What does the Sarcolemma?

The sarcolemma is a specialized cell membrane which surrounds striated muscle fiber cells. Sometimes called the myolemma, the sarcolemma is similar to a typical plasma membrane but has specialized functions for the muscle cell.

Also question is, what is the function of a Sarcolemma?

Skeletal muscle, with sarcolemma labeled at upper left. The sarcolemma generally maintains the same function in muscle cells as the plasma membrane does in other eukaryote cells. It acts as a barrier between the extracellular and intracellular compartments, defining the individual muscle fiber from its surroundings.

Subsequently, question is, what is Sarcolemma and Sarcoplasm? The sarcolemma is a sheath enveloping myofibrils. The myofibrils, muscle fibres, are made up of sarcomeres, a group of myocytes (muscle cells) lined up in a strand giving muscles the striped look. Sarcoplasm is the specific type of cell plasma surrounding the sarcomeres that are contained within the sarcolemma.

Also, what does Sarcolemma mean?

Definition of sarcolemma. : the membrane enclosing a striated muscle fiber.

Is Sarcolemma present in smooth muscle?

The intermediate filaments are connected to other intermediate filaments via dense bodies, which eventually are attached to adherens junctions (also called focal adhesions) in the cell membrane of the smooth muscle cell, called the sarcolemma.
