Given below are two statements.

Statement I : Smooth muscles are unstriped, involuntary and form bundles called fascicles.

Statement II : Smooth muscles are found in the alimentary canal, reproductive tract, etc.

In light of the above statements, choose the correct answer from the options given below.

Statement I is incorrect but statement II is correct.

Smooth muscles are indeed unstriped (they lack the striations seen in skeletal muscle due to the arrangement of actin and myosin filaments), and they are involuntary (controlled by the autonomic nervous system and hormones, not under conscious control). However, smooth muscles do not typically form bundles called fascicles like skeletal muscles do. Instead, smooth muscle cells are arranged in sheets or layers.

Smooth muscles are found in various organs throughout the body, including the walls of the alimentary canal (such as the stomach and intestines), the reproductive tract (such as the uterus), blood vessels, respiratory tract, and other locations where involuntary movement is necessary.
