Neurone Organelle Functions Flashcards
1
Q
Dendrons and Dendrites
A
allow connections between neurones or to receptors
2
Q
Axon
A
extension of cytoplasm, carries nerve impulses away from the cell body
3
Q
Myelin Sheath
A
wraps around axon + carries nerve impulses away from the cell body
Provides electrical insulation
4
Q
Nodes of Ranvier
A
Gaps in myelin sheath that allow nerve impulses to jump along the axon
5
Q
Cell Body
A
Provides proteins for dendrites, axons and synapses that contain special organelles
6
Q
Nerve Endings
A
Branches to form connections (synapses) with other neurones
7
Q
Nucleus
A
Controls neurone’s activities
8
Q
Cell Membrane
A
Controls what goes in and out of the cell
9
Q
Cytoplasm
A
where chemical reaction happen
contains enzymes, fatty acids, amino acids to keep cell working
