Integumentary System
Across
- 3. Covers and protects the dorsal surfaces of the distal bones of the fingers and toes
- 5. Connective tissue layer beneath the epidermis
- 6. Secrete sebum (oil) into the hair follicles where the hair shafts pass through the dermis. Prevents drying of skin.
- 8. structure with outer and inner root sheaths extending from the epidermal surface into the dermis and from which new hair develops.
- 10. A pigment that gives the skin its color
- 12. the less numerous type of sweat gland; produces a secretion containing water, salts, proteins, and fatty acids.
- 13. a primary tissure; form and function vary extensively. Functions include support, storage, and protection
- 16. a primary tissue that covers the body surface, lines its internal cavities, and forms glands
- 19. The crescent-shaped area at the base of the human fingernail.
- 20. dense irregular connective tissues making up approx. 80% of dermis
Down
- 1. Hardened keratin plate covering the nail bed
- 2. Anchors the epidermis to the dermis
- 4. Components: skin, hair, fingernails, toenails, sweat glands, oil gland
- 7. A fiber protein that is the principal component of hair, skin, and nails
- 9. Absence of pigment in the skin, hair, and eyes
- 11. Portion of the living skin that supports the nail plate as it grows toward the free edge.
- 14. Outer layer of skin
- 15. Fatty or oily secretion produced by the sebaceous glands
- 17. Tiny, smooth muscles attached to hair follicles, contraction causes the hair to stand upright
- 18. A thickened portion of the skin
