Question

Which structure of the skin contains sweat gland coils which are important for the regulation of body temperature?

Answers

  1. Dermis
    • Rationale:

      The dermis is the middle layer of the skin. While the sweat gland runs through the dermis, the coiled sweat glands do not originate in this layer of the skin.

  2. Epidermis
    • Rationale:

      The epidermis is the outermost layer of the skin. Sweat pores, not the coiled sweat glands, are located in this layer of the skin.

  3. Hair follicles
    • Rationale:

      While hair follicles are a structure located in the skin, they do not play a role in temperature regulation.

  4. Subcutaneous tissue
    • Rationale:

      The sweat gland coils originate in the subcutaneous tissue or the hypodermis. Sweat glands play an essential role in temperature regulation.

Overview

Sweat glands produce perspiration which function to regulate body temperature.

Explanation

Learning Outcomes

Sweat gland coils originate in the subcutaneous tissue of the skin. Another term for this layer of the skin is the hypodermis. While the sweat gland coil originates in the innermost layer of the skin, the gland travels through the dermis and ends at the epidermis at the sweat pore. The sweat glands play an essential role in temperature regulation.

Test Taking Tip

Consider where the sweat gland coils originate to answer this question correctly.
