yes
The organelle that is a bundle of contractile elements is called a?
Myofibris are cylindrical organelle. It is the organelle that is a bundle of contractile elements. Contractility is the ability to shorten forcibly when adequately stimulated.
What is the function of the bundle of HIS?
The bundle of HIS is responsible for conducting electrical signals from the atria to the ventricles in the heart. This pathway allows for coordinated contraction of the heart chambers, ensuring efficient blood pumping.
What is a myofibril?
A myofibril is a bundle of contractile filaments (myofilaments), 1-2 μm in diameter, that are arranged in parallel groups in the cytoplasm of striated muscle cells.
Are autorhythmic cells located only in the interventricular septume?
Not exclusively:Cardiac Muscle cells are either contractile cells or autorhythmic cells. The majority are contractile.Examples of autorhythmic cells:Sinoatrial (SA), or Sinus, NodeAtrioventricular (AV) NodeAtrioventricular (AV) Bundle (occasionally referred to as the bundle of His)Right and Left Bundle BranchesPurkinje Fibers
What are the Fibers of ventricular bundle?
The fibers of the ventricular bundle, also known as the bundle of His, are specialized cardiac muscle fibers that conduct electrical impulses from the atrioventricular (AV) node to the Purkinje fibers in the ventricles. These fibers play a critical role in coordinating the contraction of the ventricles during the cardiac cycle, ensuring effective pumping of blood out of the heart.
