Morphological Variations in Lumbricals of Upper Limb: A Cadaveric Study

Ajit Kumar, Amarnath Mishra, Durajan Goswami and Ganesh E

The hand is a prehensile organ, it is endowed with grasping and precision movements for skilled work and it acts as a chief tactile apparatus. This is contributed by a higher degree of neuromuscular co-ordination and a larger cortical representation of the hand in the sensory motor cortex of the brain. This study was done on 30 cadavers who were available in the Department of Anatomy, National Medical College, Birgunj, Nepal. 93.3% of the lumbricals were normal in origin, innervation and its insertion. Variations were found in many of the specimens. 6.67% of the lumbricals showed a proximal origin, in 3.3% of the total specimens, 2nd lumbricals were bipennate. 3rd lumbrical was absent in 6.67% of the specimens and 1stlumbrical was hypertrophied in 3.3%.
