De Luca and Erim (4) examined interaction of motor units in the extensor carpi radialis longus and extensor carpi ulnaris
muscles during isometric wrist extensions.
The usual ACNM as well as the ulnar artery was thin (rudimentary), but superficially there were two thick arteries branching from one short stem originating in the cubital fossa to form the AB (termed "arteria mediana superficialis and arteria ulnaris
The wrist joint was extended during the arm movement due to concurrent stimulation of the extensor carpi ulnaris
16) Tenosynovitis is also a common feature of RA, particularly involving the flexor digitorum, extensor digitorum, and extensor carpi ulnaris
tendons (Figure 17).
The transverse carpal ligament and the tendon of flexor carpi ulnaris
insert into the pisiform.
The muscles differentiate from superficial to deep one, with the flexor digitorum profundus, flexor carpi radialis, and flexor carpi ulnaris
splitting off first, followed by the flexor pollicis longus.
The distal half of the SUA, from the level of the mid-forearm to wrist, follows a typical course for the ulnar artery: at the wrist it was accompanied medially by the ulnar nerve and the tendon of the flexor carpi ulnaris
, then traversed the superficial part of the flexor retinaculum, and continued across the palm as the superficial palmar arterial arch.
The stabilizer muscle that works with the ADMM is the flexor carpi ulnaris
The original orthopedic surgeon examined the child when she was 7 years old and determined that the flexor carpi ulnaris
tendon had been completely severed with a partial injury to the ulnar nerve.
2006) observed a decrease in the instantaneous mean frequency in the extensor carpi ulnaris
