Function of body membranes
cover body surfaces, prevent fluid loss, surround internal organs for protection
All membranes of the integumentary system
are classified as...
epithelial or connective tissue
Epithelial membranes are made of what membranes?
Cutaneous, Mucous, & Serous Membranes
Epithelial membranes are composed of a layer of?
epithelial tissue over connective tissue
Tissue type of cutaneous membrane:
Epithelial tissue
Location of cutaneous membrane
the skin covering the body
function of cutaneous membrane
Protects body tissue and organs
Upper layer of epithelial membrane are composed of?
Dead Keratinized squamous cells
Tissue type of mucous membrane:
epithelial tissue
location of mucous membranes
Openings to outside world (digestive, respiratory, urinary, and reproductive systems)
function of mucous membrane
Secrete Mucouse for protective and lubricating purposes.
What connective tissue does the mucous membrane rest on?
Lamina propia
Mucosae is often composed of?
stratified squamous or simple columnar
Ex of stratified squamous epithelium
mouth/esophagus
ex of simple columnar
digestive tract
Mucous membranes are "___" membranes
wet
Which part of the body does not secrete mucous?
Urinary Tract
Tissue type of serous membrane:
simple squamous epithelium
location of serous membranes
internal organs
two layers of serous membrane
parietal layer and visceral layer
Parietal layer
Facing out into the body cavity
Visceral Layer
Faces in toward the organ
What fluid is secreted by the membranes to separate parietal and visceral layers?
serous fluid
function of serous fluid
prevent friction between membranes
Tissue type of synovial membrane:
connective tissue
location of synovial membrane
lines joints
function of synovial membrane
secretes lubricating fluid
Lubricating fluid allows...
bones and dense connective tissues to slide pass each other without damage
