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.
The sciatic nerve branches into the tibial and common peroneal nerves in the apex of the popliteal fossa. The common peroneal nerve winds around the proximal neck of the fibula to reach the anterior leg where it divides into the superficial and deep peroneal nerves. peripheral nerve that contains axons of the autonomic nervous system, either transmitting afferent signals from mucous membranes, glands, and vessels (visceral sensory nerves) or transmitting efferent signals to smooth muscles and glands (visceral motor nerves).
