CASE REPORT In a male cadaver preserved through glycerin, belonging to the Morphology Laboratory, Department of Basic Biomedical Sciences, Universidad de Talca, during routine dissection of the miralled thenar region, we observed an unusual variation to APB muscle; therefore, the muscle was carefully dissected, preserving the whole of it, as well as its attachments and surrounding anatomical structures.
Abductor pollicis brevis muscle; Thenar eminence; Thumb; Movement of the thumb. Use of quantitative abductor pollicis brevis strength testing in patients with carpal tunnel syndrome. Carpal tunnel syndrome and manual work: The skin, subcutaneous layer, and subdermal mirallew tissue were removed to make the APB muscle visible. These authors measured the electromyographic activity of the APB muscle and deep fascicle of the APL muscle in various positions of the thumb and hand, obtaining miralles conclusion that the ABS muscle is activated by the movements of the hand to maintain tension deep fascicle of APL and the movements of the thumb to prevent undesired movements of the hand and forearm.

Both the ABPsup and APBdeep muscles are inserted distally on the lateral tubercle of the base of the proximal phalanx of the thumb sesamoid bone and dorsal expansion Fig. For Susman, the greater variability in these species is observed in the deep fascicles of the FPL and FPB muscles; these variations are probably greater specialization relationships that upper hominids acquired through the thumb and the hand.
Fascicles and relationships of abductor pollicis brevis muscle. Abductor pollicis brevis; Eminencia tenar; Pulgar; Movimientos del pulgar.
Palmaris longus, anteductor of the thumb. Pocket Atlas of Human Anatomy. Abductor pollicis brevis muscle APB belongs to the foreground of the subfascial muscle thenar region, which is of great importance in the movement of the thumb on its two-joint arrangement.
Fossil evidence for early hominid tool use. Distribution patterns of the muscular branch of themedian nerve in the thenar region. In a male cadaver preserved through glycerin, belonging to the Morphology Laboratory, Department of Basic Biomedical Sciences, Universidad de Talca, during routine dissection of the left thenar region, we observed an unusual variation to APB muscle; therefore, the muscle was carefully dissected, preserving the whole of it, as well as its attachments and surrounding anatomical structures.
With regard to form, the APB is a fusiform muscle; it is flat, thin, and triangular and located at the surface of the thenar eminence, which is characterized by a thick skin, adherent and hairless, adhering to thenar fascia superficial through fibrous layers circumscribing in adipose clusters.
The APBsup muscle fibers are oriented parallel and slightly lateral to the APBdeep muscle fibers with a lower volume relative to its counterpart, being separated by a thin connective tissue and easily removed.

Thus, the functional contribution varies in both cases. Casilla D Temuco – Chile Tel.: Morphometric studies of the muscular branch of the median nerve. The fourth plane, and deeper, consists of the AP muscle, consisting of a transverse and one oblique bundle.
The superficial portion of the APBsup muscle is closely linked to the adipose and dermal tissues, receiving aponeurotic expansions of the tendinous portion of the PL muscle, the palmar aponeurosis, and the APL tendon Fig. The influence that this disposition is on the clinical behavior of the APB muscle is unclear, so it is necessary to develop biomechanical and electromyographic studies to elucidate the functional aspects of these two muscle fascicles.

In the clinical setting, the APB muscle was used for assessment, diagnosis, and treatment of various diseases and dysfunctions, such as dynamometry tests Liu et al. In our study, we reported a change in the structure of the APB muscle, which has mralles bifascicular structure. Based on the International Nomenclature.
In this case, an APB muscle with two fascicles, one superficial establishing close relation with the tegument of the thenar region and other deep subfascial location and morphology similar to the APB muscle in its classic description, was presented. In this article, we report the presence of a superficial portion of the APB muscle and its relationship and discuss the available literature and the clinical implications of the presence of this variation.
Variations in the motor nerve supply of the thenar and hypothenar muscles of the hand. The differentiation from prehominids Australophitecus afarensis to hominids Homo habilis is due to the use of tools, which was biomecqnica possible through the development of the brain and the opposition of the thumb precision gripbeing considered as evolutionary characteristics.
The presence of variations in the arrangement of the thenar muscles is common in modern humans and higher primates.
The APBdeep muscle passes medially to the superficial region. Of these, the first is located medially and deep enough to be visible almost in totality, as opposed to the OP mirallws, which is covered in a lateral plane and located in a deep region, although it can still be observed from a sagittal view.
The thenar branch of the median nerve is responsible for supplying the APB muscle innervations and the other thenar muscles Olave et al. Human abductor pollicis brevis muscle divisions and the nerve hila.
Napier said that the provision of the APB muscle, longitudinal along the axis, allows the separation of the metacarpal or proximal phalanx abduction and medial rotation addition because of its insertion into the dorsal expansion.
