Motor Neurones Flashcards
1
Q
Schwann Cell
A
Surrounds axon and provides a layer of myelin which electrically isolates the neurone
2
Q
Axon
A
Carries nerve impulse from cell body to axon terminals
3
Q
Cell Body
A
Contains the neurone nucleus
4
Q
Myelin Sheath
A
Layer of fatty tissues composed of Schwann cells
5
Q
Dendrites
A
Extensions from the cell body that receive nerve impulses
6
Q
Synaptic Bulbs
A
Swellings at the end of terminal axons, produce neurotransmitter
7
Q
Nodes of Ranvier
A
Gaps in the myelin sheath that allows nerve impulses to be conducted quickly
