Verified step by step guidance1
Understand the basic structure of a neuron, which typically includes the cell body (soma), dendrites, and axon.
Recognize that the myelin sheath is a protective covering that surrounds the axon of some neurons, aiding in the rapid transmission of electrical signals.
Identify that dendrites are branched extensions of the neuron that receive signals from other neurons.
Note that the axon is a long, slender projection that conducts electrical impulses away from the neuron's cell body.
Clarify that a sarcomere is not part of a neuron; it is the basic contractile unit of muscle fiber, found in muscle cells, not neurons.
