Contractions and Relaxations: Each type of muscle is capable of contracting and relaxing, contributing to various physiological processes and bodily functions.

There are 3 types of muscle cells in the human body; cardiac, skeletal, and smooth. Skeletal muscle cells are long, cylindrical, multi-nucleated and striated . Each nucleus regulates the metabolic requirements of the sarcoplasm around it. Skeletal muscle cells have high energy requirements, so they contain many mitochondria in order to generate ...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 ).Exocytosis.

Skeletal muscle fibers possess intercalated discs. False. Creatine phosphate provides 30-40 seconds of energy for muscle activity. False.Troponin C (TnC) is a key regulatory protein in striated muscle contraction where its function is to bind Ca 2+, which subsequently triggers actomyosin interactions and initiates muscle contraction (Farah and Reinach, 1995). The TNNC1 gene expresses TnC in both cardiac and slow skeletal muscle (Song et al., 1996).Muscle is one of the four primary tissue types of the body (along with epithelial, nervous, and connective tissues), and the body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle (Figure 24.1).All three muscle tissues have some properties in common; they all exhibit a quality called excitability as their plasma membranes can change their electrical ...

Striation is also visible in cardiac muscles, but not as clearly.Troponin C (TnC) is a key regulatory protein in striated muscle contraction where its function is to bind Ca 2+, which subsequently triggers actomyosin interactions and initiates muscle contraction (Farah and Reinach, 1995). The TNNC1 gene expresses TnC in both cardiac and slow skeletal muscle (Song et al., 1996).striations Since both cardiac and skeletal muscles possess arrangements of motor proteins in regularly arrayed sarcomeres, they both display the banding known as striations.

A. possess striations. A fasciculus A. is a bundle of reticular fibers. B. is surrounded by perimysium. C. is only found in smooth muscle.Inside each skeletal muscle, muscle fibers are organized into individual bundles, each called a fascicle, by a middle layer of connective tissue called the perimysium.This fascicular organization is common in muscles of the limbs; it allows the nervous system to trigger a specific movement of a muscle by activating a subset of muscle fibers within a bundle, or fascicle of the muscle.The Dystrophin Complex. The dystrophin-glycoprotein complex (DGC) is a multi-subunit complex within and across the membranes of cardiac and skeletal muscle cells as well as vascular smooth muscle cells. The complex serves both a mechanical stabilizing and a signaling role in these various cell types.Cardiac muscle is different from skeletal muscle in that the muscle is branching, with intercalated dicks at the ends of them, store less calcium, the transverse tubules are larger, and their ...Striated muscles are most clearly found in skeletal muscles (they are voluntary!), where sarcomeres are used to contract and relax the tissue. Striation is also visible in cardiac muscles, but not as clearly.Cardiac muscle contains a great many mitochondria, which produce ATP for energy. This helps the heart resist fatigue. Contractions of cardiac muscle are involuntary, like those of smooth muscle. Cardiac muscle, like skeletal muscle, is arranged in bundles, so it appears striated, or striped.See Answer.

Recall that cardiac muscle shares a few characteristics with both skeletal muscle and smooth muscle, but it has some unique properties of its own.In 1510, Leonardo Da Vinci was the first to describe the heart muscle as arranged in longitudinal and transverse fibers and their contraction resulted in shortening and widening of the ventricular cavities. 1 Since then, there has been a divergence in the study of cardiac and skeletal muscle cells because of the complexity in structure and function of cardiac myocytes.Cardiac muscle, found in the walls of the heart, is also under control of the autonomic nervous system. The cardiac muscle cell has one central nucleus, like smooth muscle, but it also is striated, like skeletal muscle. The cardiac muscle cell is rectangular in shape. The contraction of cardiac muscle is involuntary, strong, and rhythmical.This causes the nerve cell to release acetylcholine (Ach) into the muscle cell.-The muscle cell responds to the acetylcholine (Ach) by having AP.-The muscle cell AP travels over the muscle cell membrane and down the t-tubules and causes Ca2+ to be released from the sarcoplasmic reticulum. This floods the inside of the muscle cell with Ca2+ ions.Coming to the question, 1. Striated muscles are called voluntary muscles because they work on our own will . They get tired easily. 2. Striated muscles are attached to bones and help in the movement of body parts. So, they are called skeletal muscles as bones form skeleton which have striated muscles attached to them.These proteins are the same in both skeletal and cardiac muscle. Function of Cardiac Muscle. As in skeletal muscle, the signal to contract is an action potential. However with skeletal muscle this signal usually comes from the somatic, or voluntary, nervous system. Cardiac muscle is controlled by the autonomous nervous system. Cells …Cardiac and skeletal muscle both possess striations. true Cardiac muscle fibers are joined by special gap junctions called intercalated discs; these discs allow heart activity to be closely coordinated.

Differences between cardiac and skeletal muscle. Although cardiac myocytes are striated with sarcomeres of very similar composition to those of skeletal muscle, there are important structural and functional differences between the two muscle types. The most obvious difference is the size of the cells., Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres. The presence of sarcomeres manifests as a series of bands visible along the muscle fibers, which is responsible for the striated appearance observed in microscopic images of this tissue.
