- Arrector pili
- Stratum corneum
- a the deep layer of the skin; composed of dense, irregular connective tissue
- b the serous membrane covering the lungs and lining the thoracic cavity.
- c the oily secretion of sebaceous glands.
- 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 a smooth muscle attached to hair follicles that causes "goose bumps" to appear on the skin when contracted
5 Multiple choice questions
- 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)
- 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.
- the membranous sac enveloping the heart.
- 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.
5 True/False questions
Mucous membrane → membrane that lines a cavity without an opening to the outside of the body (except for joint cavities, which have a synovial membrane); serosa.
Epidermis → the outer layers of the skin; an epithelium
Sweat → the oily secretion of sebaceous glands.
Integumentary system → 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.
Papillary layer → the upper dermal region. It is uneven and has peglike projections from its superior surface, called dermal papillae, which indent the epidermis above.
