Cancer of superficial stem cells. Very treatable, most common type of skin cancer. | Basal Cell Carcinoma |
Cancer of Squamous layer of skin cells. Less common. | Squamous Cell Carcinoma |
Cancer of deep Melanocyte cells. | Malignant Melanoma |
Immune response, stimulating defense against microorganisms, skin cancer. | Langerhans Cells |
Basic component of hair and nails. | Keratin |
Evaporating water from your skin. | Insensible Perspiration |
Produced by active sweat glands. | Sensible Perspiration |
Orange, yellow pigment that accumulates in skin cells. | Carotene |
Brown, yellow-brown, or black pigment produced by melanocytes. | Melanin |
Produce melanin. | Melanocytes |

Individuals lose their melanocytes. (white patches) | Vitiligo |
Skin ulcers due to lack of proper blood flow. | Bedsores |
Tissue death. (lack of blood flow) | Necrosis |
Ruptured blood vessels. (bruise, "black & blue" | Contusion |
Inflammation of the skin. (contact dermatitis, Eczema, diaper rash, hives) | Dermatitis |
Smooth muscle that pulls on hair follicles & forces the hairs to stand erect. (goose bumps) | Arrector Pili |
Oil glands. | Sebaceous Glands |
Secrete into hair follicles. Bacteria found on secretions. (armpits, nipples, groin) | Apocrine Sweat Glands |
Discharge secretions onto the skin surface. Sensible perspiration. (eccrine) ( | Merocrine Sweat Glands |
99% water, also contains electrolytes. (mostly nacl) | Sweat |
Cool skin surface to reduce body temp. Excrete water & electrolytes. Protect skin from environmental hazards. (dilutes harmful chem., discourages microorganism growth) | Functions of Merocrine Sweat Glands |
Epidermis thins. Langerhans cells decrease. Vitamin D3 declines. Melanocyte activity declines. Glandular activity declines. | Ageing of the Integumentary System |
