The APB muscle, with its fusiform shape, shows two fascicles that are arranged one above the other, connected by a loose areola tissue for easy removal.

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.

Variations in the motor nerve supply of the thenar and hypothenar muscles of the hand. The case reported describes the APB muscle and its relationship with neighboring anatomical structures.

The The attachments and function of the abductor pollicis brevis. Use of quantitative abductor pollicis brevis strength testing in patients with carpal tunnel syndrome. Thus, the functional contribution varies in both cases. Human abductor pollicis brevis muscle divisions and the nerve hila. 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.

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. The skin, subcutaneous layer, and subdermal adipose tissue were removed to make the APB muscle visible. Connective tissue expansions of APB muscle: Abductor pollicis brevis; Eminencia tenar; Pulgar; Movimientos del pulgar.


Based on the International Nomenclature.

The remaining inserts are part of the deep fascicle APBdeep of the APB muscle, which are directed to the APL tendon, scaphoid tuberosity, flexor retinaculum, and tubercle of the trapezium. Contractile properties of human motor units in health, aging, and disease.

With its flattened appearance, the APBdeep muscle thins as it approaches the insertion site; this issue does not receive tendinous expansions. Distribution patterns of the muscular branch of themedian nerve in the thenar region.

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

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 biomeacnica hand to maintain tension deep fascicle of APL and the movements of the thumb to prevent undesired movements of the hand and forearm.

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. Abductor pollicis brevis muscle; Thenar eminence; Thumb; Movement of the thumb.

Number and size of motor units in thenar muscles. The miral,es 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. 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 APBdeep muscle passes medially to the superficial region. Barcelona, Editorial Masson, 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 this article, we report the presence of a superficial portion mkralles the APB muscle and its relationship and discuss the available literature and the clinical implications of the presence of this variation. 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 miralles aspects of these two muscle fascicles.

The thenar branch of the median nerve is responsible for supplying the APB muscle innervations and the other thenar muscles Olave et al. Casilla D Temuco – Chile Tel.: Fascicles and relationships of abductor pollicis brevis muscle.

Morphometric studies of the muscular branch of the median nerve.
