How to tell R and L Scapula:

the subscapular fossa behind you on top of
your own shoulder blade (smooth side
against your skin). The glenoid cavity
should face laterally, not towards the
vertebral column.

6. Head
How to tell R and L Humerus:
Hold the humerus on the anterior surface
of your arm with the olecranon fossa
touching your skin (facing posteriorly).
What direction is the head facing? It
should be should face medially towards
the body.
How to tell R and L Ulna:
Bend your elbow 90 degrees, then place
the ulna on your forearm with the
semilunar notch facing the ceiling. The
radial notch should be on the thumb side,
not the pinky side because the radius is on
the thumb side.

Don’t get the conoid (“cone shaped”)
tubercle of the clavicle mixed up with the
coracoid (“hook shaped”) process of the
scapula or the coronoid (“crow’s beak
shaped”) process of the ulna and of the
mandible!
Scapula has a “c” and so does coraCoid.
Ulna and Mandible have an “n” and so
does coroNoid.

Know the following on a single rib

How to tell true from false rib:
A true rib inserts directly into the sternum
(by way of its costal cartilage).
A false rib’s costal cartilage inserts into
the costal cartilage of the rib above it.
Two of the false ribs are floating ribs that
have no costal cartilages and do not insert
into the sternum at all.

direction is the head facing? It should be
should face medially towards the body.
How to tell R and L Tibia:
Place the tibia on the anterior surface of
your leg with the tibial tuberosity facing
anteriorly (not touching your leg). What side

The head is flatter on top and the malleolus is
pointy at the tip, and the malleolus has its smooth
facet more on the side of the bone, instead of on
