Hello students, a synovial joint is the type of joint which is found between bones that move against each other such as the joints of the limb e .g.
00:13
Shoulder, hip, elbow and knee.
00:16
These synovial joints are further classified into 6 different categories based on the shape and structure of the joint.
00:24
The shape of the joint affects the type of movement permitted by that joint.
00:29
Talking about the mobility then, the least mobile joint is planar joint.
00:36
This joint range of motion is limited and does not involve rotation.
00:42
Planar joints are found in the carpal bones in the hand and the tarsal bone of the foot as well as between vertebrae.
00:51
The next joint is hinge joint.
00:55
In hinge joint, the slightly rounded end of one bone fits into slightly hollow end of the other bone.
01:03
In this way, one bone moves while the other remains stationary.
01:07
The elbow is an example of hinge joint.
01:11
The next joint is pivot joint.
01:13
This consists of the rounded end of one bone fitting into a ring formed by the other bone.
01:20
This structure allows rotational movement as the rounded bone moves around its own axis.
01:27
The joint of the wrist that allows the palm of the hand to be turned up and down is a pivot joint...
