Anatomy & Physiology Endocrine #7

Question

Which hormone is stored and released by the intermediate-pituitary gland?

Answers

  1. Thyroid-stimulating hormone
    • Rationale:

      The thyroid stimulating hormone is secreted by the anterior, not intermediate-pituitary.

  2. Corticotropin-releasing hormone
    • Rationale:

      The corticotropin-releasing hormone is secreted by the hypothalamus, not the intermediate-pituitary.

  3. Melanocyte-stimulating hormone
    • Rationale:

      The melanocyte-releasing hormone is secreted by the intermediate-pituitary. The primary function of this hormone is controlling appetite, developing pigmentation, and protecting the skin from ultraviolet (UV) rays.

  4. Growth hormone-releasing hormone
    • Rationale:

      The growth hormone-releasing hormone is secreted by the hypothalamus, not the intermediate-pituitary.

Overview

The endocrine system is the collection of glands. These glands produce hormones that regulate many functions within the body.

Explanation

Learning Outcomes

Specific functions that are regulated by endocrine glands include, but are not limited to, growth and development, metabolism, mood, reproduction, sexual function, sleep, and tissue function. There are nine glands within the endocrine system. The pituitary gland is divided into three separate lobes. The intermediate-pituitary is responsible for the secretion of melanocyte-stimulating hormone.

Test Taking Tip

Consider the structure and function of the intermediate-pituitary gland to answer this question correctly.
