ABCD rule assessing moles: asymmetric, broder irregularity, color, diameter (larger than 6mm) apocrine glands arrector pili sweat glands in the pubic and underarm areas that secrete thicker sweat, that produce odor when come in contact with bacteria on the skin Tiny, smooth muscles attached to hair follicles; cause the hair to stand upright when activated. ceruminous glands wax glands, ear wax, deters insects and blocks entry of foreign materials contact dermatitis inflammation of the skin caused by contact with certain chemicals or substances
cutaneous membrane The skin, composed of stratified squamous epithelium and dense connective tissue; the only dry membrane. cuticle In a hair, the outermost single layer of cells that overlap one another like shingles is called the. dermal papillae a fingerlike projection of the dermis that may contain blood capillaries or Meissner corpuscles (of touch) dermis Layer of skin deep to the epidermis; composed of dense irregular tissue. eccrine gland produces true sweat; abundant on the palms of hand, soles of the feet, and forehead
eccrine glands most numerous, important, and wide spread of the sweat glands, mostly on forehead, upper lip, palms and soles; regulate temperature epidermis keratinized stratified squamous epithelium; outer layer of the skin epithelial membranes exocrine glands covering and lining membranes; consist of an epithelial sheet attached to an underlying layer of connective tissue; include: cutaneous membrane, mucous membranes, serous membranes duct glands that produce a substance that travels through small tube-like ducts, such as the sudoriferous (sweat) glands and the sebaceous (oil) glands goblet cells Mucus secreting cells in mucous membranes, columnar epithelial cells that contain a large vacuole with mucus
hypodermis integumentary system the subcutaneous tissue just deep to the skin made up of mostly adipose tissue Consists of the skin, mucous membranes, hair, and nails keratin Water-soluble protein found in the epidermis, hair, and nails that makes those structures hard and water-repellent. keratinocytes 90% of epidermis cells; make keratin lucidum The skin that covers the palms of the hands and the soles of the feet has an extra layer of epidermis called the stratum.
lunula The white crescent area located over the nail matrix is called the. malanocyte A cell that produces melanin. melanin melanocytes mucous membrane (mucosa) dark brown to black pigment produced by melanocytes; UV protection 8% of epidermis cells, produce pigment melanin, contributes to skin color moist epithelial membranes that line cavities that are exposed to the outside
papillary layer responsible for fingerprints; abundant capillary networks, furnishes nutrients to the epidermis; pain and touch receptors pericardium a double-layered serous membrane that surrounds the heart peritoneum Double-layered membrane surrounding the abdominal organs peritoneum Serous membrane lining the interior of the abdominal cavity and covering the surfaces of abdominal organs. pleura Two-layered serous membrane that lines the thoracic cavity and covers the external surface of the lung.
reticular reticular layer sebaceous glands The deepest layer of the dermis is called the layer. Accounts for 80% of the thickness of the dermis, dense fibrous irregular connective tissue oil glands of the skin; associated with hair follicles serous fluid Clear, watery fluid secreted by cells of a serous membrane. serous membrane Membrane that lines a cavity without an opening to the outside of the body (except for joint cavities).
serous membrane (serosa) shaft epithelial membranes that line internal cavities The part of a hair that projects from the surface of the scalp or skin is called the. subcutaneous tissue (hypodermis) layer of loose connective tissue/adipose tissue that is below the dermis sudoriferous gland Epidermal gland that produces sweat. synovial membranes connective tissue membrane that lines the synovial joint cavity
terminal hairs heavy, pigmented' head, eyebrows, and eyelashes; other parts of body after puberty vellus hairs soft, fine, cover body surface vernix caseosa visceral The white, cheesy-looking substance that is produced by the sebaceous glands and protects a baby's skin while it is floating in its water-filled sac inside the mother is called. The layer of the serous membrane that covers an organ is known as the layer.
