmitters |
| Neurotransmitters |
Chemical messangers of the brain. ( 50 identified ) |
| Cells At Rest |
Resting Potential |
| When A Cell Fires Is Known As |
Action Potential |
| All Or None Principle means |
Moves all the way down once fired. |
| "Ranvier" founded |
Founded the nodes. He saw the Sheath of the axon had little nodes in it. The nodes fire like spark plugs thus keeping the flow moving. |
| Lock And Key |
Nuerotransmitters blow out a gell to cross the synapse gap to the receptor cell. The neurotransmitter must fit the receptor site. |
| Enzymes |
Clean the Synapse gap |
| Hind Brain |
The Brain Stem. Oldest part of the brain. Medulla,Pons,Cerebellum |
| Nervous System (left) |
Central Nervous system = Has central role in life.or midline axis of the body. Includes Brain and Spinal Cord. |
| Nervous System (right) |
Peripheral = general "Nonspecific" out of spine. Includes-Somatic Nervous System. Autonomic Nervous System. Sympathetic Nervous System. Parasympathetic Nervous System. |
