Question

State whether the following statements are true or false

Single-unit smooth muscle fibres may contract automatically and rhythmically.

• A. True
• B. False

Answer 1

The correct option is A True

Single-unit smooth muscle in the walls of the viscera, called visceral muscle, has a stress-relaxation response that permits muscle to stretch, contract, and relax as the organ expands. Multiunit smooth muscle cells do not possess gap junctions and contraction does not spread from one cell to the next

So, the correct answer is 'True'
