Question

Which of the following are functions of the nervous system? Check all that apply.

The nervous system processes information from receptors that detect changes in the environment.

The nervous system secretes hormones that help specific groups of cells perform specific functions.

The nervous system coordinates the systems of the body.

The nervous system sends out appropriate responses to react to changes in the environment.

The nervous system regulates growth, development, and reproduction.

The nervous system maintains homeostasis.

Answer 1

Check the following as functions of the nervous system:

- The nervous system processes information from receptors that detect changes in the environment. — Yes (sensory/integrative function)
- The nervous system coordinates the systems of the body. — Yes
- The nervous system sends out appropriate responses to react to changes in the environment. — Yes (motor/output function)
- The nervous system maintains homeostasis. — Yes (works with endocrine system to regulate body conditions)

Do not check:

- The nervous system secretes hormones that help specific groups of cells perform specific functions. — No (that is primarily the endocrine system; the nervous system does release a few neurohormones, e.g. ADH/oxytocin, but hormone secretion is mainly an endocrine function)
- The nervous system regulates growth, development, and reproduction. — No (these are primarily regulated by the endocrine system, though the nervous system influences them via neuroendocrine control)
