- b a clear, watery fluid secreted by the cells of a serous membrane.
- c glands that empty their sebum secretion into hair follicles.
- d 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.
- 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
- 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.
- 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)
- 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).
- the glands that produce a saline solution called sweat.
- the serous membrane covering the lungs and lining the thoracic cavity.
5 True/False questions
Epidermis → the outer layers of the skin; an epithelium
Melanin → the dark pigment synthesized by melanocytes responsible for skin color.
Melanocytes → Cells that produce melanin.
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.
Keratin → the dark pigment synthesized by melanocytes responsible for skin color.
