Summary
This study examined the vermiform appendix lumen diameter in Bangladeshi individuals. Females generally exhibited a slightly larger mean luminal diameter compared to males across different age groups.
Area of Science:
- Anatomy
- Histology
- Forensic Medicine
Background:
- The vermiform appendix is a vestigial organ with potential roles in immunity and gut microbiota.
- Understanding its morphometric variations is crucial for anatomical and clinical contexts.
Purpose of the Study:
- To determine the histomorphometry of the vermiform appendix lumen in a Bangladeshi population.
- To investigate potential differences in luminal diameter based on age and sex.
Main Methods:
- A cross-sectional descriptive study involving 100 fresh vermiform appendix specimens.
- Specimens were collected during postmortem examinations at Mymensingh Medical College.
- Luminal diameter measurements were categorized into four age groups (A: up to 20 years, B: 21-35, C: 36-55, D: 56-70 years).
Main Results:
- The mean luminal diameter of the vermiform appendix was slightly greater in females (60.71 μm) than in males (60.11 μm).
- Maximum diameter was observed in Group A females (87.00 μm), and the minimum diameter was found in Group B females (4.70 μm).
Conclusions:
- This study provides baseline histomorphometric data for the Bangladeshi population.
- Age and sex appear to influence vermiform appendix luminal diameter, with females showing a marginally larger mean diameter.

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:26Histology of the Large Intestine
The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

01:27Histology of the Small Intestine
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

01:16Gross Anatomy of the Stomach
The human stomach is a vital part of the digestive system, performing multiple functions. It is located within the peritoneum, a serous membrane that lines the abdominal cavity. The stomach plays a central role in processing food substances and interacts with other digestive organs through coordinated digestive processes. The stomach has a characteristic J-shape and is divided into four main regions. The cardia is the first section where the esophagus connects to the stomach and is the entry...
01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

01:23Anatomy of the Intestines
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...
