Classification of Membranes

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
