What is the plasma membrane of the muscle fiber?
Sarcolemma
What is a cell membrane of a muscle fiber called?
what is the plasma membrane of the muscle cell
Atrial repolarization coincides in time with?
Atrial repolarization coincides with the QRS complex on the ECG. The T-wave corresponds to Ventricular repolarization. 'with tHE t-wave' <-- WRONG
Irregular transverse thickenings of the sarcolemma?
Irregular transverse thickenings of the sarcolemma connect cardiac muscle fibers to neighboring muscle fibers. The gap junctions that occur with irregular transverse thickening of the sarcolemma allow the myocardium to contract as a single unit.
When the chemically gated ion channels open which ion is mainly responsible for depolarizing the sarcolemma?
The main ion responsible for depolarizing the sarcolemma is sodium (Na+).
What is the plasma membrane of the muscle fiber?
Sarcolemma
What is a cell membrane of a muscle fiber called?
what is the plasma membrane of the muscle cell
Is sarcolemma a ligament?
No, the sarcolemma is the plasma membrane of a muscle cell.
Is Sarcomere and sarcolemma the same thing?
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.
Repolarization of a ventricular cardiocyte taks longer then repolarization of a typical neuron?
yes
What is the difference between endomysium and sarcolemma?
Sarcolemma is the equivalent of the plasma membrane of the muscle fiber (aka muscle cell). The endomysium is a connective tissue that bounds around the sarcolemma.
What is the portion of the ECG that indicates ventricular repolarization?
The wave indicating atrial repolarization wave is hidden by the QRS complex. Ventricular repolarization is indicated by the T wave.
Atrial repolarization coincides in time with?
Atrial repolarization coincides with the QRS complex on the ECG. The T-wave corresponds to Ventricular repolarization. 'with tHE t-wave' <-- WRONG
What connects the sarcolemma and the sarcoplasmic reticulum?
They connect to the transverse tubules of the the sarcolemma at triad junctions.
What is the treatment for sarcolemma?
Sarcolemma is defined as a thin membrane encasing a muscle fiber. This has no treatment as it is not an illness, injury or problem.
What is atrial repolarization indicated by?
The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.
Where are acetycholine receptors found?
In the Sarcolemma
