Exercise 11 Flashcards
Rounded end of Clavicle, towards the shoulder
Acromial end of Clavicle
Flat end, towards the sternum
Sternal end of Clavicle
Platelike extension, forms the apex of the shoulder. Articulates with the clavicle which forms the bridge from the appendicular to the axial skeleton
Acromion process of the Scapula
The vague resemblance to a crows beak, but is shaped more like a bent finger. Provides a surface for attachment of tendons of the biceps brachii and other muscles
Coracoid process of Scapula
A shallow socket that articulates with the head of the humerus, forming the glenohumeral joint

Canal on top of the scapula where muscles attach
Supraspinous Fossa of Scapula
Inferior large plate on the outside of the scapula where muscles of the shoulder attach

Largest plate on the inside of the scapula
Subscapular Fossa of the Scapula
Border towards the middle of the body on the scapula
Medial border of the Scapula
Spine of the scapula, dividing the superior and inferior parts of the scapula
Scapular spine
Top of the arm towards the shoulder, interacts with scapular. A bulb.
Head of the Humerus
Larger of the two bumps towards the head of the humorus, superior to the other smaller one.
Greater Tubercle of the Humerus
Smaller, inferior of the two bumps towards the head of the humerus
Lesser Tubercle of the Humerus
Space between the greater and lesser tubercle
Intertubercular Sulcus of the Humerus
Slight bump in the middle of the Humerus that muscles attach to
Deltoid Tuberosity
A pocket of ligament/cartilage sitting between the humerus head and the scapula
Glenoid Labrum
