What combines to make up membranes?
Epithelia and connective tissues
Name 4 types of membranes.
1) Mucous
2) Serous
3) Cutaneous
4) Synovial
Mucous Membrane
Mucous membranes are coated with the secretions of mucous glands. They line most of the digestive and respiratory tracts and portions of the urinary and reproductive tracts. Line passageways that communicate with exterior
Serous Membrane
Line ventral body cavities (pleural, peritoneum, pericardium); transparent, thin, prevents friction
Cutaneous Membrane
The skin; covers the outer surface of the body. In contrast to serous or mucous membranes, the cutaneous membrane is thick, relatively waterproof, and usually dry.
Synovial Membrane
Line join cavities (articulations) and produces the synovial fluid within the joint. the synovial fluid lubricates the cartilages in the joint, distributes oxygen and nutrients, and cushions shocks at the joint.
Serous Membranes
1) Thin, transparent- simple squamous epithelium + areolar
2) Attached to the body wall & organs they cover - ventral body cavity
3) Minimizes friction
* Lines open body cavities that are closed to the exterior of the body
* Serous layers separated by ser
What are the 3 serous membranes?
Pleural
Peritoneum
Pericardium
Pleural Membrane
Peritoneum
Pericardium
Balloon Example
Outer wall is comparable to parietal serosa
Air is comparable to serous fluid
Inner Wall is comparable to visceral serosa
