Anatomy & Physiology Endocrine #12

Question

Which hormone secreted by the hypothalamus impacts both ovarian and testicular function within the reproductive system?

Answers

  1. Antidiuretic hormone
    • Rationale:

      The antidiuretic hormone serves to maintain fluid homeostasis within the body; therefore, it does not impact both ovarian and testicular function within the reproductive system

  2. Vasopressin hormone
    • Rationale:

      Vasopressin is another term used for the antidiuretic hormone that is secreted by the hypothalamus which serves to maintain fluid homeostasis within the body; therefore, it does not impact both ovarian and testicular function within the reproductive system.

  3. Prolactin releasing hormone
    • Rationale:

      Prolactin releasing hormone plays a role in the production of human milk; however, it does not impact both ovarian and testicular function within the reproductive system.

  4. Gonadotropin releasing hormone
    • Rationale:

      Gonadotropin releasing hormone stimulates the pituitary gland to produce and secrete both luteinizing hormone and follicle stimulating hormone which are essential to the function of the ovaries and testicles within the reproductive system.

Overview

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

Explanation

Learning Outcomes

The hypothalamus is considered a master gland for the endocrine system. The hypothalamus secretes several hormones, including releasing hormones. While all of these hormones are secreted by the hypothalamus, it is the gonadotropin releasing hormone that impacts both ovarian and testicular function within the reproductive system.

Test Taking Tip

Think about the function of each hormone to answer this question correctly.
