An axon is a A) neuron's cell body. B) cluster of fibers at one end of a neuron. C) support cell in the nervous system. D) long, slim, tube-like structure extending from a neuron.

D) long, slim, tube-like structure extending from a neuron.

Explanation:

A neuron is a specialized cell which plays an important role in transmitting nerve signal or nerve impulse to other nerve cells. Neurons are made up of three parts mainly dendrites, cell body, axons.

Dendrite accepts the signal from another neuron, axon is long, thin and slender nerve cell projection that transfers electric impulse from the cell body towards axon terminal. Then from the axon terminal, the nerve impulse is released to another neuron. Therefore the correct answer is D.

1: the largest region of the brain is the:

  cerebrum

2. the term "psychology" literally means:

the process or procedure of the science or study of the mind.

3. the area of the brain responsible for respiration, heart rate, and smooth muscle control of our blood vessels is t

medulla oblongata

4. the structure that conducts nerve impulses to and from the brain and serves as a reflex center for some sensory information without input from the brain is the:

spinal cord

5. the three-layered membrane that covers the brain and spinal cord and literally means membrane is called the:

meninges

6. the cord-like (string-like) structures that carry bio-electrical impulses from one part of the body to another are called

nerves

7. a group of nerve cell bodies that are found outside of the spinal cord and brain are referred to as:

ganglions or ganglia (pl.) “literal meaning knot”

8. the term that means spinal cord inflammation is:

myel/itis
