Summary
The lengths of the main pancreatic duct (MPD) and submandibular duct (SMD) correlate, but other ductal features do not. This suggests a complex relationship between these digestive glands.
Area of Science:
- Anatomy
- Digestive System Physiology
- Medical Imaging
Background:
- Investigating ductal morphometry and ramification patterns in the submandibular gland and pancreas.
- Validating a common fractal dimension for these glands.
Purpose of the Study:
- To evaluate the relationship between ductal morphometry and ramification patterns in the submandibular gland and pancreas.
- To validate their common fractal dimension.
Main Methods:
- X-ray ductography with software-aided morphometry.
- Barium sulphate injection into ducts of 42 post-mortem adult submandibular glands and pancreases.
Main Results:
- Significant correlation found between the length of the main pancreatic duct (MPD) and both right and left submandibular ducts (SMD).
- Maximal diameters of MPD and SMD did not correlate.
- Number of MPD side branches correlated with the left SMD, but not the right. Tortuosity was observed in MPD, right SMD, and left SMD.
Conclusions:
- Intraglandular length of SMD and MPD correlate.
- Other morphometric ductal features do not show correlation, indicating a complex relationship between the two glands.

The pancreas, an essential organ in the human body, is a pinkish-gray elongated structure located posterior to the stomach. It extends laterally from the duodenum towards the spleen and is firmly bound to the posterior wall of the abdominal cavity. The organ's surface has a lumpy, lobular texture that gives it a unique appearance.
The broad head of the pancreas lies within the loop formed by the duodenum, while its slender body reaches towards the spleen. The tail of the pancreas is short...

917
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...
