Nephritis is the most common cause of blood in the urine of children and young adults but it can occur at any age. If your GP suspects nephritis he will usually refer you to a nephrologist (kidney doctor).
Muscle fiber types can be broken down into two main types: slow twitch (Type I) muscle fibers and fast twitch (Type II) muscle fibers. These fast twitch fibers can be further categorized into Type IIa and Type IIb fibers, which are also known as fast twitch oxidative and fast twitch glycolytic, respectively.
In contrast with A and B fibers, C fibers have the smallest diameter (.4mm to 1.3mm), conduction (.5-2.3m/sec) and are unmyelinated. The two types of C fibers are Dorsal root and Sympathetic. 1. Dorsal root fibers serve the modality of pain, warm and cold temperature, and touch. 2.The sympathetic type involves postganglionic sympathetic fibers. The pain produced by C fibers is characterizized as dull, often poorly localized and slower onset.he two types of C fibers are Dorsal root and Sympathetic. 1.
