The lateral portion (acromial end) of the clavicle is positioned anterior or posterior?
What is the role of the conoid ligament?

> Group 3 = Middle 1/3rd
In terms of the scapula what aspect forms the shoulder joint?
The glenoid fossa
What does the spine of the scapula continue on to form?
The Acromian of the scapula
What is the name of the fossa superior to the spine of the scapula?
The supraspinous fossa
What is the name of the fossa inferior to the spine of the scapula?
The infraspinous fossa
What is found at the superior aspect of the glenoid fossa?
The supraglenoid tubercle
What is found at the inferior aspect of the glenoid fossa?

What type of joint is the sternoclavicular?
Synovial saddle joint
What is the fear aspect of the scapula known as?

What is the ring of fibrocartilage surrounding the glenoid fossa called?
The glenoid/acetabular labrum
What is the role of the glenoid labrum?
The ring of fibrocartilage surrounding the glenoid fossa allows a wider and deeper joint increasing its stability.

Which ligament(s) fix the clavicle to the coracoid process?
1) Trapezoid (In front)
2) Conoid (Behind)
What is meant by the scapula-thoracic joint?
Although not a true joint it is the movement of the scapula on the thoracic wall allowing full abduction of the shoulder joint
