lihassammenta
Lihassammenta, in human anatomy, refers to a muscle fascicle, a bundle of skeletal muscle fibers that functions as a structural and functional unit within a skeletal muscle. The term is Finnish for this concept, and it is surrounded by a connective tissue sheath called the perimysium. Each fascicle contains numerous muscle fibers, which are long, multinucleated cells rich in myofibrils.
The organization of a muscle includes three connective tissue layers. The epimysium surrounds the entire muscle,
Fascicles determine how a muscle converts neural signals into mechanical force. The orientation and distribution of
Developmentally, fascicles form as muscle tissue develops from mesodermal progenitors and differentiates into distinct fiber types
