Vermiform appendix varies in length from 2-20cm (Gupta et al,. 2012). Many changes in the structure of this organ may occur with aging among that good thickness, shortening, and atrophy of the muscular coat (Eliseev,1979). Lymphoid involution was observed in many studies (Eliseev,1979; Shcherbakov,1980). In the past vermiform appendix was considered as unimportant part, but then after, they found that it is not a useless part in humans (Zahid, 2004).

The Journal is an Egyptian journal covering the whole field of general, experimental, systematic and applied entomology. Manuscripts generally should not exceed 30 pages (exceptions are possible, particularly in case of reviews, and should be negotiated in advance with the editors). Papers are considered by referees before acceptance. Authors will receive first editorial decision within 8 weeks from confirmed submission. All contributions are published in English. Authors whose mother tongue is not English are strongly urged to have their manuscripts reviewed linguistically before submission. Papers written in poor English will be returned. It is understood that manuscripts submitted to EAJBS have not been offered to any other journal for prior or simultaneous publication. http://eajbsd.journals.ekb.eg/ Provided for non-commercial research and education use.

It is characterized by a large number of lymphoid tissues. The important feature of this structure at a young age is the presence of large and numerous lymphoid follicles in both layers of mucosa and submucosa. Objective: The aim of the present investigation was to find out the age and sex-related changes among adult Iraqi vermiform appendix anatomically. Materials & methods:Fifty normal human cadavers were selected. Of the total number of cadavers, 30 males and 20 females were included. All the cadavers were divided into age groups. For each cadaver, weight, length, and width were measured. Results: appendix weight in males was higher than females for all age groups. The length of the appendix was also more in males than in females. External diameter varied from the base towards the tip. The diameter of the base was higher in the middle and the tip regions. These values were more in males than in females. Conclusion: The weight, length, and diameter of the vermiform appendix in males were more than in females. The diameter of the appendix is more at the base than at the middle and the tip regions.
