The coiled tubular structures arising from the dermis that excrete sweat are the:

• A. sebaceous glands
• B. hair follicles
• C. lymph nodes
• D. sweat glands (sudoriferous glands)

Answer: (D)

Verified step by step guidance

1. Understand the question: The problem is asking about the structures in the dermis responsible for excreting sweat. This requires knowledge of skin anatomy and the functions of its components.
2. Review the options provided: (1) Sebaceous glands, (2) Hair follicles, (3) Lymph nodes, and (4) Sweat glands (sudoriferous glands). Each of these structures has a distinct function in the body.
3. Clarify the function of each option: Sebaceous glands secrete sebum (oil) to lubricate the skin and hair. Hair follicles are structures that produce hair. Lymph nodes are part of the immune system and filter lymphatic fluid. Sweat glands (sudoriferous glands) are responsible for producing and excreting sweat.
4. Identify the correct structure: Based on the function described in the question (excreting sweat), the correct answer is sweat glands (sudoriferous glands). These are coiled tubular structures located in the dermis.
5. Conclude: The coiled tubular structures in the dermis that excrete sweat are sweat glands (sudoriferous glands), as they are specifically designed for this function.
