Unusual morphology of the superior belly of omohyoid muscle
Rajesh Thangarajan,Prakashchandra Shetty,Srinivasa Rao Sirasanagnadla,Melanie Rose D'souza 대한해부학회 2014 Anatomy & Cell Biology Vol.47 No.4
Though anomalies of the superior belly of the omohyoid have been described in medical literature, absence of superior belly of omohyoid is rarely reported. Herein, we report a rare case of unilateral absence of muscular part of superior belly of omohyoid. During laboratory dissections for medical undergraduate students, unusual morphology of the superior belly of the omohyoid muscle has been observed in formalin embalmed male cadaver of South Indian origin. The muscular part of the superior belly of the omohyoid was completely absent. The inferior belly originated normally from the upper border of scapula, and continued with a fibrous tendon which ran vertically lateral to sternohyoid muscle and finally attached to the lower border of the body of hyoid bone. The fibrous tendon was about 1 mm thick and received a nerve supply form the superior root of the ansa cervicalis. As omohyoid mucle is used to achieve the reconstruction of the laryngeal muscles and bowed vocal folds, the knowledge of the possible anomalies of the omohyoid muscle is important during neck surgeries.

A rare case of persistent jugulocephalic vein and its clinical implication
Prakashchandra Shetty,Satheesha B. Nayak,Rajesh Thangarajan,Melanie Rose D’Souza 대한해부학회 2016 Anatomy & Cell Biology Vol.49 No.3
Persistence of jugulocephalic vein is one of the extremely rare variations of the cephalic vein. Knowledge of such a variation is of utmost importance to orthopedic surgeons while treating the fractures of the clavicle, head and neck surgeons, during surgery of the lower part of neck, for cardiothoracic surgeons and radiologists during catheterization and cardiac device placement. We report the persistent jugulocephalic vein in an adult male cadaver, observed during the routine dissection classes. The right cephalic vein ascended upwards, superficial to the lateral part of the clavicle and terminated into the external jugular vein. It also gave a communicating branch to the axillary vein below the clavicle. We discuss the embryological and clinical importance of this rare variation.
