Fascia and compartments of the distal arm
Section at the junction of distal third and proximal two thirds of the humerus
Biceps brachii
Musculocutaneous nerve
Coracobrachialis
Brachial artery
Cephalic vein
Lateral cutaneous nerve of
forearm which has just branched off
Median nerve
from the MUSCULOCUTANEOUS nerve
Brachialis
Posterior cutaneous nerve of
forearm which has just branched off
Basilic vein
from the RADIAL nerve
Medial cutaneous nerve
of forearm which arises
Deep artery of the arm
from the MEDIAL CORD of the
brachial plexus
Radial nerve
Lateral
head
Medial
head
Ulnar nerve
Long
head
Superior ulnar collateral artery
Section at the level of the humeral epicondyles
Triceps brachii
Basilic vein
Cephalic vein
Brachial artery
Radial nerve which has pierced the
lateral intermuscular septum a little while
ago, and now travels between brachialis
and brachioradialis
Median nerve
Biceps brachii
Brachioradialis
Brachialis
PRONATOR TERES
which is important for
a number of reasons:
-
-
Forms the lateral border
of the cubital fossa
Innervated by the RADIAL NERVE
Flexes the forearm, unlike
the rest of the forearm extensor
compartment
Together with the Supinator, they
are the only extensor compartment
muscles which do not cross the wrist
and cause no movement there
Ulnar nerve
Anconeus
Triceps Brachii tendon
Which is unimportant, and arguably useless. In fact some anatomists believe it to a rudimentary 4th
triceps head. If it were missing, you would likely not notice.
