1. Smooth muscle

   Smooth muscle is an involuntary non-striated muscle, so-called because it has no sarcomeres and therefore no striations (bands or stripes). It is divided into two subgroups, single-unit and multiunit smooth muscle. Within single-unit muscle, the whole bundle or sheet of smooth muscle cells contracts as a syncytium. Smooth muscle is found in the walls of hollow organs, including the stomach, intestines, bladder and uterus; in the walls of passageways, such as blood, and lymph vessels, and in the tracts of the respiratory, urinary, and reproductive systems. In the eyes, the ciliary muscles, a type of smooth muscle, dilate and contract the iris and alter the shape of the lens. In the skin, smooth muscle cells such as those of the arrector pili cause hair to stand erect in response to cold temperature or fear.

1. smooth muscle

   Smooth muscle refers to a type of involuntary non-striated muscle that makes up the walls of organs and structures like the esophagus, stomach, intestines, bronchi, uterus, urethra, and blood vessels. Unlike the skeletal muscles, smooth muscles are not under conscious control. Instead, they are directly controlled by autonomic nerves. They help in various processes like peristalsis, blood flow control, and maintaining organ size.
