Q

serous cavity functions

A

surrounds structures (abd. organs, heart, lung)
provide slippery, non-adhesive surface to reduce friction in movement of organs (between organs & body wall)
protects organs from external shock
allows organs to change shape & size
serous membrane used for transport of solutes & cells, body defense

A

lined by mucosa
mucus secreted by epithelial exocrine glands covers epithelial layer, for protection & lubrication

Q

synovial cavity

A

soft tissue between articular capsule & joint cavity of synovial joints, surround movable joints
lined by synovial membrane that secretes synovial fluid (clear, viscid, lubricating): reduce friction during movement
involves joint spaces & bursae (provide cushion between bone & tendon / muscle)

Q

fascial compartment

A

group of muscles working together functionally, supplied by mutual vessels & innervation
divided into multiple compartments for muscles & neurovascular bundles
function: hold structures together
e.g. upper & lower limb compartments

17
Q

fascial compartment clinical significance

A
  • compartments may contain or direct the spread of an infection or a tumour
  • fluid accumulation can cause ischemia and tissue necrosis if untreated
18
Q

anatomical compartment

A

area defined by anatomist, for description of area topography
