- Sudoriferous (sweat) gland:
- Serous membrane
- Stratum basale
- Epithelial membrane
- Sebaceous gland
- 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 membrane that lines a cavity without an opening to the outside of the body (except for joint cavities, which have a synovial membrane); serosa.
- c glands that empty their sebum secretion into hair follicles.
- d composed of epithelial tissue and an underlying layer of connective tissue. (also called covering and lining membranes, include the cutaneous membrane, the mucous membranes, and the serous membranes.
- e the glands that produce a saline solution called sweat.
5 Multiple choice questions
- the skin and its accessory organs.
- found all over the body, they produce sweat, important in part of the body's heat-regulating equipment. Supplied with nerve endings that cause them to secrete sweat when the external temperature or body temperature is high.
- a smooth muscle attached to hair follicles that causes "goose bumps" to appear on the skin when contracted
- the oily secretion of sebaceous glands.
- 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).
5 True/False questions
Reticular layer → 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.
Stratum corneum → 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)
Keratin → the dark pigment synthesized by melanocytes responsible for skin color.
Melanocytes → Cells that produce melanin.
Nail → 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).
