Question:
Smooth muscles are
Options:
  • 1. involuntary, fusiform, non-striated
  • 2. voluntary, multinucleate, cylindrical
  • 3. involuntary, cylindrical, striated
  • 4. voluntary, spindle-shaped, uninucleate
Solution:
(1) Smooth muscles are involuntary, fusiform and non-striated. These muscles are located in the inner walls of hollow visceral organs of the body like alimentary canal, reproductive tract etc. They do not exhibit any striation and are smooth in appearance. Their activities are under autonomic and hormonal control and thus they are also known as involuntary muscles. Hence Option (1) is correct. Short Trick The key words for correct answers are non-striated and involuntary and these are present in option (1) only.
