What muscles are smooth muscles

Smooth muscle: Along with skeletal and cardiac muscle, one of the types of muscle tissue in the body. Smooth muscle generally forms the supporting tissue of blood vessels and hollow internal organs, such as the stomach, intestine, and bladder.

What are smooth muscle and its characteristics?

The characteristics of the smooth muscle The smooth muscle has a shape of a spindle with tapering at both ends. It is usually found around the blood circulatory pathway and the digestive system. They work using reflex rather than controlled through the brain and nervous system, often time called as an autonomous muscle system.

What is smooth muscle activity responsible for?

Smooth muscle lines many parts of the circulatory system, digestive system, and is even responsible for raising the hairs on your arm. In the circulatory system, smooth muscle plays a vital role in maintaining and controlling the blood pressure and flow of oxygen throughout the body.

What does the smooth muscle do?

Smooth muscle determines the flow of blood in the arteries. Smooth muscles move food through the digestive tract. In one’s eye the pupillary sphincter muscles is responsible for shrinking the size of the pupil.

What are smooth, skeletal, and striated muscles?

Is smooth muscle is capable of Autorhythmic contractions?

Contractions of the heart (heartbeats) are controlled by specialized cardiac muscle cells called pacemaker cells that directly control heart rate. This property is known as autorhythmicity. Neither smooth nor skeletal muscle can do this.
