Bones of the Upper Extremity
Scapula Also known as your
shoulder blade
Triangle shaped
There is a notch next to the coracoid process where 3 muscles attach and act as a cord that runs through there
Scapula The part that attaches to
the humerus is called the glenoid process
The part that sticks out in your back is the spine of your scapula
The scapula attaches to the head of the humerus
Deltoid and trapezius muscles attach here
Clavicle Also known as the
collar bone The clavicle sits on the
top of your scapula Attaches at the
acromion process Protects the shoulder
joint
Clavicle Because of its location and the way it sits on the
shoulder, the bone is weak and this is why many dislocations and separations occur
Less movable joint than the scapula
Separated Shoulder
Dislocated shoulder
Humerus Attaches to your
scapula and to the radius and ulna
Radial groove on posterior side makes up your elbow
Technical name for elbow is olecranon
Humerus Greater Tubercule – where muscle inserts
into somewhat rougher surface of the biceps and triceps (lateral)
Lesser Tubercule – insert of muscles from the scapula (medial)
Medial and lateral epicondyles are the pointy parts of your elbow
Radius & Ulna End of radius is on
your thumb side End of ulna is on your
little finger side Head of the ulna is
the bony part of the elbow
Radius & Ulna Attachment to the
wrist is called the Styloid process – carpal joint and brachioradiolis muscle
Trochler notch is where the bottom of the humerus sets in
The Hand
The Wrist Carpals (Wrist)
Move the metacarpals
Pinky Finger – Humate
Ring Finger – Humate
Middle Finger – Capitate
Pointer Finger – Trapezoid
Thumb – Trapezium
The Fingers Metacarpals
5 Metacarpals Phalanges
14 Phalanges Proximal Middle Distal
