Observe the diagram of a neuron below:
1. Which part of the neuron receives signals from other neurons?
Axon
Dendrite
Cell body
Myelin sheath
2. What is the primary function of the myelin sheath?
To produce neurotransmitters
To speed up signal transmission
To provide structural support
To generate action potentials
3. The is the long, slender projection of a nerve cell that conducts electrical impulses away from the cell body.
4. Gaps in the myelin sheath along the axon are called the .
5. Neurotransmitters are chemical messengers that transmit signals across a synapse.
True
False
6. All neurons have a myelin sheath.
True
False
7. Briefly describe the process of synaptic transmission.
8. Explain the difference between a sensory neuron and a motor neuron.
