Skin and Body Membranes

Serous Fluid A clear, watery fluid secreted by the cells of a serous membrane
Peritoneum The serous membrane lining the interior of the abdominal cavity and covering the surfaces of the abdominal organs
Pleura The serous membrane covering the lungs and lining the thoracic cavity
Pericardium The membranous sac enveloping the heart
Keratin A tough, insoluble protein found in tissues such as hair, nails, and epidermis of the skin
Epidermis The outer layers of the skin; epithelium
Dermis The deep layer of the skin; composed of dense, irregular connective tissue
Subcutaneous/Hypodermis Beneath the skin
Keratinocytes Epidermal cells that produce keratin
Stratum Basale "base layer" The deepest cell layer of the epidermis
Stratum Spinosum "spiny layer" Prickly layer found between the stratum granulosum and stratum basale
Stratum Lucidum "clear layer" A thin, clear layer of dead skin cells in the epidermis named for its translucent appearance under a microscope
Stratum Corneum "horny layer" The outermost layer
Melanin The dark pigment synthesized bu melanocytes; responsible for skin color
Melanocytes Cells that produce melanin
Papillary Layer Upper dermal region
Dermal Papillae Small, fingerlike projections from the dermis
Reticular Layer The deepest skin layer
Skin Appendage Skin-associated structures that serve a particular function including sensation, contractility, lubrication and heat loss
Sebum The oily secretion of sebaceous glands
Sweat Gland The glands that produce a saline solution called swear; also called sudoriferous glands
Eccrine Glands The major sweat glands of the human body, found in virtually all skin, with the highest density in palm and soles, then on the head, but much less on the trunk and the extremities
Nail A scalelike modification of the epidermis that corresponds to the hood or claw of other animals
Burn Tissue damage and cell death caused by intense heat, electricity, UV radiation (sunburn), or certain chemicals (such as acids)
1st Degree Burn Only the epidermis is damaged
2nd Degree Burn Injury to epidermis and upper region of dermis --- blisters appear
Partial-thickness Burn First and second degree burns
3rd Degree Burn Destroy entire thickness of skin
Full-thickness Burn Third-degree burn --- appears blanched or blackened
Apocrine glands The less numerous type of sweat gland --- produces a secretion containing water, salts, and proteins
Sweat 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 (a chemical that accumulates during vigorous muscle activity)
