Muscle cell - Wikipedia
网页A muscle cell, also known as a myocyte, is a mature contractile cell in the muscle of an animal. [1] . In humans and other vertebrates there are three types: skeletal, smooth, and cardiac (cardiomyocytes). [2] . A skeletal muscle cell is long and threadlike with many nuclei and is called a muscle fiber. [3] .
Muscle Cell (Myocyte): Definition, Function & Structure | Biology
网页2019年10月4日 · A muscle cell, known technically as a myocyte, is a specialized animal cell which can shorten its length using a series of motor proteins specially arranged within the cell. While several associated proteins help, actin and myosin form thick and thin filaments which slide past each other to contract small units of a muscle cell.
