Question

Select the best description of axon: a. stored in synaptic vesicles b. accumulates as yellow-brown granules as the cell ages c. contains a nucleus surrounded by cytoplasm receiving or input portion of a neuron d. carries nerve impulses toward another neuron, a muscle fiber, or a gland cell

Answer 1

Answer:

d. carries nerve impulses toward another neuron, a muscle fiber, or a gland cell

Explanation:

An axon is a fiber of the nerves that transmits nerve impulses( electrical signals) away from a cell body and towards another neuron, muscle fiber or gland cell.

We have two types of axons in the body.

a. Myelinated axons

b. Unmyelinated axons.

The difference between Myelinated axons and Unmyelinated axons is that the Myelinated axons has an external covering or insulation which is called the myelin sheath.

The myelinated axons are very numerous and mush faster than the unmyelinated axon.
