The Nervous System: Anatomy Review 1. Neurons communicate with other neurons and stimulate both ___________ and ______________. 2. Match the following parts of the neuron and their function: Dendrites - conductive region; generates an action potential Soma (cell body) - input area; receives signals from other neurons Axon - input area; main nutritional and metabolic area 3. Signals from other neurons are received at junctions called ________________, located primarily on the ________________ and __________________, the receptive and integrative region of the neuron. 4. The area where the axon emerges from the soma is called the ____________ ___________. This is also the area where the outgoing signal, called a/an _____________ _____________ is generated. 5.

Unformatted text preview: 6. What support cell forms the myelin sheath? __________________ Myelin is found around which part of the neuron? ______________ The tightly wound cell membrane around the axon forms the myelin sheath and acts as ________________. 7. The gaps between the Schwann cells, called the __________________________, are essential for the conduction of the action potential. 8. The most common central nervous system neuron, which was examined in this exercise, is called a/an _______________________ neuron. In the quiz section, you labeled a/an _____________________ neuron, which is found in the peripheral nervous system. 9. Neurons have (only one or many) axon/axons. Axons are (never or frequently) branched. Dendrites have (only one or many) branch/branches....
