Questions: Multiple Choice Question Which system only innervates one organ and a limited number of cells within that organ?

The answer is the first one (or A): the original text in the question...

Explanation for each option:

A. The answer is the first one (or A): the original text in the question...

• This option is not a valid answer as it simply repeats the instruction and does not provide any information about a specific system.

B. The autonomic nervous system

• This system innervates multiple organs and regulates involuntary functions such as heart rate, digestion, and respiratory rate. It is divided into the sympathetic and parasympathetic nervous systems, both of which affect a wide range of organs and tissues.

C. The somatic nervous system

• This system controls voluntary movements and innervates skeletal muscles throughout the body. It does not limit its innervation to a single organ or a limited number of cells within an organ.

D. The enteric nervous system

• This system is a part of the autonomic nervous system and specifically controls the gastrointestinal tract. While it is focused on one organ system, it still innervates a large number of cells and tissues within the digestive system.

Summary: None of the provided options accurately describe a system that innervates only one organ and a limited number of cells within that organ. Therefore, the question may be based on a misunderstanding or lack of clarity in the options provided.
