yes they look right to me

Yes, you are correct about the roles of the scapula. The scapula, also known as the shoulder blade, has several important functions in the human body:

1. Aids movement of the shoulder joint: The scapula provides attachment points for multiple muscles involved in shoulder movements. Muscles attached to the scapula help control the rotation, elevation, and retraction of the shoulder joint, allowing for a wide range of arm movements.

2. Provides support: The scapula acts as a base of support for the arm and shoulder complex. It helps maintain the stability and proper alignment of the shoulder joint, allowing for efficient and controlled movement of the upper limb.

3. Attachment of collarbone to the humerus: The scapula has a shallow socket called the glenoid cavity, which forms part of the shoulder joint. The collarbone (clavicle) is attached to the scapula at a bony prominence known as the acromion process. The scapula's attachment points provide stability and help transmit forces between the collarbone and upper arm bone (humerus), facilitating movements of the shoulder complex.

Overall, the scapula plays a vital role in supporting and enabling a wide range of movements in the shoulder joint.
