- Stratum basale
- Sudoriferous (sweat) gland:
- Stratum corneum
- a the deepest cell layer of the epidermis, lies closest to the dermis and is connected to it along a wavy borderline that resembles corrugated cardboard.
- b the outer layers of the skin; an epithelium
- c the glands that produce a saline solution called sweat.
- d 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)
- e the deep layer of the skin; composed of dense, irregular connective tissue
5 Multiple choice questions
- the deepest skin layer, contains irregularly arranged connective tissue fibers, as well as blood vessels, sweat and oil glands and deep pressure receptors called lamellar corpuscles.
- a clear, watery fluid secreted by the cells of a serous membrane.
- glands that empty their sebum secretion into hair follicles.
- membrane that lines the fibrous capsule of a synovial joint.
- a tough, insoluble protein found in tissues such as hair, nails, and epidermis of the skin.
5 True/False questions
Integumentary system → the skin and its accessory organs.
Melanocytes → the dark pigment synthesized by melanocytes responsible for skin color.
Subcutaneous tissue → essentially is adipose tissue. Not part of the skin, but it does anchor the skin to underlying organs and provides a site for nutrient (fat) storage. The tissue serves as a shock absorber and insulates the deeper tissues from the extreme temperature changes occurring outside the body. (responsible for women's curves).
Pleura → the oily secretion of sebaceous glands.
Sebum → 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.
