The property of self-vibration is found in any of the following muscles:

The property of self-vibration, also known as automaticity, is found in the (a) Heart muscle. The heart possesses its intrinsic electrical conduction system, which initiates and coordinates rhythmic contractions without external stimulation. This unique property enables the heart to generate its rhythmic heartbeat, essential for pumping blood throughout the body and maintaining circulation.

Unlike skeletal muscles, which require external stimuli from nerves to contract, cardiac muscle cells can spontaneously depolarize and generate action potentials. This ability is crucial for the heart’s function as a pump, ensuring that it continues to beat even in the absence of neural input.

While other organs such as the kidney, liver, and intestine have muscle tissue, they do not possess the same inherent property of self-vibration or automaticity. Instead, their muscular activity is typically regulated by the autonomic nervous system or influenced by hormonal signals in response to physiological needs such as digestion, filtration, and detoxification.
