CASE PRESENTATION This case report presents a bilateral variation of an accessory abductor digiti minimi muscle in a male specimen. Ulnar artery and ulnar nerves were taken into accou...

Except for the two slips of the little finger, the two radial slips were inserted into the dorsal aponeurosis of the middle finger and the ring finger, respectively. The middle slip was connected to the junctura tendinum in the fourth interme...

Discharges of single motor units at voluntary contraction of abductor digiti minimi muscle in man.

Isometric tension in a muscle can be graded by varying the firing rate of each motor unit as well as by varying the number of units which are recruited. Several important reports have been published dealing with the relation between the tension produced in a muscle and firing rate of single motor units in voluntary contraction in human muscles 2-4. However, the question of how the firing rate c...

Morphologic Aspects of Abductor digiti minimi Muscle in the Hand

It is cited at the anatomical literature that the Abductor digiti minimi muscle can be composed by one or more muscular beams (Williams et al., 1995; Murata et al., 2004), being more found presenting only one beam, as described by Testut (1911) and schematized in pictures by other authors (Grant, 1948; Testut & Latarjet, 1959; Gray, 1977; Lockhart et al., 1983; Woodburne, 1984).
