Anatomy & Physiology Integumentary #1

Question

Which gland is a structure of the integumentary system?

Answers

  1. Pineal
    • Rationale:

      The pineal gland is a part of the endocrine, not integumentary system. This gland produces a hormone called melatonin, which regulates sleep-wake cycles and reproductive hormones.

  2. Thyroid
    • Rationale:

      The thyroid gland is a part of the endocrine, not integumentary system. This gland releases hormones that control the body’s metabolism.

  3. Adrenal
    • Rationale:

      The adrenal glands are part of the endocrine, not integumentary system. These glands produce hormones that regulate blood pressure, the immune system, metabolism, and stress responses.

  4. Sebaceous
    • Rationale:

      The sebaceous glands are a structure of the integumentary system. Sebaceous glands not only lubricate the skin but moisturize it as well.

Overview

The integumentary system contains two types of exocrine glands, the sebaceous glands and the sweat glands. Sebaceous glands are found throughout the skin with the exception of the palms of the hands and the soles of the feet.

Explanation

Learning Outcomes

The integumentary system consists of exocrine glands (e.g., sebaceous, sweat), hair, nails (e.g., fingernails, toenails) and skin. The sebaceous glands produce and secrete sebum. Sebum lubricates the skin to protect it from injury. In addition, sebum makes the skin impenetrable to moisture.

Test Taking Tip

Eliminate wrong answers. The integumentary system contains only exocrine glands; therefore, ask yourself if each answer choice is an endocrine gland or an exocrine gland.
