“Sarcolemma” is the name given to the cell membrane of myocytes (also known as muscle cells). Although the sarcolemma is similar to other cell membranes, it has other functions that set it apart. For instance, the sarcolemma transmits synaptic signals, helps generate action potentials, and is very involved in muscle contractions. Unlike other cell membranes, the sarcolemma makes up small channels called “t-tubules” that pass through the entirety of muscle cells. It has also been found that the average sarcolemma is 10 m thick as opposed to the 4 m thickness of a general cell membrane.
