This study on the lumbricals was performed on 50 (100 specimens of human hands) embalmed donated cadavers (40 males & 10 females) in the department of Anatomy of K.J. Somaiya Medical College, Sion, Mumbai, India. The dissection of the palm was done meticulously to expose all the tendons of flexor digitorum superficialis and flexor digitorum profundus. The proximal and distal attachments of the lumbricals were seen. The arterial pattern of upper limb was also observed. The photographs of the variations were taken for proper ocumentation. Out of 100 specimens the variations were observed in 22 specimens. Out of 22 specimens in 7 specimens two bellies of second lumbrical were observed originating from the radial side of the tendon of both flexor digitorum profundus and flexor digitorum superficialis going to the middle finger, in 5 specimens an accessory belly of first lumbrical was observed originating from the radial side of the tendon of the flexor digitorum profundus going to the index finger and in remaining 10 specimens the bipennate second lumbrical originating from the ulnar side of the tendon of the flexor digitorum profundus going to the index finger and radial side of the tendon of the flexor digitorum profundus going to the middle finger was observed. There were no associated neuro vascular variations seen. All the variations were unilateral.
