Question

Nervous tissue forms nerves that vary in length. The flexibility of nerve length allows communication to occur between regions of the body that are very close to each other, or very far away from each other. One example of a very long nerve is the sciatic nerve, which runs from the spinal cord to the toes and is approximately one meter long. Which of the following is supported by the passage?

A. Only distant regions would communicate using nervous tissue
B. Only nearby regions would communicate using nervous tissue
C.Both distant and nearby regions would communicate using nervous tissue
D. Neither distant nor nearby body regions would communicate using nervous tissue

Answer 1

C.Both distant and nearby regions would communicate using nervous tissue

An impulse from nervous tissue must be transmitted to the brain to be perceived. A long nervous tissue will transmit everything in their path. The nerve is not only traveling to the toes but also branched to nearby tissue so it can capture any impulse.

Answer 2

The correct answer is C. It's very obvious from the passage that the nerves may reach the distant regions like the sciatic nerve that communicates between the spinal cord and the toes. The nerve is a tissue that is composed of different types of cells. mainly, the nerve contains the nerve bundles. Each nerve bundle consists of a group of axons of nerve cells grouped together in a sheath. The nerve tissue an artery and a vein for the blood supply. The nerve may reach 2 meters long in some cases and may have branches.
