*Membranes
| Question | Answer |
|---|---|
| Epithelial Layer sitting on a thin layer of? | Connective Tissue ( Lamina propria) |
| 4 Types Of Membranes,/ what are they? | Mucous--Serous--Synovial--Cutaneous(skin)-- |
| Mucous Membranes | Lines a body cavity that opens to the outside.(mouth,vagina,anus ect.-----------Epithelial cells form a Barrier to Microbes.- Tight junction between cells.-------------Mucous is secreted from underlying glands to keep surface moist. |
| Serous Membranes (Membrane on walls of cavity= Parietal layer and membrane over organs in cavity= Visceral layer). | Simple Squamous cells overlying loose Connective Layer.--- Squamous cells secrete slippery fluid.---Lines a body cavity that does NOT open to the outside such as a chest or abdominal cavity. Examples. Lungs(pleura),Peritoneum and Pericardium. |
| Synovial Membranes ( This is an exception of space that is not lined with Epithelial Tissue). | Lines joint cavities of all freely movable Joints. -- No epithelial cells lining this space.---Composed Connevtive Tissue that secretes Synovial Fluid containing Hyaluronic Acid and Interstital Fluid.-- |
| Connective Tissue with a Liquid Matrix = | The Plasma |
| Red Blood cells = | Erythrocytes.. carry oxygen and co2, connective tissue |
| White Blood cells = | Leukocytes.. Fights Infections |
| Cell Fragments called = | Platelets... Clots |
