Study of Number of Germinal Centers of Vermiform Appendix in Bangladeshi People of Different Age and Sex.

The vermiform appendix is a tubular, blind-ended secondary lymphoid organ located near the caecum, often referred to as the "tonsil of the abdomen" due to the abundance of lymphoid follicles in its histology. The presence of germinal centers, which are indicators of lymphatic tissue response to antigens and subsequent antibody production, helps assess the immune status of individuals. By counting these germinal centers, researchers can evaluate the immune status of the Bangladeshi population across different age and sex groups.

Variation of Antero-Posterior Diameter of Corpus Callosum in Different Age and Sex Groups of Bangladeshi People.

The corpus callosum (CC), the largest commissure of the brain, connects the two cerebral hemispheres and lies at the bottom of the longitudinal fissure. The antero-posterior diameter of the CC was larger in males than in females, but this difference was not significant. Again, the length of CC increased with age and there was also a positive significant correlation between the antero-posterior diameters of the CC with the antero-posterior diameter of the brain.

Variation of Length of Parieto-Occipital Sulcus in Different Age and Sex Groups of Bangladeshi People.

Parieto-occipital sulcus is one of the major sulcus of the cerebral hemisphere which separates the occipital lobe from the parietal lobe. Morphology of this sulcus varies with age, sex, manual skill, handedness and in many diseases. For various clinical investigations and surgery, detailed morphological knowledge of this sulcus is very much essential for the surgeons and radiologists.

Age Related Changes in the Purkinje Cells in Human Cerebellar Cortex in Bangladeshi People.

This study was done to see the changes in the number of Purkinje cells per square mm in different age groups of Bangladeshi people. This cross-sectional descriptive type of study was done on total 40 postmortem human cerebellums, in the Department of Anatomy, Mymensingh Medical College, Bangladesh from July 2016 to June 2017. The specimens were collected from morgue in the department of Forensic Medicine, Mymensingh Medical College, by purposive sampling technique.

Number and Diameter of White Pulp of Spleen in Different Age and Sex Groups of Bangladeshi People.

Spleen is a haemo-lymph organ and belongs to the reticuloendothelial system of human body, develops from mesodermal proliferation between the two leaves of dorsal mesogastrium. The microscopic structure of spleen is variable depending on the developmental stage of the organ, and the age and immune status of the individual. In our country, we depend on foreign data which came from the subjects of different races and from the individuals under different geographic conditions.
