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.

flexor carpi radialis and
flexor carpi radialis muscles.

At the first and the second resolution level, the classification results of the wavelet-based correlation dimension method for two channels of SEMG signals recorded from the
flexor carpi radialis (FCR) and the extensor carpi radialis longus (ECRL) in five normally limbed subjects are summarized in Figure 1.
At the wrist, median nerve lies partly under the cover of the Palmaris longus tendon and partly between the
flexor carpi radialis and the Palmaris longus tendon.

The palmar sensory branch of the median nerve, which can be damaged in open procedures as well as in blind injections of the carpal tunnel, can be avoided, since it is visible under ultrasound along its course on the ulnar aspect of the
flexor carpi radialis tendon and distally in a more ulnar position.

The point is located bilaterally on the anterior surface of the forearm, approximately three finger widths up from the first wrist crease and between the tendons of the
flexor carpi radialis and palmarus longus (see Figure 1).
* Antidromic surface stimulation is performed at the wrist between Palmaris longus and
flexor carpi radialis tendons at second distal most crease.
Intraoperatively it was noted that the
flexor carpi radialis and other flexor forearm muscle groups were pale but viable.
If the SLL is intact,
flexor carpi radialis (FCR) is thought to be an important dynamic stabiliser of the scaphoid, possibly due to its compression action at the scaphotrapezial-trapezoid joint.
