Question

Quizplus · Accepted Answer

The cells in the Petri dish are striated and multinucleate, characteristics of skeletal muscle. Cardiac muscle is also striated and multinucleate but has a distinct branching pattern and is only found in the heart. Smooth muscle is not striated and is found in walls of organs such as the digestive tract and blood vessels. Involuntary muscle is a general term that includes both smooth and cardiac muscle. Therefore, the best choice is D, skeletal muscle.
