THE NEURON Flashcards
1
Q
Cell body
A
- life support of the cell
* contains usual cell organelles
2
Q
Dendrite
A
Branched ends of cell body that receive impulses from other neurons/muscles/glands
3
Q
Axon
A
•carries impulses away from the cell body along myelin sheath and nodes of ranvier
4
Q
Axon terminal
A
Branched ends of the axon that connect to and carry impulses to other neurons/muscles/glands
5
Q
Myelin sheath
A
- fatty substance
- insulates nerve cell
- speeds up nerve impulse transmission
6
Q
Schwan cell
A
- produces myelin
* located within myelin sheath
7
Q
Nodes of ranvier
A
•uninsulated gaps along the axon
