Smooth Muscle - Definition, Function and Location | Biology
2019年10月4日 · Smooth muscle is composed of sheets or strands of smooth muscle cells. These cells have fibers of actin and myosin which run through the cell and are supported by a framework of other proteins. Smooth muscle contracts under certain stimuli as ATP is freed for use by the myosin.

2023年8月14日 · Smooth muscle derives from both mesoderm and neural crest cells; this is because smooth muscle contributes to many different tissues throughout the body. One unique feature of neural crest cells is that their migration occurs during embryological development.
Smooth muscle - Wikipedia
A smooth-muscle cell is a spindle-shaped myocyte with a wide middle and tapering ends, and a single nucleus. Like striated muscle, smooth muscle can tense and relax. In the relaxed state, each cell is 30–200 micrometers in length, some thousands of times shorter than a …

2023年7月17日 · Smooth muscle consists of two types single-unit and multi-unit. Single-unit smooth muscle consists of multiple cells connected through connexins that can be stimulated in a synchronous pattern from only one synaptic input. Connexins allow for cell-to-cell communication between groups of single-unit smooth muscle cells.
10.7 Smooth Muscle Tissue – Anatomy & Physiology
Smooth muscle is found throughout the body around various organs and tracts. Smooth muscle cells have a single nucleus, and are spindle-shaped. Smooth muscle cells can undergo hyperplasia, mitotically dividing to produce new cells.

2024年4月9日 · Smooth muscle is one of three types of muscle tissue, alongside cardiac and skeletal muscle. It is a non-striated muscle tissue, lacking the characteristic markings of the other muscle types. It is found in numerous bodily systems, including the ophthalmic, reproductive, respiratory and gastrointestinal systems, where it functions to contract ...
