Draw a diagram of a typical neuron, label its parts, and list the function of each labeled structure.

Figure 41-2 ​

The diagram and its labels should resemble Figure 41-2. The functions are as follows:
* dendrites: receive stimuli and generate a neural impulse
* cell body: receives signal from the dendrites
* axon: conducts neural impulses (often via branches called axon collaterals) away from the cell body
* myelin sheath: insulates axons (note: the myelin sheath is a membrane extension of other cell types-Schwann cells or oligodendrocytes)
* nodes of Ranvier: gaps between myelin sheaths
* synaptic terminals: release neurotransmitters into the synaptic cleft
