The presence of variations in the arrangement of the thenar muscles is common in modern humans and higher primates. Motor units and functional anatomy of the human musculus opponens digiti minimi.

Barcelona, Editorial Masson, The The attachments and function of the abductor pollicis brevis. In a male cadaver preserved through glycerin, belonging to the Morphology Laboratory, Department of Basic Biomedical Sciences, Universidad de Blomecanica, 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.

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. Based on the International Nomenclature.

In our study, we reported a change in the structure of the APB muscle, which has a bifascicular structure. 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.

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.

Functional relationship between the abductor pollicis longus and abductor pollicis brevis muscles: Finally, the AP represents the fourth and deeper muscle levels of the thumb, biiomecanica for an oblique fascicle and a transverse fascicle Fig.

Fascicles and relationships of abductor pollicis brevis muscle. Contractile properties of human motor units in health, aging, and disease.

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.

With its flattened appearance, the APBdeep muscle thins as it approaches the insertion site; this issue does not receive tendinous expansions.

Palmaris longus, anteductor of the thumb. Connective tissue expansions of APB muscle: 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 the 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.

Carpal tunnel syndrome and manual work: The differentiation from prehominids Australophitecus afarensis to hominids Homo habilis is due to the use of tools, which was only possible through the development of the brain and the opposition of the thumb precision gripbeing considered as evolutionary characteristics. The skin, subcutaneous layer, and subdermal adipose tissue were removed to make the APB muscle visible. The APBdeep muscle passes medially to the superficial region. For him, when you have this variation, the fibers form a superficial portion that is oriented above the deep fascicle of the ABS APBdeepand the latter by about the FPBsup muscle.

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 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.

The remaining inserts are part of the deep fascicle APBdeep of the APB muscle, which are directed to the APL tendon, mlralles tuberosity, flexor retinaculum, and tubercle of the trapezium. 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.

Muscle Nerve, 24 9: Both the APB and FPB muscles, as described, have a large number of small motor units, consistent with the observations of authors, such as Chan et al. Biomecanuca collateral ligament repair of the thumb metacarpophalangeal joint using the abductor pollicis brevis tendon. 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.

Human abductor pollicis brevis muscle divisions and the nerve hila. These actions are explained from the relationship and trajectory of the APB muscle on carpometacarpal and metacarpophalangeal joints of the thumb, which are traversed by that muscle.

The thenar branch of the median nerve is responsible for supplying the APB muscle innervations and the other thenar muscles Olave et al.
