Vocab Pt. 2 Flashcards
Glands develop when epithelial invigilate into underlying connective tissue and differentiate into secretory units
Epithelial Membrane
Cutaneous membranes = skin = Integumentary system
Cutaneous Membrane
Epithelial tissue that secretes mucus and that lines many body cavities and tubular organs including the gut and respiratory passages
Mucous Membrane
Mesothelial tissue that lines certain internal cavities of the body, forming a smooth, transparent, two-layered membrane lubricated by a fluid derived from serum
Serous Membrane
Used for various bodily fluids that are typically pale yellow and transparent and of a benign nature
Serous Fluid
Serous membrane lining the cavity of the abdomen and covering the abdominal organs
Peritoneum
Each of a pair of serous membranes lining the thorax and enveloping the lungs in humans and other mammals
Pleura
Membrane enclosing the heart, consisting of an outer fibrous layer and an inner double layer of serous membrane
Pericardium
Specialized connective tissue that lines the inner surface of capsules of synovial joints and tendon sheath
Synovial Membrane
Thin layer of tissue forming the natural outer covering of the body of a person or animal
Skin
Tough outer protective layer, especially that of an animal or plant
Integument
Fibrous protein forming the main structural constituent of hair, feathers, hoofs, claws, horns, etc
Keratin
Outer layer of cells covering an organism, in particular
Epidermis
Thick layer of living tissue below the epidermis that forms the true skin, containing blood capillaries, nerve endings, sweat glands, hair follicles, and other structures
Dermis
Deepest layer of the five layers of the epidermis, the outer covering of skin in mammals
Stratum Basale
Layer of the epidermis found between the stratum granulosum and stratum basale
Stratum Spinosum
Thin layer of cells in the epidermis
Stratum Granulosum
Thin, clear layer of dead skin cells in the epidermis named for its translucent appearance under a microscope
Stratum Lucidum
Horny outer layer of the skin
Stratum Corneum
Dark brown to black pigment occurring in the hair, skin, and iris of the eye in people and animals
Melanin
Small gland in the skin which secretes a lubricating oily matter into the hair follicles to lubricate the skin and hair
Sebaceous Glands
Oily secretion of the sebaceous glands
Sebum
Small sweat glands that produce a fluid secretion without removing cytoplasm from the secreting cells and that are restricted to the human skin
Eccrine Glands
Secretes a viscous fluid into a hair follicle, is lined with a single layer of usually columnar cells, and typically does not become active until puberty
Apocrine Glands
Small secretory cavity, sac, or gland, in particular
Hair Follicles
Small muscles attached to hair follicles in mammals
Arrector Pili
Fungal infection affecting the skin between the toes
Athlete’s Foot
Painful, pus-filled bumps that form under your skin when bacteria infect and inflame one or more of your hair follicles
Boils and Carbuncles
Inflamed blister in or near the mouth, caused by infection with the herpes simplex virus
Cold Sores
Red, itchy rash caused by direct contact with a substance or an allergic reaction to it
Contact Dermatitis
Contagious bacterial skin infection forming pustules and yellow, crusty sores
Impetigo
Skin disease marked by red, itchy, scaly patches
