Why is the shoulder joint more movable than the hip joint?

The shoulder joint is less influenced by muscle attachments than the hip joint.

The shoulder joint is supported by stronger ligaments than the hip joint.

The shoulder joint has a shallower socket compared to the hip joint.

The shoulder joint is a hinge joint, while the hip joint is a ball-and-socket joint.

Verified step by step guidance

Identify the type of joints involved: The shoulder joint is a ball-and-socket joint, and so is the hip joint. This means both joints allow for a wide range of motion, but there are differences in their structure that affect mobility.

Examine the structure of the shoulder joint: The shoulder joint, also known as the glenohumeral joint, has a shallow socket called the glenoid cavity. This shallow socket allows for greater mobility but less stability.

Examine the structure of the hip joint: The hip joint, also a ball-and-socket joint, has a deeper socket called the acetabulum. This deeper socket provides more stability but limits the range of motion compared to the shoulder.

Consider the role of ligaments and muscles: While both joints are supported by ligaments and muscles, the shoulder joint relies more on muscle support due to its shallower socket, allowing for greater movement.

Conclude with the main reason for increased mobility: The primary reason the shoulder joint is more movable than the hip joint is due to its shallower socket, which allows for a greater range of motion at the expense of stability.
