Question

Which of the following statements about nervous system communication is not correct?

A.
The nervous system uses electrical and chemical signals to communicate internally.
B.
The nervous system uses neurons to communicate internally.
C.
The nervous system uses glia cells to communicate internally.
D.
The nervous system uses endocrine glands to communicate internally.

Answer 1

The incorrect statement regarding nervous system communication is that the nervous system uses endocrine glands to communicate internally; this is a function of the endocrine system.

Step-by-step explanation:

The statement about nervous system communication that is not correct is:

D. The nervous system uses endocrine glands to communicate internally.

While the nervous system does utilize both electrical and chemical signals for communication through neurons, and glia cells provide support functions, it is the endocrine system that uses endocrine glands for widely dispersed chemical signaling through hormones in the bloodstream, not the nervous system. The nervous system's communication is generally much faster using neurons for immediate actions, whereas the endocrine system's hormonal signaling can take significantly longer, although there can be exceptions such as the quick release of adrenal hormones in a fight-or-flight response.

Answer 2

The answer is D. The nervous system does not use endocrine glands to communicate internally - endocrine glands are part of the endocrine system, not the nervous system. Whilst the endocrine glands do help communicate messages within the body through hormones, they do not interact with the nervous system in this way.
