ABSTRACT
Palmaris longus is one among the superficial flexor muscles of forearm possessing a short fusiform belly and a long tendon lying between the flexor carpi radialis and the flexor carpi ulnaris. It is phylogenetically a degenerating muscle which shows a lot of variations, the most common one being absence. Based on ethnicity, gender, race, and hand dominance, it may be absent in individuals either unilaterally or bilaterally. This paper describes the unilateral absence of palmaris longus muscle in the right forearm which was observed during routine cadaver dissection of a male cadaver aged about 65 yrs in the department of Shareera Rachana at Sri Dharmasthala Manjunatheshwara College of Ayurveda & Hospital, Hassan, Karnataka, India. The variation was compared with the presence of palmaris longus muscle of left limb and other possible variations of palmaris longus muscle reported in the literature. The prevalence of absence, related variations, clinical importance & evolutionary aspect of palmaris longus muscle has been discussed in the paper.
Key words: Palmaris longus, Flexor muscle, Variation
