Repolarization of the sarcolemma refers to the process of restoring the electrical charge across the muscle cell membrane following depolarization. It involves the movement of potassium ions out of the cell, returning the membrane potential to its resting state. This repolarization phase is critical for the muscle cell to prepare for its next contraction.
what is the plasma membrane of the muscle cell
The plasma membrane of a muscle fiber is called the sarcolemma. It surrounds the muscle cell and is responsible for controlling the passage of substances in and out of the cell, as well as transmitting signals for muscle contraction. The sarcolemma is essential for maintaining the integrity and function of the muscle fiber.
the sarcolemma encloses the muscle cell
the ventricular depolarization, which masks the atrial repolarization wave on the electrocardiogram. This is because the QRS complex is much larger than the atrial repolarization wave and overlaps with it, making it difficult to distinguish on the ECG.
The main ion responsible for depolarizing the sarcolemma is sodium (Na+).

No, the sarcolemma is the plasma membrane of a muscle cell.
The plasma membrane of a muscle fiber is called the sarcolemma. It surrounds the muscle cell and is responsible for controlling the passage of substances in and out of the cell, as well as transmitting signals for muscle contraction. The sarcolemma is essential for maintaining the integrity and function of the muscle fiber.
sarcomere and sarcolemma are two different things. a sarcomere is between two d zisks of a myofiber (muscle fiber). a sarcolemma is a plasma membrane. there are many sections of sarcomere under the layer of sarcolemma.
yes
The wave indicating atrial repolarization wave is hidden by the QRS complex. Ventricular repolarization is indicated by the T wave.
the sarcolemma encloses the muscle cell
Sarcolemma is defined as a thin membrane encasing a muscle fiber. This has no treatment as it is not an illness, injury or problem.
the ventricular depolarization, which masks the atrial repolarization wave on the electrocardiogram. This is because the QRS complex is much larger than the atrial repolarization wave and overlaps with it, making it difficult to distinguish on the ECG.
In the Sarcolemma
its called the plasma membrane or cell membrane. sometimes the semi-permeable plasma membrane. The Sarcolemma is the plasma membrane specifically surrounding a muscle fiber.
The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.
