Which descriptions are true regarding different muscle types? check all that apply. cardiac and skeletal muscles are striated. skeletal and smooth muscles are nonstriated. smooth and cardiac muscles are voluntary. heart and digestive muscles are involuntary muscles. smooth and skeletal muscles are involved in movement. cardiac muscles work to pump blood?

The true descriptions regarding muscles are; Cardiac muscles and skeletal muscles are striated, heart (cardiac) and digestive (smooth) muscles are involuntary muscles, cardiac muscles work to pump blood. Skeletal muscles are the muscles that attach to the bones and their main function i contracting to facilitate movement of our skeletons. Smooth muscle are found in walls of hollow organs such as the stomach and are stimulated by involuntary action. While the cardiac muscles are found solely in the walls of the heart, they are highly specialized and under the control of of the autonomic nervous system.

The smooth, skeletal, and heart muscles compose the muscular system. Correct options: 1)cardiac and skeletal muscles are striated. 4)Heart and digestive muscles are involuntary muscles. 6) Cardiac muscles work to pump blood.  

The muscular system is composed of all muscles in the body. Muscles are made of myocytes.

The principal muscles' function is to move different parts, voluntarily or involuntarily, creating equilibrium.

There are three types of muscles: smooth muscle,  skeletal muscle, and myocardium.

The smooth muscle It is formed by fusiform cells, mononucleated, and with no transversal striations. There is a protein contraction system, but not as organized as the skeletal muscle's one. Smooth-muscle is located in different organs, vessels, veins, and arteries. It provides sustained contractions, slow and rhythmical, but not voluntary. The skeletal muscle It is the most abundant muscle in vertebrates, constituting the somatic musculature. Among its many functions, it proportionates motion to extremities and digits and is responsible for the position and posture of the individual. It also participates in eye movements, respiration, mastication, deglutition, and phonation.The skeletal muscle contracts voluntarily, and its response is fast. Cells composing the striated muscle are significantly longer and multinucleated. They arrange in bundles, where cells are parallel to each other. Myocardium muscleThis tissue resembles more to the striated tissue than to the smooth one. However, there are some differences between them. Cardiac cells are cylindrical and shorter, with ramifications. Cardiac cells have one nucleus, and occasionally there can be two.
