Appendicular notes Flashcards
What connects each arm to the trunk and provides a basis for arm movement
Pectoral (shoulder) girdle
What does each girdle consist of
One clavicle, and one scapula
Where does the clavicle connect eith the axial skeleton
At the manubrium
Where does the clavicle articulate
Articulates with the acromionof the scapula (acromegaly end)
What is the articulation between clavicle and manubrium of sternum
Sternoclavicular joint
Flat, triangular shaped bone located on the posterior side of the rib cage, commonly known as a shoulder blade
Scapula
What does the scapula articulate with
Articulates with the clavicle and the humerus
What are the sides of a scapula
3 sides- superior border, medial border, lateral border.
What are the corners of each scapula
Superior angle inferior angle lateral angle
Glenoid cavity
Cup shaped articulating surface at the lateral angle
What does the glenoid cavity articulate with
Articulates with the humerus to form shoulder joint (glenohumeral joint)
What provides attachment points to ligaments and tendons of the shoulder
Scapular processes
Smaller process superior and anterior to the glenoid cavity
Coracoid process
Larger process superior and posterior to the glenoiud cavity
Acromion
Ridge across the posterior surface from the acromion to the medial border
Spine
What are the bones of the upper limbs
Arms, forearms, wrists, hands
A long bone in the arm, articulates with the scapula to the elbow and with the ulna and the radius at the elbow
Humerus
Proximal and medial rounded end that articualtes with the scapula
Head
Larger, rounded projection on the proximal lateral surface of the bone
greater tubercle
Forms the lateral contour of the shoulder and is important For muscle attachment
Greater tubercle
Smaller projection, anterior, medial to the greater tubercle, muscle attachment
Lesser tubercle
This seperates the tubercles by deep groves
Intertubercular sulcus
Between the tubercles and the articular surface of the head
Anatomical neck
Corresponds to metaphysics of growing bone
Surgical neck
