Is Autorhythmicity a Word?

The quality of being autorhythmic, or generating its own rhythm, as for example the cells of the cardiac muscle do.

What is Autorhythmicity of heart?

Automicity (Autorhythmicity) - some cardiac muscle cells are "self-excitable" allowing for rhythmic waves of contraction to adjacent cells throughout the heart. Skeletal muscle cells must be stimulated by independent motor neurons as part of a motor unit.

What is the role of Autorhythmicity?

Cardiac muscle tissue has autorhythmicity, the unique ability to initiate a cardiac action potential at a fixed rate – spreading the impulse rapidly from cell to cell to trigger the contraction of the entire heart. This autorhythmicity is still modulated by the endocrine and nervous systems.
