- Stratum corneum
- Hair follicle
- Apocrine gland
- a slightly slanted compound structures. The inner epidermal sheath is composed of epithelial tissue and forms the hair. The outer dermal sheath is actually dermal connective tissue. Dermal region supplies blood vessels to the epidermal portion/reinforces it.
- b a tough, insoluble protein found in tissues such as hair, nails, and epidermis of the skin.
- c the outermost layer, 20 to 30 cell layers thick and accounts for ¾ of the epidermal thickness. Shinglelike dead cell remnants, full of keratin. The layer provides a durable overcoat for the body. Protects deeper cells from hostile environment(air) and from water loss. Resists biological, chemical, and physical assaults. Layer is replaced by cells produced by the division of the deeper stratum basale cells. New epidermis every 25 to 45 days. (flakes off as dandruff)
- d the oily secretion of sebaceous glands.
- e Sweat glands in the pubic and underarm areas that secrete thicker sweat, that produce odor. (secretions contain water, salts, fatty acids, and proteins)
5 Multiple choice questions
- a scale-like modification of the epidermis that corresponds to the hoof or claw of other animals. Has a free edge, a body(visible attached portion), and a root (embedded in the skin).
- membrane that forms the linings of body cavities open to the exterior (digestive, respiratory, urinary, and reproductive tracts)
- a clear, watery fluid secreted by the cells of a serous membrane.
- glands that have ducts through which their secretions are carried to a body surface (skin or mucosa)
- a clear secretion that is primarily water plus some salts (sodium chloride), vitamin C, traces of metabolic wastes (ammonia, urea, uric acid), and lactic acid(the chemical that accumulates during vigorous muscle activity) sweat is acidic pH from 4-6. Sweat reaches the surface through ducts that opens as a pore.
5 True/False questions
Epithelial membrane → membrane that lines the fibrous capsule of a synovial joint.
Melanocytes → the dark pigment synthesized by melanocytes responsible for skin color.
Cutaneous membrane → membrane that forms the linings of body cavities open to the exterior (digestive, respiratory, urinary, and reproductive tracts)
Pericardium → a tough, insoluble protein found in tissues such as hair, nails, and epidermis of the skin.
Reticular layer → the upper dermal region. It is uneven and has peglike projections from its superior surface, called dermal papillae, which indent the epidermis above.
