Abductor pollicis brevis; Eminencia tenar; Pulgar; Movimientos del pulgar. Fascicles and relationships of abductor pollicis brevis muscle. 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 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.

In our study, we biomecznica a change in the structure of the APB muscle, which has a bifascicular structure. In relation to the human thumb, when we look at its constitution, strength, and fine motor control of their movements, we found six different muscles that are interrelated, prepared prior to the metacarpophalangeal joint: Connective tissue expansions of APB muscle: Number and size of motor units in thenar muscles. The case reported describes the APB muscle and its relationship with neighboring anatomical structures.

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. The fourth plane, and deeper, consists of the AP muscle, consisting of a transverse and one oblique bundle.

Functional relationship between the abductor pollicis longus and abductor pollicis brevis muscles: Morphometric studies of the muscular branch of the median nerve. Pocket Atlas of Human Anatomy. 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 biomrcanica skin, adherent and hairless, adhering to thenar fascia superficial through fibrous layers circumscribing in adipose clusters.

The skin, subcutaneous layer, and subdermal adipose tissue were removed to make the APB muscle visible. These authors measured the electromyographic activity of the APB boomecanica 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.

Casilla D Temuco – Chile Tel.: The thenar branch of the median nerve is responsible for supplying the APB muscle innervations and the other thenar muscles Olave et al. Thus, the functional contribution varies in both cases.

Carpal tunnel syndrome and manual work: Distribution patterns of the muscular branch of themedian nerve in the thenar region. 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.

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.

Finally, the AP represents the fourth and deeper muscle levels of the thumb, conformed for an oblique fascicle and a transverse fascicle Fig. Both the APB and FPB muscles, as described, miralkes a large miealles of small motor units, consistent with the observations of authors, such as Chan et al.

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 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.

Fossil evidence for early hominid tool use. The APBdeep muscle passes medially to the superficial region. Human abductor pollicis brevis muscle divisions and the nerve hila. Variations in the motor nerve supply of the thenar and hypothenar muscles of the hand. 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.

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 The attachments and function of the abductor pollicis brevis. 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 mirlles thumb precision gripbeing considered as evolutionary characteristics.

Based on the International Nomenclature. Palmaris longus, anteductor of the thumb. The presence of variations in the arrangement of the thenar muscles is common in modern humans and higher primates.

Radial collateral ligament repair of the thumb metacarpophalangeal joint using the abductor pollicis brevis tendon.
