Human skeletal muscles can be further categorized into slow-oxidative/Type I, fast-oxidative/Type IIa, and fast-glycolytic/Type IIb types based on their contractile and metabolic phenotypes [].Striated muscles are required for whole-body oxygen supply, metabolic balance, and locomotion.

There are three major types of muscle, and their structure reflects their function. Skeletal and cardiac muscle cells are called striated muscle because of the very regular arrangement of their intracellular contractile units, sarcomeres, at the light microscope (LM) and electron microscope (EM) levels. This regular arrangement imparts a cross-striated (or striped) appearance.The other two types are skeletal muscle tissue and smooth muscle tissue.

In skeletal muscle, the excitation-contraction (EC) coupling machinery mediates the translation of the action potential transmitted by the nerve into intracellular calcium release and muscle contraction. EC coupling requires a highly specialized membranous structure, the triad, composed of a central T-tubule surrounded by two terminal cisternae from the sarcoplasmic reticulum. While several ...The statement is True. Both cardiac and skeletal muscles possess striations. Explanation Muscle tissue in the body is of three types: skeletal, cardiac, and smooth.Striated muscles—skeletal and cardiac muscle—differ in terms of the number and position of nuclei. In humans, skeletal muscle fibers are syncytia and their nuclei are peripheral ( Allbrook, 1962 ), while cardiomyocytes are mononucleated (even though they are tetraploid) and this nucleus is central ( Adler, 1975 ; Kikuchi and Poss, 2012 ).Skeletal muscle, as the name implies, is any muscles that connects to and controls the motions of the skeleton. In all there are somewhere between 600 and 900 muscles in the human body, but an exact number is hard. Many muscles are obscurely small or are sometimes grouped together with similar muscles.Compared to the giant cylinders of skeletal muscle, cardiac muscle cells, or cardiomyocytes, are considerably shorter with much smaller diameters.

These myosin isoforms are transiently expressed during embryonic and fetal development and disappear shortly after ...

A sarcomere is the basic unit of muscle tissue in both cardiac and skeletal muscle. Sarcomeres appear under the microscope as striations, with alternating dark and light bands. Sarcomeres are connected to a plasma membrane, called a sarcolemma, by T-tubules, which speed up the rate of depolarization within the sarcomere.

It is striated, branched, and contains intercalated discs. Explanation: Cardiac muscle tissue is found in the heart and is responsible for pumping blood throughout the body. It is striated, branched, and contains intercalated discs, which help coordinate contractions.

This article will consider the structure of cardiac muscle as well as relevant clinical conditions.Cardiac muscle fibers cells also are extensively branched and are connected to one another at their ends by intercalated discs.
