Myocyte in smooth muscle
WebThe myocytes are surrounded by a rich network of blood vessels and capillaries and are embedded in a matrix of connective tissue. Also present in this matrix are nerves and lymphatics, as well as mast cells, histiocytes, fibroblasts, pericytes, and poorly differentiated mesenchymal cells. WebMyocytes are long, tubular cells. They develop from myoblasts to form muscles in a process called myogenesis. [2] There are various specialized forms of myocytes: cardiac, skeletal, and smooth muscle cells. They have different structures. The striated or striped cells of cardiac and skeletal muscles are called muscle fibers. [1]

They are bound together by perimysium, a sheath of connective tissue, into bundles called fascicles, which are in turn bundled together to form muscle tissue. WebMar 27, 2024 · In vascular and visceral smooth muscle cells the predominant α1 subunit of the channel is α1C (encoded by the CACNA1C gene) forming the Ca v 1.2 type calcium channel. However, in some smooth muscle types the α1D isoform (encoded by the CACNA1D gene) is also expressed forming the Ca v 1.3 type calcium channel. Within …
