|
Definition
Opposition is described as bringing the pad of the thumb in
contact with the pad of a finger. Reposition is the opposite. In
reality, opposition is the movement of the metacarpal shafts of
the thumb and little finger toward the midline. “Think of
rolling the metacarpal shaft toward the midline of the palm |

| describe the palmar aponeurosis |
|
Definition
The fascia of the palm is thickened centrally by a
triangular aponeurosis. This palmar aponeurosis lies
superficial to the flexor retinaculum to which it is
firmly attached. The apex of the palmar aponeurosis is
continuous with the expanded tendon of the palmaris
longus (when present). At its base the palmar
aponeurosis divides into four longitudinal bands which
extend toward each digit. The four longitudinal bands
of the palmar aponeurosis attach distally to fibrous
sheaths within each digit. |

Neurovascular Relationships in the Forearm:
Remember 3 nerves and the muscles they pierce (i.e. heads):
median n. = pronator teres
ulnar n. = flexor carpi ulnaris
radial n. = supinator
Remember 3 nerves and the arteries they travel with:
median n. = brachial artery in the arm
ulnar n. = superior ulnar collateral artery (arm) and ulnar artery (forearm)
radial n. = deep brachial artery (arm)
Remember what muscle the nerves travel deep to in the forearm:
median n. = deep to FDS and superficial to FDP
ulnar n. = deep to FCU
radial n. = deep to brachioradialis (superficial branch)

The ulnar artery (#2) is the larger of the two
terminal branches of the brachial artery.
● From the cubital fossa, the ulnar a. travels in the
forearm lateral to the ulnar n. and deep to FCU.
● The ulnar a. like the radial a. has important
branches that form anastomoses around the
elbow joint. The anterior and posterior ulnar
recurrent arteries anastomose with the inferior
and superior ulnar collateral arteries (branches of
the brachial artery), respectively.
● A common interosseous branch of the ulnar a.
emerges just distal to the cubital fossa. It divides
into anterior and posterior interosseous branches.
The anterior interosseus a. (#4,#6) travels with
the anterior interosseous n. (branch of median
n.). The posterior interosseous a. (#5) travels
with the posterior interosseous n. (continuation
of deep radial n.)
● Palmar and dorsal ulnar carpal branches
participate in anastomoses around the wrist.
● The ulnar a. enters the palm lateral to the ulnar n.
via the ulnar tunnel. The superficial palmar arch
is the direct continuation of the ulnar a.
Remember that the anterior interosseus n. is a branch of the median n. and that the posterior
interosseus n. is a branch of the radial n. They travel on the interosseus membrane with the
artery of the same name (branches of common interosseus artery supplied by the ulnar artery. |
