Briefly explain the function of the neuron cell body, dendrites, axon, myelin sheath, and end bulbs. Draw a diagram showing the structures

What will be an ideal response?

The cell body (or soma) is a relatively large, egg-shaped structure that provides fuel, manufactures chemicals, and maintains the entire neuron in working order.

Dendrites are branchlike extensions that arise from the cell body; they receive signals from other neurons, muscles, or sense organs and pass these signals to the cell body.

The axon is a single threadlike structure that extends from, and carries signals away from, the cell body to neighboring neurons, organs, or muscles.

The myelin sheath looks like separate tubelike segments composed of fatty material that wraps around and insulates an axon. The myelin sheath prevents interference from electrical signals generated in adjacent axons.

End bulbs or terminal bulbs look like tiny bubbles that are located at the extreme ends of the axon's branches. Each end bulb is like a miniature container that stores chemicals called neurotransmitters, which are used to communicate with neighboring cells.
