Here is a well-labeled diagram of the mammalian skin:
1. Epidermis: The outermost layer of the skin composed of epithelial cells.
2. Dermis: The middle layer of the skin that contains connective tissues, blood vessels, and sensory receptors.
3. Subcutaneous tissue: The innermost layer of the skin that consists of fat cells and provides insulation and cushioning.
4. Hair: A filamentous structure that grows from hair follicles in the skin.
5. Sebaceous gland: Produces sebum, which helps lubricate the hair and skin.
6. Sweat gland: Produces sweat, which helps regulate body temperature.
7. Artery: A blood vessel that carries oxygenated blood away from the heart to the skin.
8. Vein: A blood vessel that carries deoxygenated blood back to the heart from the skin.
9. Nerve endings: Transmit sensory information such as touch, temperature, and pain.
10. Pacinian corpuscle: A specialized nerve ending that detects pressure and vibration.
11. Meissner's corpuscle: A specialized nerve ending that detects light touch and low-frequency vibrations.
12. Hair follicle: A pocket in the skin where hair growth occurs.
13. Epidermal ridges: Ridges on the surface of the skin that help improve grip and enhance touch sensitivity.
14. Eccrine sweat duct: A duct that transports sweat from the sweat gland to the skin's surface.
15. Pore: An opening on the skin's surface through which sweat is released.
16. Adipose tissue: Fat cells that store energy and provide insulation.
17. Blood vessels: Tubes that transport oxygen, nutrients, and other substances throughout the body.
18. Sebaceous duct: A duct that transports sebum from the sebaceous gland to the hair follicle or skin's surface.
