1) Skeletal muscle: moves the skeleton, voluntary movements, multinucleated cells. 2) Cardiac muscle: connected by intercalated discs, nucleus surrounded by glycogen. 3) Smooth muscle: propel contents through a tubular organ, mostly found in viscera.
What are the different types of muscles?
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.
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.
This 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.
