Background: Many works have been carried out related to the worm-like vermiform appendix in humans. 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.
