Tissue membranes are physical
barriers
- tissue membrane forms physical barrier membranes (epithelium) that line/ cover body surfaces,
which are supported by connective tissue
- TYPES
- Mucous membranes / mucosae line passgeways and
chambers that communicate with exterior — digestive,
respiratory, reproductive, urinary tract epithelial
surfaces if the passageways must be kept moist (by
mucus produced by mucous cells/multicellular glands)
to: reduce friction and facilitate absorption and
secretion lamina propria — areolar tissue component
of mucous membrane simple columnar epithelial of
digestive tract has mucous membrane that assist in
absorption and secretion
- Cutaneous membrane skin that covers
surface of body thick, waterproof and
dry has stratified squamous epithelium
and a layer of areolar tissue reinforced
by dense connective tissue
- Synovial membrane lines joint cavity has
serous fluid (lube) that fills joint cavities
that lies at the end of articulating bones —
protects the ends of bones membrane has
extensive area of areolar tissue containing
a matrix of interwoven collagen fibers,
proteoglycans and glycoproteins does not
have a true epithelium because: 1. develops
within connective tissue 2. no basement
membrane3. gaps up to 1mm — separates
adjacent cells4. fluid and solutes
continuously exchanged b/s synovial fluid
and capillaries
- Serous membranes — thin, firmly attached to body wall and to
organs they cover line the sealed, internal cavities of trunk —
cavities that are not open to exterior minimize friction b/w
surfaces it covers membranes have mesothelia (permeable)
supported by areolar tissue volume of serous membrane, called
transudate in this situation, can increase if there is hydrostatic
and osmotic imbalance
- visceral portion (serosa) — covers outer
surfaces of visceral organs
- parietal portion — lines inner surface of cavity
- types
- peritoneum — lines peritoneal
cavity and covers abdominal organs
- pericardium — lines pericardial cavity and covers heart
- pleura — lines pleural cavities and covers lungs
- peritoneum — lines peritoneal
cavity and covers abdominal organs
- visceral portion (serosa) — covers outer
surfaces of visceral organs

chambers that communicate with exterior — digestive,
respiratory, reproductive, urinary tract epithelial
