The number of Granule cells in the human cerebellar cortex and its quantitative variation with respect to age was studied in seventy human cerebellums using light microscopy. The study revealed a progressive decrease in number of granule cells with increase in the fibre components. The number of granule cells showed statistically significant negative correlation with age. This study provides more information regarding the quantitative histological structure of human cerebellar cortex.

A histological and morphological study of human thymus obtained from autopsy was done. A steady increase in weight of thymus till puberty and thereafter a steady decline was noted. Involution was by fatty infiltration after puberty. Hassall's corpuscles were seen in all the specimens and its size or shape had no relation to the age or involution of the gland. There was an increase in the number of Hassall's corpuscles till puberty after which a progressive decrease was observed.

Background: Due to its many variations, scapula became one of the most interesting bones of human skeleton. The acromion process projects forwards almost perpendicularly from the lateral end of spine of scapula. The acromion process is associated with a variety of ailments in the shoulder joint. As morphometry of the Acromion process of the scapula is an important factor implicated in impingement syndrome of the shoulder joint, the purpose of present study is to record the morphometric values of the acromion process and its morphological features in South Indian population.

Knowledge of anatomy of the branching pattern of external carotid artery (ECA) is needed for head and neck surgeries and diagnostic purposes. Previously knowledge regarding this was obtained from dissecting specimens. But with magnetic resonance angiograms being done widely, data from these may be taken for a better understanding of the branching pattern of ECA. To study the branching pattern of external carotid artery using MR angiograms taken for other purposes. A cross-sectional study was carried out in our institution, which is a tertiary care centre, between September 2013 and September 2015 in which we studied the MR angiograms of 50 patients. Out of the 50 MR angiograms studied, variations were seen in 5 cases. In two cases, the ascending pharyngeal artery was seen to arise from the lateral side instead of the medial side on the left side. In another two, the ascending pharyngeal artery was seen to arise from the occipital artery on the left side. In one case the superior laryngeal artery arose from the external carotid artery. MR angiogram taken for other purposes is an inexpensive, ionizing radiation free method which can be used to study the branching pattern of external carotid artery.
