Upper Appendages and Pectoral Girdle

Clavicle

S shaped bone that connects the pectoral girdle to the axial skeleton by the sternum

Acromial end

End of clavicle that articulates with the scapula

Sternal end

End of clavicle that articulates with the sternum

Scapula

Shoulder blade; connects the arm to the clavicle

Superior angle

The medial/superior corner of the scapula

Lateral angle

The lateral, thickest part of the scapula

Inferior angle

The inferior corner of the scapula

Superior boarder

The edge of the scapula that runs along the top portion of the bone

Lateral boarder

The edge of the scapula that runs inferior to the lateral angle

Medial boarder

The edge of the scapula that runs inferior to the superior angle

Subscapular Fossa

Depression that covers majority of the scapula facing the ribs

Coracoid process

hook shaped protuberance from scapula that acts as an anchor point for muscles and ligaments

Acromion

Bony projection that articulates with the clavicle

Scapular spine

bony ridge off scapula that is a muscular anchor point

Supraspinous fossa

The depression superior to the scapular spine

Infraspinous fossa

The depression inferior to the scapular spine

Glenoid fossa

Depression directly inferior to the acromion of the scapula; forms the socket of the shoulder joint

Humerus

upper arm bone; articulates with scapula to make shoulder

Head of Humerus

rounded top part of humerus that articulates with the scapula to make shoulder joint

Greater Tubercle

Larger projection next to the head of the humerus

Lesser Tubercle

Smaller projection next to the head of the humerus

Bicipital Groove

found between tubercles

Surgical neck

the narrow part between the head/tubercles and the shaft

Anatomical Neck

holds the head to rest of the bone

Deltoid Tuberosity

slight protuberance midway down shaft

Lateral Epicondyle

lateral protrubance on the distal end of the humerus

Medial Epicondyle

Medial protuberance on the distal end of the humerus

Capitulum

Small rounded protuberance on the distal end of the humerus, lateral side; articulates with the radius

Trochlea

Spool shaped protuberance at the distal end of the humerus, medial side; articulates with the ulna

Olecranon Fossa

depression in the posterior side of the distal end of the humerus; receives the olecranon process of the ulna

Coronoid Fossa

depression in the anterior distal end of the humerus; receives the coronoid process of the ulna

Radial Fossa

Depression lateral to the coronoid fossa; receives the radius

Coronoid Process

bottom protuberance of the C shape at the top of the ulna; is received by the coronoid fossa

Olecranon process

Top protuberance of C shape at the top of the ulna; is received by the olecranon fossa

Trochlear notch

Inner part of C shape that articulates with the trochlea of the humerus

Radial Notch

depression on side of C shape of ulna that receives the radius

Styloid Process of Ulna

Small point on distal end of the ulna; allows for wrist and pinky mobility and ligament attachment

Radial Head

Round head that articulates with the capitulum of the humerus

Radial Neck

connects the head to the shaft of radius

Radial Tuberosity

prominence on the medial side of the radius just distal of the neck; serves as an attachment point for muscles

Ulnar Notch

depression at the distal end of the radius that articulates with the ulna

Styloid Process of the Radius

Projection from the distal end of the radius; ligament attachment

Scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, hamate

Carpals

Metacarpals

between carpals and phalanges; I,II,III,IV,V (thumb to pinky)

Phalanges

distal to metacarpals; proximal, middle, and distal; I, II, III, IV, V
