Study Notes
Skin Layers and Functions
- The epidermis is responsible for producing keratin, a protein that hardens and flattens skin cells.
- The dermis layer performs essential functions such as sweating and blood circulation.
Skin Pigmentation
- Melanocytes are the cells in the skin that synthesize melanin, which gives skin its color.
Skin Conditions and Reactions
- The general term for a wound, injury, or abnormality in the skin is known as a lesion.
- A wheal is a round, swollen area typically seen in allergic reactions.
- A vesicle is a small, fluid-filled raised spot on the skin.
Immune and Sensory Response
- Langerhans cells determine the appropriate adaptive immune response in the skin, reacting to factors like inflammation or tolerance.
- Merkel cells combine with nerve endings to create a sensory receptor responsible for the sense of touch.
Skin Injuries
- Abrasion refers to a scraping away of the skin surface caused by friction.
- A blister larger than 5mm in diameter is referred to as a bulla.
