Seroma â Definition, Symptoms, Fluid, Treatment, Types. A Seroma is a collection of serous fluid that develops after surgery or any blunt injury. Serous fluid is the fluid compartment of blood that seeps out when blood vessels are injured or ruptured during operation. Inflammation on the surgical site also increases the capillary permeability, thus increasing the flow of plasma from blood vessels into the interstitial spaces (spaces between cells).
A detailed description of the anatomical variations of the median nerve in the carpal tunnel, including the bifid median nerve, was previously reported. The bifid median nerve is a cause of secondary carpal tunnel syndrome due to its relatively higher cross-sectional area compared with a nonbifid median nerve. Magnetic resonance imaging (MRI) and ultrasound can be obtained to show bifid median nerves, helping surgeons avoid potential surgical hazards.
Vagus Nerve. The vagus nerve is the tenth cranial nerve (CN X) and is responsible for parasymapthetic nerve supply to the stomach. It enters the abdomen through the esophageal hiatus in the diaphragm. The anterior vagal trunk supplies the anterior aspect (front) of the stomach and is derived from the left vagus nerve. The posterior vagal trunk supplies the posterior aspect (back) of the stomach and to a lesser extent the anterior aspect of the stomach and is derived from the right vagus nerve.
