- The inferior glenohumeral ligament has the most functional significance, acting as the primary anterior_______of the shoulder when the arm is abducted 90 degrees.
- Any deviation from the anatomical posture generates increased tension in soft tissue and increased loading on the_______structures.

- With the elbow bent, the_______normally has a range of 140-180 degrees of rotation available.
- There is more mobility than stability in the_______joint.
- The first and second ribs have a particular influence on the shoulder and the neck due to_______muscle attachments, nerve and blood supplies.

- The_______connects with the humerus at the glenohumeral joint and with the clavicle at the acromioclavicular joint.
- They are_______oriented so that their directions of pull can produce rotatory as well as linear motions of the bone.
- The_______joint permits motion in the anterior and posterior directions about a longitudinal axis, in the cranial and caudal directions about a sagittal axis, and in rotation about a coronal axis.
