part 3 Flashcards
Articular surfaces are flat
plane
Cylindrical projections of one bone fits into a trough-shared surface on another,
hinge
Allow only slipping or gliding movement
plane
Motion is along a single plane
hinge
Uniaxial joints permit flexion and extension only
hinge
Rounded end of one bone protrudes into a “sleeve” or ring composed of bone
pivot
Only uniaxial movement allowed
pivot
Oval articular surface of one bone fits into a complimentary depression in another
condyloid/ellipsoidal joints
Biaxial joints permit all angular motions
condyloid/ellipsoidal joints
Similar to condyloid joints, but allow greater movement
saddle joints
Each articular surface has both a concave and a convex surface
saddle joints
Spherical or hemispherical head of one bone articulates with a cup-like socket of another
ball and socket joints
Multiaxial joints permit the most freely moving joints
ball and socket joints
What type of joint is the shoulder joint, and what is an advantage and disadvantage?
ball and socket, most freely moving, but easy to dislocate
What type of joint is the hip, and what is a disadvantage?
ball and socket, easy to dislocate
