Answer 1

Accessory structures of the skin such as apocrine and eccrine sweat glands, hair papilla, external root sheath, nail body, and arrector pili muscle correspond to specific functions and locations in the skin anatomy.

Step-by-step explanation:

The accessory structures of the skin play various roles in protection, sensation, and homeostasis. Here are the names of the accessory structures that fit the descriptions provided:

1. Apocrine sweat glands: Sudoriferous glands located in axillary and genital areas; become active after puberty.
2. Hair papilla: Connective tissue projection provides blood supply for hair matrix.
3. Nail fold: Secures nail to digit.
4. External root sheath: Epithelial layer that surrounds hair root.
5. Nail body: Part of nail that is visible.
6. Free edge: Part of nail that extends beyond digit.
7. Hair bulb: Part of hair that contains the matrix.
8. Eccrine sweat glands: Sudoriferous glands that deposit sweat onto epidermal ridges causing fingerprints.
9. Hair shaft: Part of hair in epidermis and extending beyond skin surface.
10. Arrector pili muscle: Moves hair shaft perpendicular to skin; causes goose bumps.
11. Eponychium (cuticle): Thickened epithelial tissue at proximal end of nail body.
12. Lunula: Crescent-shaped area of nail body near cuticle.
13. Hair root: Part of hair within dermis.
14. Nail bed: Part of nail within skin.
15. Nail matrix: Part of nail deep to nail root that produces new cells, causing the nail to grow.
