Clavicle

collarbone, attaches anteriorly to the sternum, posterior to scapula

Scapula

shoulder blade

Acromion process

high prominence on the shoulder

Coracoid process

attachment site for upper back and shoulder muscles

Glenoid Cavity

shoulder joint, site where the scapula and humerus meet

Humerus

bone extending from the shoulder to the elbow

Head

articulates with the glenoid cavity

Greater/lesser tubercles

projections of the shoulder, laterally/anterioly

Deltoid tuberosity

roughened v-shape, attachment site for deltoid muscle

Trochela

articulates with the ulna

Capitulum

articulates with the radius

Olecranon fossa

posterior side of the elbow joint, receives the olecranon of the ulna when extended

Croronoid fossa

anterior fossa recieves the coronoid process of ulna when arm is flexed

Radius

bone in lower arm, thumb side

Radial head

articulates with capitulum of humerus and radial notch of ulna

Radial tuberosity

allows the bicept to attach to lower arm

Ulna

the inner and longer of the two bones of the human forearm, pinky side

Coronoid process

receives the trochlea of humerus with the olecranon

Olecranon process

forms the prominence of the elbow

Trochlear notch

curved area between the olecranon and coronoid processes

Carpals

writs bones, 8 per side

Scaphoid

boat shaped, most commonly fractured, below thumb

Capitate

largest wrist bone

Metacarpals

1-5 (thumb to pinky), attach distally to the carpals (10 in total)

Phalanges

each finger has 3 (proximal, medial, distal), except thumb (2), 28 in total
