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.
In case of shoulder joint you have the glenoid cavity of the scapula taking part in joint formation. You have the glenoid labrum to increase the surface area of the glenoid cavity. The large head of the humerus takes part in joint formation.
no, the glenoid cavity is not in the clavicle. it is in the scapula, next to the acromion process and the coracoid process, which provide stability. the glenoid cavity articulates with the head of the humerus as a ball-and-socket joint.
With the clavicals (as well as) The coastal cartilage of the first and second ribs and the body of the sternum.
Ball and socket
The glenoid fossa of the scapula articulates with the head of the humerus, forming the shoulder joint. It is a shallow, cup-shaped socket that allows for a wide range of motion in the shoulder joint.
Coracoid Process. The coracoid process points anteriorly over the tip of the shoulder joint and serves as an attachment point for some of the upper limb muscles.
I'm assuming it's the clavicle bone which attaches to the sternum on the axial skeleton
There is a joint capsule full of synnovial fluid and the articular surfaces of both of the head of the humerus and the glenoid cavity are very reciprocal in their shape meaning that they fit together like a ball in glove for smooth movements
The shoulder is composed of the clavicle (collarbone), scapula (shoulder blade) and humerus (upper arm bone). The roof of the shoulder is formed the acromion. The shoulder actually has two joints to facilitate its movement.The acromioclavicular (AC) joint is located between the acromion and clavicle. The glenohumeral joint, or shoulder joint, is a ball-and-socket joint where the top of the humerus (the ball) fits into the glenoid cavity of the scapula (the socket). Muscles, tendons, and ligaments hold these bones together. Articular cartilage covers the surface of the shoulder joint, allowing the bones to glide smoothly and protects and cushions the joints.
Ball-and-Socket Joints. Smooth, hemispherical head fits within a cuplike socket. Only mutiaxial joints in the body are the shoulder joint - head of humerus into glenoid cavity of scapula and the hip joint - head of femur into acetabulum of hip bone.
No.1 Head of the humerus is fixed in socket of glenoid cavity or scapula thus forming shoulder joint. No.2 Head of femur in acetabulum of hip bone forming hip joint.
The humerous and the glenoid fossa form the ball-socket joint.
