Joint Structure And Function
Questions With 100% Correct
Answers
Joint structure and function
\.What are the function of joints?
1) allows movement in 3D
2) For weight bearing
3) Even transfer of load
\.What tissues are associated with joints?
1) Bone
2) Muscle
3) cartilage
4) Synovium (thin layer of cells lining tendon sheaths and articular cartilage, produces
lubrication of joint)
5) Synovial fluid (produced by synovium)
6) Capsules/dense-fibrous tissues/ ligaments
\.Structural classification of joints
FIBROUS (fixed joints, immovable)
(peg joint of teeth sockets, skull sutures, between long bones)
Sutures, syndesmoses, gomphoses
CARTILAGINOUS (some movement)
(intervertebral disc, pubic symphysis, manubriosternal joint, plate between epiphysis and
diapiphysis of growing long bones (temporary))
synchondroses, symphyses
SYNOVIAL (movable, joint surrounded by articular capsule)
, (metacarpophalangeal joint, knee, hip, elbow)
Ball and socket, condyloid joint, gliding joint, hinge joint, pivot joint, saddle joint
\.Functional classification of joint types
SYNARTHROSES
Immovable joints, mostly fibrous
AMPHIARTHROSES
Slightly movable, mostly cartilaginous
DIARTHROSES
Freely Movable, mostly synovial
\.SUTURES (fibrous joints, synarthroses)
Only occur in skull bones
Allows skull growth during development
Adj bones interdigitate
Junction filled with small, fine tissue fibres
\.SYNDESMOSES (fibrous joints)
Bones connected by ligament or interosseous membrane
Amount of movement proportional to fibre length
Tibiofibular joint
Radioulnar syndesmoses (interosseous membrane)
\.GOMPHOSES (fibrous joint)
Peg in socket joint
Found only in tooth articulation
\.SYNCHONDROSES (primary cartilaginous)
Directly connected to hyaline cartilage
Usually slight movable (amphiarthroses)
Ribs (slightly movable)
Hyaline cartilage plate between diapiphysis and epiphysis in growing long bones
\.SYMTHYSIS (secondary cartilaginous)
