Cutaneous leiomyomas are rare, benign, smooth muscle tumors that are subcategorized based on the origin of the smooth muscle within the tumor. The most common type of cutaneous leiomyomas, angioleiomyomas, arise from the tunica media of blood vessels. The 2 other subtypes, piloleiomyomas and genital leiomyomas, arise from the arrector pili musculature of the hair follicle and from the smooth ...

Smooth Muscle Definition. Smooth muscle is a type of muscle tissue which is used by various systems to apply pressure to vessels and organs. 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.In fact, it is known that nuclei in different positions of the myofibers have different functions and express different genes (Newlands et al., 1998). scRNA-seq and mass cytometry studies have defined the major mononuclear cell types present in skeletal muscle: fibroadipogenic progenitors (FAPs), tenocytes, endothelial cells, smooth muscle ...Having a six pack is almost every guy’s dream.
