An occipital emissary foramen has been traditionally described as a foramen present in the squamous part of the occipital bone at the occipital protuberance transmitting a vein that connects the confluence of sinuses with the occipital vein. The present study was done on 221 South Indian adult modern human skulls of unknown sex in the Department of Anatomy, St John's Medical College, Bangalore, India. The foramen was observed in 21/221 (9.

Estimation of total length of humerus from its segments.

The aim of the present study was to calculate the total length of the humerus from its segments using linear, transverse and sagittal measures. One hundred and fifty dry adult unpaired humeri of both sides and of unknown sex from South India were studied. The humeri were divided into eight segments using salient bony points and muscular markings.

Variations in brachial plexus and the relationship of median nerve with the axillary artery: a case report.

Background: Brachial Plexus innervates the upper limb. As it is the point of formation of many nerves, variations are common. Knowledge of these is important to anatomists, radiologists, anesthesiologists and surgeons.

Supratrochlear foramen of the humerus.

The presence of the supratrochlear foramen was studied in 150 dry adult humeri, of unknown sex from the Department of Anatomy, St John's Medical College, Bangalore: The dimensions of the foramen were measured. In bones where the foramen was absent, opacity or translucency of the septum was observed. A supratrochlear foramen was found in 28% of the total humerii.
