-
reflect compromise between nee for strength versus need for mobility
articulations (joints)
-
the greater the mbility, the less the strength

synarthrosis,amphiarthrosis,diarthrosis
-
its a sin it cant move

-
what type of synovial joint permits the widest range of motion
ball and socket
-
types of synovial joints based on the shapes of the articulating surfaces
gliding, hinge, pivot, ellipsoid, saddle, ball and socket
-
