The accessory structures of the integument include the (a) blood vessels, glands, muscles, and nerves, (b) tactile discs, lamellar corpuscles, and tactile corpuscles, (c) hair, skin, and nails, (d) hair follicles, nails, sebaceous glands, and sweat glands.

Verified step by step guidance

1. Step 1: Understand the term 'accessory structures of the integument'. These are structures associated with the skin that support its function.
2. Step 2: Review the options provided and identify which ones are directly associated with the skin.
3. Step 3: Consider the role of each option in relation to the skin. For example, hair follicles, nails, sebaceous glands, and sweat glands are all structures that are part of or extend from the skin.
4. Step 4: Eliminate options that do not fit the definition of accessory structures of the integument. For instance, blood vessels and nerves are part of the skin's structure but not accessory structures.
5. Step 5: Choose the option that best represents the accessory structures of the integument, focusing on those that are external or serve a supportive role to the skin's primary functions.

Key Concepts

Accessory Structures of the Integument

Accessory structures of the integument refer to the various components that support and enhance the function of the skin. These include hair follicles, nails, and glands such as sebaceous and sweat glands, which play crucial roles in thermoregulation, protection, and sensation.

Integumentary System

The integumentary system is the body's largest organ system, comprising the skin and its associated structures. It serves multiple functions, including protection against environmental hazards, regulation of body temperature, and sensory perception, making it vital for overall health.

Types of Glands

The integument contains various types of glands, primarily sebaceous and sweat glands. Sebaceous glands secrete oil to lubricate the skin and hair, while sweat glands help regulate body temperature through perspiration. Understanding these glands is essential for comprehending skin health and function.
