locations and functions of parts of the neuron Flashcards
(11 cards)
1
Q
soma
A
- the body of a neuron
- processes and integrates the information from the dendrites
2
Q
dendrites
A
the sensory process of a neuron (receives information)
3
Q
axon
A
the elongated extension of a neuron that conducts an action potential
4
Q
nucleus
A
a cluster of neuron cell bodies located within the central nervous system (CNS)
5
Q
nucleolus
A
the dense region in the nucleus that is the site of RNA synthesis
6
Q
Neurofilament
A
specialized protein fibers found inside neurons that help support and maintain the shape and structure of the cell
7
Q
Nissl bodies
A
- clusters of RER and ribosomes found inside the soma and dendrites of neurons
- they are responsible for producing proteins
8
Q
axon hillock
A
the part of a neuron that connects the cell body to an axon
9
Q
axolemma
A
the plasma membrane of an axon
10
Q
telodendria
A
the fine branching extensions at the end of an axon in a neuron
11
Q
axon terminals
A
the enlarged end of each telodendria branch that forms a synapse with another cell
