[Answer] What type of muscle exhibits autorhythmicity (beats with a steady rhythm)?

Answer: cardiac
What type of muscle exhibits autorhythmicity (beats with a steady rhythm)?

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.. There are two types of cardiac muscle cell: cardiomyocytes which have the ability to contract easily …

The cardiac action potential is a brief change in voltage (membrane potential) across the cell membrane of heart cells. This is caused by the movement of charged atoms (called ions) between the inside and outside of the cell through proteins called ion channels.The cardiac action potential differs from action potentials found in other types of electrically excitable cells such as nerves.

Heart cells exhibit automaticity the ability to generate electrical activity independent of external stimulation. The electrical activity spontaneously generated by the …

The heart is a muscular organ in most animals which pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body while carrying metabolic waste such as carbon dioxide to the lungs. In humans the heart is approximately the size of a closed fist and is located between the lungs in the middle compartment of the chest.

Muscle contraction is the activation of te…
