Anatomical Variations in Relation to Anterior Group of Forearm Muscles

Abstract

The muscles are notoriously variable and is quite common to find muscular anomalies in the course of routine dissection of human body. The anterior group of muscles are often divided into three layers i.e Superficial, Intermediate and deep layer. During routine dissection of upper limb for medical undergraduates, the forearm was dissected in a 86 years old embalmed female cadaver in the department of Anatomy, Punjab Institute of Medical sciences Jalandhar. In the present case two variations were observed. Firstly ulnar nerve in the anterior compartment of forearm was passing through theflexor digitorum profundus muscle before running between it and flexor carpi ulnaris. Secondly there was an accessory muscle with short belly and its tendon was merging with flexor pollicis longus muscle. Both the variations were present bilaterally. In the practical sense one’s awareness of man’s anatomical variability may forestall surgical errors and excite new methods of restoration.
