WebbSlow oxidative fibers have structural elements that maximize their ability to generate ATP through aerobic metabolism. These fibers contain many more mitochondria than the glycolytic fibers, as aerobic metabolism, which uses oxygen (O 2) in the metabolic pathway, occurs in the mitochondria. Webb12 okt. 2004 · The darkly stained fibers are relatively slow in contractile rate and are ST. These fibers demonstrate a higher aerobic (oxidative) capacity and a lower anaerobic (glycolytic) potential than the lighter stained FT fibers. Shorter's muscle contains approximately 80% ST fibers.

WebbUse the graph below to study how the speed of action potentials travel in different types of primary afferent nerve fibers. Action potentials in C-nerve fibers travel only about 2.2 mph - slower than you can walk. A … C fibers are one class of nerve fiber found in the nerves of the somatic sensory system. They are afferent fibers, conveying input signals from the periphery to the central nervous system. C fibers are unmyelinated unlike most other fibers in the nervous system. This lack of myelination is the cause of their slow conduction velocity, which is on the order of no more than 2 m/s. C fibers are on average 0.2-1.5 μm in diameter. sainsbury\u0027s email address for referencesWebb1 jan. 2014 · Definition.
