What are the different types of skeletal muscles?
There are three types of muscles in the body - smooth, heart and skeletal muscles. The muscles are placed in one of the three categories based on their structure and function. The heart muscle is only in the heart, while smooth - or involuntary - is located around organs and is not under conscious control. The skeletal muscles are thus named because they connect to the skeleton. They are under voluntary control, but there are different types of skeletal muscles. Skeletal muscles support the skeleton and also move it through contracts and relaxation of various muscles. Different types of skeletal muscles are often grouped on whether they are downloading quickly or slowly. Type I fibers are also referred to as slow jerking or slow oxidation muscles. These types of muscles are withdrawing more slowly than the II muscles. They are red and contain a large amount of mitochondria in their cells. The type I fibers are mainly made of myoglobin and have many capillaries throughout the muscle.
To contraction of muscles, cells need energy. This energy is produced by the distribution of adenosine triphosphate (ATP) molecules. The measure at which the distribution of ATP will affect how quickly or slowly the muscle can download. Type i fibers divide ATP much more slow than II fibers. The process of distributing and regeneration of ATP in type I fibers uses oxygen and the muscles take longer to get tired.
Fiberstype II can be divided further into different types of skeletal muscles. Both groups of type II fibers are rapid fibers twitching, but differ in other functional and structural ways. Type II fibers look similar to the type of type of type in that they have a red color, contain a large amount of myoglobin and have many mitochondria and capillaries. Unlike type 1 fibers, however, type II ATP fibers were divided very quickly, so they download rapidly. These types of skeletal muscles rarely occur in humans.
type II B fibers are another category of skeletal muscles of rapid jerk.Unlike type I and type II fibers, they contain small myoglobin and several mitochondria and have several capillaries. They contain high levels of glycogen. These fibers look white in the color distribution of ATP quickly to download quickly. The ATP distribution process in these muscle fibers is anaerobic or does not require oxygen, so it cannot be prolonged and the muscles are relatively quickly tired.
