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.

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.
(6,7) Key trigger points include: (8) Key trigger point Associated satellite trigger point sternocleidomastoid temporalis, masseter upper trapezius temporalis, masseter scalene deltoid, extensor carpi radialis, extensor digitorum communis splenius capitis temporalis supraspinatus deltoid, extensor carpi radialis infraspinatus biceps brachii pectoralis minor flexor carpi radialis

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.
