Which of the following joints normally has 360 degree circumflexion?
- A- The knee
- B- The shoulder
- C- The elbow
- D- The finger tips
Out of the listed options, only the shoulder joint has close to 360 degrees of circumflexion.
Here's a breakdown of the movement capabilities of each joint:
- The knee:
This joint is a hinge joint that primarily allows flexion and extension, with some limited rotation. It does not have 360 degrees of movement.
- The shoulder:
This joint is a ball-and-socket joint, which allows for the widest range of motion in the human body. It can move in multiple planes, including flexion, extension, abduction, adduction, internal rotation, and external rotation. While not a complete 360 degrees, the shoulder joint has the closest range of motion to this description.
- The elbow:
This is a hinge joint that primarily allows for flexion and extension. Similar to the knee, it does not have 360 degrees of movement.
- The finger tips:
These joints are a combination of hinge and saddle joints, allowing for flexion, extension, abduction, adduction, and some limited circumduction. However, the range of motion in these joints is significantly less than 360 degrees.
