What is rhythmical contraction?
RHYTHMICAL. CONTRACTION. Among the numerous muscle fibers present in the growth in a tissue culture, one may occasionally contract rhythmically. The time interval of the rhythmical contraction has been different for each muscle fiber as well as for each myoblast that has so far been observed to contract.
Does smooth muscle have rhythmic contractions?
Spontaneous, rhythmical contractions are generated in many different types of smooth muscle, from the gastrointestinal tract, urinary tract and lymphatic vessels through to arteries and veins (Tomita, 1981; Van Helden, 1993; Hashitani et al. 1996).
Which type of muscle is found in the body wall of hollow organs?
Smooth muscle fibers
Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines), except the heart, appear spindle-shaped, and are also under involuntary control. Skeletal muscle fibers occur in muscles which are attached to the skeleton.

Which muscles can show rhythmic contraction?
Skeletal muscles/cardiac muscles show rhythmic contraction.
What is responsible for the rhythmic contractions of the heart?
The rhythmic contraction of cardiac muscle is regulated by the sinoatrial node of the heart, which serves as the heart’s pacemaker.
What is the contractile unit of a muscle called?
The sarcomere of striated muscles. Depicted in Figure 1 is the sarcomere, which is the basic contractile unit of striated muscle. Sarcomeres are organized in series to make up a myofibril.
