Study Notes
Skin Overview
- A dermatologist specializes in diseases and disorders concerning skin, hair, and nails.
- Healthy skin exhibits a fine-grained texture and remains smooth.
Skin Structure
- Skin appendages include hair, nails, sudoriferous glands (sweat), and sebaceous glands (oil).
- The layers of skin, from outermost to innermost, are epidermis, dermis, and subcutaneous tissue.
Skin Functionality
- As skin cells die, they migrate to the surface, replenishing the dead cells shed from the stratum corneum.
- The layer just beneath the epidermis is known as the papillary layer.
Tissue Characteristics
- Subcutaneous tissue contributes to body smoothness and contour, stores fats for energy, and provides a protective cushion for the skin.
Nerve Functionality
- Motor nerve fibers are responsible for innervating the arrector pili muscles linked to hair follicles.
