Abstract

Aim of the study is to document the presence or absence of each papillary muscle in the right ventricle, its variation in the number, attachment, size, shape, anterior papillary muscle and number of tendinous cords at the origin from the papillary muscle and compare the results with previously existing data and to provide clinical correlation. The double head variety is seen more often in the anterior. This study on the variation of papillary muscles of the right ventricle helps to provide categorical outlay for management & provides additional information to the clinicians who will help them in deciding the diagnosis and management.

Abstract

Falx cerebelli is a sickle shaped Dural folds that usually harbors a single occipital venous sinuous at its posterior attachments. A study of falxcerebelli in 40 cadavers was done in Department of Anatomy Sivaraj Institute of Medical Sciences. In 4 specimens, accessory falx cerebelli was observed. The length and thickness of falx cerebelli was measured and compared with normal falx cerebelli and its sinuses were observed. Variation in the falx cerebelli showing marginal sinus, accessory sinus draining in to sigmoid sinus were observed. Neurosurgeons and Neuroradiologist should be aware of such variations as these could be potential source of haemorrhage or may lead to erroneous interpretation during imaging of the posterior cranial fossa.
