Appendicular Skeleton Flashcards
Scapula
Two bones often called the shoulder blades
Superior border
Superior edge
Medial border
Medial edge, next to vertebral column
Lateral border
Lateral edge, next to the axilla
Superior angle
Between superior and medial borders
Lateral angle
Inferior glenoid fossa
Inferior angle
Between medial and lateral borders
Acromion process
Lateral point of the shoulder, articulates with clavicle
Coracoid process
Inferior and anterior to acromion process
Glenoid fossa or cavity
Shoulder “socket”
Spine of the scapula
Posterior structure
Supraspinous fossa -
Posterior, superior to spine
Infraspinous fossa
Posterior, inferior to spine
Subscapular fossa
Anterior, concave towards rib cage
Clavicle
Two bones that connect to sternum on either side
Sternal end
Medial end, articulates with sternum
Acromial end
Lateral end, articulates with acromion process
Humerus
Previously known as brachial bone
Head
Smooth rounded proximal portion
Anatomical neck
Narrowing distal to head
Greater tubercle
Proximal
Intertubercular groove (bicipital)
Between 2 tubercles
Deltoid tuberosity
Lateral shaft
Olecranon fossa
Posterior, inferior fossa for olecranon process
Capitulum
Distal, lateral smooth, rounded knuckle
Trochlea
Distal, medial, pointed knuckle
Medial and lateral epicondyle
Bony mass proximal to the capitulum and trochlea
Ulna
Medial forearm bone
Olecranon process
Proximal, posterior, point of elbow, fits in olecranon fossa,
superior lip of trochlear notch
Radial notch
Articulates with head of radius
Trochlear notch
Articulates with the trochlea from the humerus
Head
Distal end
Styloid process
Distal, projection from head
Coronoid process
Inferior lip of trochlear notch
Radius
Lateral forearm bone
Head
Proximal end, looks like spool
Neck
Distal to head
Radial tuberosity
Proximal end
Ulnar notch
Distal end, articulates with ulna
