Lipoma is a benign mesenchymal tumor that develops in abundant areas of fatty tissue. Its location the hand rare. The first lipoma was described by Stein 1959. targeted localizations hands concern thenar and hypothenar eminences, more rarely digital localizations. clinical symptomatology varies according to location, with progressively increasing size leading hold on mobility fingers risk neuro...

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 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.

The derived proportions of the human hand may provide supportive buttressing that protects the hand from injury when striking with a fist. Flexion of digits 2-5 results in buttressing of the pads of the distal phalanges against the central palm and the palmar pads of the proximal phalanges. Additionally, adduction of the thenar eminence to abut the dorsal surface of the distal phalanges of digi...

19 Cortex–muscle coherence (CMC) reflects coupling between magnetoencephalography (MEG) 20 and surface electromyography (sEMG), being strongest during isometric contraction, but absent, 21 for unknown reasons, in some individuals. 22 We used a novel non-magnetic high-density sEMG (HD-sEMG) electrode grid (36 mm x 12 23 mm; 60 electrodes separated by 3 mm) to study effects of sEMG recording site...
