Not exclusively:
Cardiac Muscle cells are either contractile cells or autorhythmic cells. The majority are contractile.
Examples of autorhythmic cells:
Sinoatrial (SA), or Sinus, Node
Atrioventricular (AV) Node
Atrioventricular (AV) Bundle (occasionally referred to as the bundle of His)
Right and Left Bundle Branches
Purkinje Fibers
What else can I help you with?
How do the waves of depolarization generated by the autorhythmic cells spread to the muscle cells?
Autorhythmic cells in the heart generate electrical impulses that spread through the atria and ventricles via specialized conduction pathways, such as the atrioventricular node, bundle of His, and Purkinje fibers. These pathways allow for coordinated depolarization of the muscle cells, ultimately leading to contraction of the heart chambers.
Where are bipolar amacrine and ganglion cells located?
Bipolar cells are located in the inner nuclear layer of the retina, while amacrine cells are found in the inner plexiform layer. Ganglion cells are located in the ganglion cell layer, which is the innermost layer of the retina.
Where are T cells located within lymph nodes?
T cells are located in the paracortex region of lymph nodes.
Where are the epidermal cells of an onion located?
The epidermal cells of an onion are located on the outermost layer of the onion bulb, forming a protective barrier.
Where in the onion plants are the green cells located?
The green cells in an onion plant are located in the leaves. These cells contain chlorophyll, which is responsible for photosynthesis and gives the leaves their green color.

What does auto-rhythmic mean?
Autorhythmic cells (pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.
What does auto rhythmic mean?
Autorhythmic cells (pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.
Are SA nodal cells autorhythmic?
Yes, sinoatrial (SA) nodal cells are autorhythmic, meaning they can generate electrical impulses spontaneously without external stimulation. This property is due to their unique ion channel composition, which allows for gradual depolarization during the diastolic phase. As a result, the SA node serves as the primary pacemaker of the heart, initiating the heartbeat and regulating the heart rate.
Where are autorhythmic cells located in the heart?
There are two pacemakers in the heart. One (which is the main pacemaker of the heart) can be found in the upper right-most part of the right atrium and the other one can be found in the center most part of the heart, inside the atrio-ventricular wall.
What does it means when cardiac cells are connective and autorhythmic?
When cardiac cells are described as connective, it means they are interconnected through specialized junctions called intercalated discs, which allow for coordinated contractions and efficient electrical signal transmission throughout the heart. Being autorhythmic refers to their ability to generate electrical impulses spontaneously, enabling the heart to maintain a regular rhythm without external stimulation. Together, these properties ensure that the heart can contract effectively and rhythmically, facilitating continuous blood circulation.
Does blood clott in anterior interventricular branch causes sudden death?
A blood clot, also called a thrombus, in the anterior interventricular branch causes sudden death. This branch supplies the majority of blood to the walls of both ventricles. The presence of a thrombus can block the bloodflow to heart muscle cells, causing instant death.
Where Are the Stinging Cells of a Jellyfish Located?
The stinging cells in a jellyfish are located in it's tentacles.
What cells are centrioles located in?
animal cells
Where is mitrochrodria located in a animals cells?
in the cells
What neuroglial cell is located in the peripheral nervous system?
Schwann cells and satellite cells are neuroglial cells located in the PNS
what are palisade cells?
Palisade cells are plant cells located on the leaves
