Three general Membranes!
Our goals Describe the 3 membrane types – And subtypes Know what tissue each is made of Determine where each would be found Describe each of their general functions
Membranes They cover and line parts of the body Made of more than one layer of at least 2 type tissue What is made of more than one tissue??
Serous Membranes Line organs and walls in ventral cavities (what cavities reside there?) Moist! Make sliding along each other possible! 2 layers 1.) simple squamous epithelium 2.) thin Areolar CT
Serous Membrane Functions Enrich fluid from capillaries with some cell adhesion molecules Fluid between membrane allows for slight movement
2 types of serous membranes Visceral serosa – lines organ Parietal serosa – lines cavity wall
Mucous Membranes Lines cavities “open” to exterior Wet and moist! Secretes mucous and other products Don’t forget it is great for absorbtion Layers: 1.simple Squamous or columnar 2.Loose CT 3.Smooth muscle (maybe)
