Apr 28, 2017 · 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.

The sarcolemma (sarco (from sarx) from Greek; flesh, and lemma from Greek; sheath), also called the myolemma, is the cell membrane surrounding a skeletal muscle fibre or a cardiomyocyte. [1] [2] It consists of a lipid bilayer and a thin outer coat of polysaccharide material that contacts the basement membrane.

Jun 16, 2022 · What is the sarcolemma? It is the thin, transparent, extensible plasma membrane of the muscle cell. It consists of a cell membrane (plasma membrane) and an outer coat made up of a thin layer of polysaccharide ( glycocalyx ) material with numerous thin collagen fibrils.

The sarcolemma is the fine, delicate, extensible membrane surrounding each muscle fiber. It is composed of a cell, or plasma, membrane which presents an extracellular matrix of collagen fibrils and polysaccharides that make contact with the basal lamina.

The sarcolemma is defined as the membrane surrounding muscle fibers, exhibiting excitability to transmit electrical impulses and containing proteins for various functions like transport and enzyme activity.

Oct 20, 2024 · Explore how the sarcolemma facilitates muscle function and communication through its structure, ion channels, and interaction with the cytoskeleton. Muscle function relies heavily on the sarcolemma, a specialized cell membrane that envelops muscle fibers.

The meaning of SARCOLEMMA is the membrane enclosing a striated muscle fiber.

The sarcolemma is the specialized cell membrane of cardiomyocytes. It contains a multitude of muscle-specific and ubiquitously expressed membrane proteins that anchor the cytoskeleton and sarcomere to the surrounding extracellular matrix (ECM), allowing for the regulated exchange of ions and nutrients, as well as the activation of biomechanical ...

The sarcolemma is a lipid bilayer that is not uniform but rather separated into distinct membrane microdomains. From: Ion Channels in Health and Disease, 2016
