Sarcolemma - Wikipedia
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.
Sarcolemma - Definition and Function - Biology Dictionary
2017年4月28日 · 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.

2022年6月16日 · 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 …
Sarcolemma | Complete Anatomy - Elsevier
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.
Sarcolemma | anatomy | Britannica
…a muscle cell, called the sarcolemma, separates the sarcoplasm (muscle cell cytoplasm) from the extracellular surroundings. Within the sarcoplasm of each individual muscle fibre are approximately 1,000 to 2,000 myofibrils.
Sarcolemma - an overview | ScienceDirect Topics
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.
Sarcolemma - an overview | ScienceDirect Topics
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
Sarcolemma - an overview | ScienceDirect Topics
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 ...
Sarcolemma: Key Player in Muscle Function and Communication
2024年10月20日 · 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.
