Sarcolemma - Wikipedia, the free encyclopedia
The sarcolemma is the cell membrane of a muscle cell (skeletal, cardiac and smooth muscle). It consists of a true cell membrane, called the plasma membrane, and an outer coat made up of a thin layer...

A T-tubule is a deep invagination of the sarcolemma, which is the plasmamembrane, only found in skeletal and cardiac musclecells. These invaginations allow depolarizationof the membrane to quickly penetrate to the interior of the cell.

As the electrochemical potential of Ca2+ across the sarcolemma would prevent its passive outflow, the efflux of Ca2+ is an energy requiring process. Most of the Ca2+ is apparently ejected from heart cells in exchange for Na+ (refs 7, 8), on an electrophoretic antiporter which exchanges three Na+ ions for one Ca2+ (ref.

We show that MCSP/NG2 expression is detectable in the sarcolemma, and in the neuromuscular junction of human postnatal skeletal muscle, and it gradually reduces with advancing age. In human and murine myogenic cell lines, we found no clear differences in MCSP/NG2 expression between myoblasts and myotubes.
