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

Ring Finger – Humate
