Body Membranes Quiz

Serous Membranes = Found lining body cavities that do not open up directly to the outside Mucous Membranes = Found lining cavities that directly open up to the outside of the body Synovial Membranes = Form the inner lining of joint cavities Cutaneous Membranes = An organ of the integumentary system - Skin

Parietal layer = Lining the wall of the cavity Visceral layer = Covers the organs/structures inside the cavity

Skin = Has a surface area of 1.2 to 2.2 square meters (varies) Accessory organs = Include sweat glands, oil glands, hair, finger nails and toe nails

<p>Serous Membranes = Produce a lubricating watery fluid located between the two layers Mucous Membranes = &quot;Moist&quot; membranes bathed by fluid, some contain goblet cells (mucus secreting cells)</p> Signup and view all the answers

<p>Acne = Inflammatory disease of sebaceous glands caused by bacteria thriving on sebaceous gland secretions Athletes Foot = Fungus infection often present on the soles and between the toes of the feet Decubitus Ulcers = Tissue damage and ulcerations as a result of deficiency of blood due to prolonged pressure against an underlying bony projection Impetigo = Highly contagious bacterial skin infection characterized by pus-filled sacs that rupture and become crusted over</p> Signup and view all the answers

<p>First degree burn = Only epidermis is affected, characterized by mild pain and erythema, will heal in two to three days and may be accompanied by flaking and peeling Second degree burn = Extends through the entire epidermis and part of the dermis, erythema, pain and blistering develops in the area of the damaged skin, heals within 10 to 14 days with little scarring depending on extent of burn Third degree burn = Entire thickness of skin is destroyed, surface is leathery and may be tan, brown or black in appearance, no pain in immediate area because pain receptors are destroyed, regeneration of tissue is slow with much scarring even with grafts</p> Signup and view all the answers

<p>Moles = Pigmented tumors found in skin, vary in color from yellow to brown to black, average about 20 per person Warts = Result of a viral invasion of the skin causing epithelial cells to proliferate, most regress spontaneously Burns = Tissue damage due to thermal (heat), electrical, radioactive, or chemical agents, can destroy the proteins in exposed cells causing injury or death to the cells Skin Cancers = See Textbook Pg 165, Know 3 main types and characteristics</p> Signup and view all the answers

<p>Moles = Grow slowly over a period of time, remain stable for a long period of time and then slowly diminish in size Warts = Most regress spontaneously, genital warts (herpes virus) can be spread through sexual contact Burns = Types: Partial thickness burns, Full thickness burns Skin Cancers = See Textbook Pg 165, Know 3 main types and characteristics</p> Signup and view all the answers

<p>Epidermis = Outer most layer composed primarily of a stratified squamous epithelium Dermis = Connective tissue layer found below the epidermis with embedded protein fibers Stratum Basale = Deepest single cell layer of cells, in contact with basement membrane, cuboidal in shape Stratum Corneum = Outermost layer of skin, approximately 20-30 layers of dead anucleated keratinized cells</p> Signup and view all the answers

<p>Eccrine Sweat Glands = Most numerous sweat gland, activated in times of elevated body temperature, most open up directly onto skin surface by way of a pore Apocrine Sweat Glands = Approx. 2000 become active at puberty, produce sweat when a person is emotionally upset, frightened, in pain and during sexual arousal, most open up into hair follicles Sebaceous Gland = Groups of specialized epithelial cells associated with hair follicles, release a fatty oil like substance called Sebum Hair Follicles = Present on all skin surfaces except palms, lips, nipples, parts of external reproductive organs, tube like depressions of the epidermis and into dermis contain the hair root which grows from dividing cells at the base of the follicle</p> Signup and view all the answers

<p>Papillary dermis = Outer most superficial layer consisting of areolar CT and small blood vessels, its outer surface form projections called dermal papillae Reticular dermis = Accounts for 80% of the dermis thickness, contains collagen fibers in bundles and networks, blood vessel networks (plexus) found at bottom border provide nourishment Stratum Basale = The deepest single cell layer of cells, in contact with basement membrane, cuboidal in shape Stratum Corneum = The outermost layer of skin, approximately 20-30 layers of dead anucleated keratinized cells</p> Signup and view all the answers

<p>Keratinocytes = Produce the fibrous protein Keratin and glycolipids which along with the cell junctions act as a waterproofing barrier for skin Melanocytes = Produce melanin which is responsible in part for skin color Sweat Glands = Tiny tube-like exocrine glands with coiled ends lined with epithelial cells that produce and release sweat Sebaceous Gland = Groups of specialized epithelial cells associated with hair follicles, release a fatty oil like substance called Sebum</p> Signup and view all the answers
