The shoulder joint is a ball and socket joint, allowing for a wide range of motion including rotation. The humerus bone fits into the shallow socket of the scapula, allowing for rotation along with other movements.
The shoulder joint provides the greatest range of motion and flexibility compared to other joints in the body. Its ball-and-socket structure allows for movements in multiple directions.
The shoulder joint, also known as the glenohumeral joint, is a ball-and-socket joint that has the greatest range of movement in the body. It allows for movements in multiple directions, including flexion, extension, abduction, adduction, and rotation.
The shoulder is an example of a ball-and-socket joint, where the head of the humerus articulates with the glenoid fossa of the scapula. This joint provides a wide range of motion, allowing for movements like flexion, extension, abduction, adduction, and rotation of the arm. The surrounding muscles, ligaments, and tendons help stabilize and support the shoulder joint during movement.
It seems there might be a typo in your question. If you meant to ask about the sternoclavicular joint, it refers to the joint between the sternum (breastbone) and the clavicle (collarbone). This joint allows for movements of the shoulder and arms.
Shoulder flexion and abduction increase the range of motion in the shoulder joint by allowing the arm to move forward and away from the body, respectively. These movements help to improve flexibility and mobility in the shoulder joint.
the glenoid cavity is where the bone from the arm does all it's movements. it's essentially the "socket", if you consider the shoulder joint a ball and socket joint.
Ball and socket joint allows the above movements. Shoulder and hip joints are classic examples of this type of joints. Shoulder joint is much more mobile and circumduction movement is well marked in that joint.
Flexion, extension/hyperextension, trabsverse horizontal abduction, circumduction.If you think about the movements that you can do at your shoulder, you can figure this question out yourself. When in the anatomical position, we can perform flexion and extension,the forward and backward (respectively) movements of our arm at the shoulder joint. There is also abduction and adduction, which is the movement of rising our arm out to our sides, away from our body (abduction) and towards our body (adduction). Finally, there is also medial rotation and lateral rotation of the shoulder joint, in which we rotate the head of humerus in the shoulder-joint cavity (glenoid cavity). You may hear the combined movements of flexion, extension, abduction and adduction referred to as circumduction.
Abduction is when the shoulder moves away from the body, while adduction is when the shoulder moves towards the body.
Shoulder flexion is the movement of raising the arm forward, while shoulder extension is the movement of bringing the arm backward. These movements impact the range of motion and function of the shoulder joint by allowing the arm to reach different positions and perform various tasks. Flexion helps with activities like reaching overhead, while extension is important for movements like throwing or pulling. Both movements are essential for a full range of motion and functional use of the shoulder joint.
The rotator cuff muscles in the shoulder joint help to stabilize and rotate the arm bone (humerus) within the shoulder socket. They also assist in lifting and rotating the arm, as well as maintaining proper shoulder joint function during various movements.

The shoulder joint, also known as the glenohumeral joint, is a ball-and-socket joint that has the greatest range of movement in the body. It allows for movements in multiple directions, including flexion, extension, abduction, adduction, and rotation.
During flexion, the shoulder joint allows the arm to move forward and upward, increasing the range of motion. During extension, the shoulder joint allows the arm to move backward and downward, decreasing the range of motion.
In the arm, the ball joint is located at the shoulder, where the humerus (the upper arm bone) connects to the scapula (shoulder blade). This ball-and-socket joint allows for a wide range of motion, enabling movements such as raising, rotating, and swinging the arm. While the elbow is a hinge joint, the shoulder's ball joint is crucial for the arm's overall flexibility and mobility.
