Cell Organization - Structural components Flashcards
1
Q
Structural components of a neuron
A
Soma, dendrites, axon, myeline sheath - nodes of ranvier, axon hillock, terminal ultipolar, bipolar neurons, motor, sensory, and interneurons
2
Q
Soma
A
cell body: contains the nucleus and much of machinery that operates cell
3
Q
Dendrites
A
Receive info from other neurons; can grow and form new connections
4
Q
Axon
A
Collaterals - telodendria
Can grow and form new connections
A nerve is composed of many axons surrounded by a tough, elastic connective membrane
5
Q
Myelin sheath
A
Nodes of ranvier
6
Q
Axon hillock
A
where action potential originates
7
Q
Terminal button
A
Secretes transmitter substance or NT - forms synapse with dendrites, soma or axons of other neurons
