Leiomyocyte

Leiomyocytes are the main elements of skeletal muscle and smooth muscle. They play a key role in regulating muscle tone, contraction and relaxation. Leiomyocytes are of two types: primary and secondary. Primary leiomyocytes are mature cells that begin to contract only when exposed to various factors. For example, when performing physical exercise or in response to nerve signals from motor neurons. Unlike primary leiomyocytes, secondary leiomyocytes are capable of generating tension and movement without stimulation. They contain specialized membrane channels and pumps that allow them to actively accumulate various substances. For example, Ca++ or H+. Thanks to this, they can contract even in the absence of excitatory signals from motor neurons, as happens in the vascular system or the bladder. Skeletal and cardiac muscles are characterized by fibrillar type of muscle fibers, and smooth muscles are characterized by

Leiomyocytes are cells that form the muscle tissue of the heart, lungs, intestines, uterus and other organs. These cells have the ability to contract, which allows movement and control of blood flow in the body. Leiomyocytes are also called smooth muscles.
