Relative to neuron anatomy, match the descriptors to the appropriate anatomical term.
Relative to neuron anatomy, match the descriptors to the appropriate anatomical term.
- releases neurotransmitters
- conducts localized electrical currents toward the cell body/soma
- increases the speed of impulse transmission
- location of the nucleus
- conducts impulses away from the cell body/soma
- most are located and protected within the CNS
- short, tapering, "input" branched extensions from the cell body
- the neuronal process that is found in a nerve fiber
- formed by Schwann cells in the PNS
- clusters of ribosomes and rough endoplasmic reticulum
- most of these are found in the CNS where they are protected by the bones of the skull and vertebral column.
- Nodes of Ranvier are found between these structures
- Axon terminal
- Cell body
- Dendrites
- Myelin sheath
- Nissl bodies
- Axon
