Integumentary ( LAB) Flashcards
lines body cavities and form protective sheets
Body membranes
represented by synovial membranes
connective tissue membranes
consists of cutaneous, mucous, and serous membranes
epithelial membranes
exposed to air and is a dry membrane
epithelial membrane
composed of stratified squamous membranes
epidermis
composed of dense connective tissues
dermis
type of epithelial membrane that rests on a connective tissue membrane called lamina propria. it also lines all body cavities that open to the exterior
mucous membrane
known as serosa, this epithelial membrane lines body cavities that are closed to the exterior
serous membranes
type of serous membrane that lines a specific portion of the ventral body cavity
parietal layer
this type of serous membrane covers the outside of the organ in that cavity
visceral membrane
largest organ of the body which takes 15-20% of the body weight. this organ protects, insulates, and synthesizes vitamin D
skin
a type of connective tissue membrane that is composed of areolar connective tissues and lines the fibrous capsules, and surrounding joints to provide a smooth and lubricated surface
synovial membrane
first layer of the integumentary system that is made up of keratinocytes that produces keratin
epidermis
layer of epidermis that protects the body from infection and is waterproof
corneum
layer of epidermis that is found on palms and soles
lucidum
layer of epidermis that retains water and regulates heat
granulusum
layer of epidermis that protects basale
spinosum
known as germinativum, this layer of epidermis has melanocytes and is a site of epidermal regeneration
basale
this is formed from a strong shearing force applied to the skin. layers may separate and interstitial fluid then accumulates in the space
blister
layer of the skin that is known as corium and “true skin”. it has elastin and collagen for elasticity and toughness
dermis
upper layer of dermis that forms fingerprints/footprints
papillary layer
lower layer of dermis
reticular layer
this layer of the skin contains lymphatics, nerve endings, blood vessels, sebaceous and sweat glands
dermis
one of the receptors found in the dermis that receives pain and itch
free nerve endings
one of the receptors found in dermis that reacts to light touch
merkel’s receptors
another receptor found in dermis that reacts to light touch
meisner’s receptors
one of the receptors found in dermis which responds to heat
ruffini’s corpuscles
one of the receptors found in dermis that reacts to cold
Kraus end bulbs
