Which type of muscles do the uterus, iris of the eye, and bronchi contain?

Key Points

• The uterus, iris of the eye, and bronchi contain smooth muscles.
• Smooth muscles are involuntary, non-striated muscles found in various internal organs.
• These muscles are responsible for various involuntary movements in the body such as the contraction of the uterus during childbirth, adjustment of the iris in response to light, and regulation of airflow in the bronchi.
• Unlike skeletal muscles, smooth muscles are not under conscious control and are regulated by the autonomic nervous system.

Additional Information

• Striated muscles include skeletal muscles that are under voluntary control and are characterized by their striped appearance.
• Skeletal muscles are attached to bones and help in body movements.
• Cardiac muscles are specialized striated muscles found only in the heart, responsible for pumping blood throughout the body.
• Smooth muscles are also found in the walls of blood vessels, digestive tract, and other hollow organs.
