Which of the following property is not related to skeletal muscle? 

Autorhthymicity is the property of conducting system of cardiac muscle.

Autorhythmicity refers to the ability of certain cells to generate spontaneous electrical impulses or action potentials without external neural or hormonal stimulation. In the context of muscle tissues, this property is primarily observed in the heart's specialised muscle cells, known as cardiac pacemaker cells or nodal cells.

In contrast, skeletal muscle does not possess inherent autorhythmicity. Skeletal muscle contractions are initiated by electrical signals sent from the nervous system through motor neurons. When these signals reach the neuromuscular junction (the point where the nerve meets the muscle), they trigger the release of acetylcholine, which stimulates the muscle fibers to contract.
