Synovial Joints: Types (Nursing)

00:02 So now we're going to segue into the different types of synovial joints that you have.

00:08 There are several different subtypes of synovial joints.

00:13 The first type of joint they will discuss is the plane joint.

00:17 The plane joint can be found in areas of the body such as the wrist, and a lot of those carpal bones.

00:24 This type of joint allows for the movement of back and forth as well as side to side at the joint.

00:33 A second type of joint that we find in synovial joints is the hinge joint.

00:39 An example of the hinge joint is going to be the elbow.

00:43 Unlike the plain joint where it can move back and forth and side to side, the hinge joint only allows one direction of movement that is flexion and extension.

00:57 The third type of joint is the pivot joint.

01:00 In this joint we are able to do rotation or movement laterally or medially.

01:07 A good example of this joint is the atlantoaxial joint in the spine.

01:12 This allows us to shake our head yes and no.

01:17 The fourth type of joint is going to be a condyloid joint.

01:21 This joint is very similar to a ball and socket joint which we will discuss shortly, except instead of a round shape, it's more of an ovoid shape.

01:31 You can find an example of this joint in the wrist.

01:35 This allows movement both back and forth, side to side, as well as circumduction.

01:43 The fifth type of joint that we'll discuss today is going to be the saddle joint.

01:49 An example of this joint can be found at the thumb.

01:53 This allows for both back and forth and side to side movement.

01:58 The final joint that we will discuss today is going to be the ball and socket joint.

02:03 This joint allows full rotation or full 360 degree movement at the joint.

02:11 A good example of this joint is the hip joint.

02:14 Another example of this would be the shoulder joint.

02:19 There are several factors that affect the range of motion at the different types of synovial joints.

02:24 First, the structure and the shape of the articulating bones determine the range of movement.

02:31 Secondly, the strength and the tautness of the joint ligaments that hold the joint together also can affect the range of motion.

02:41 Third, the arrangement as well as the tension of the muscles on the joint can also affect.

02:49 Lastly, contact of soft parts, hormones, as well as disuse or overuse can have an effect on the range of motion at the synovial joints.
