bones, joints and movements Flashcards
(15 cards)
what are the 2 types of cartilage
hyaline and fibro
what is the function of hyaline?
provides a smooth firm surface between articulating bones preventing friction and shock absorbing.
what is the function of fibro?
tough and slightly flexible actin acting as a shock absorber
structure and function of the joint capsule?
2 layered outer fibrous capsule providing the joint with strength and support
synovial membrane
inner layer that secretes synovial fluid increasing range of motion
structure and function of bursa
fluid filled fibrous sack containing fluid. lubricates and increases rom of the joint
structure and function of pads of fat
act as a wedge between capsule and bone/muscle increasing stability and shock absorbing
structure and function of menisci
wedge of fibro cartilage. increases stability between articulating bones and shock absorbs to decrease damage to surface of the bones.

articulating bones in the shoulder
scapular, humerous
abductor in shoulder
medial deltoid
medial rotator muscle in shoulder
