Scelta multipla

D

Guida verificata passo dopo passo1
Step 1: Begin by understanding the three types of muscle tissue: skeletal, cardiac, and smooth. Each type has distinct characteristics in terms of structure, function, and control.
Step 2: Review the structural features of smooth muscle cells. Smooth muscle cells are spindle-shaped and typically have a single nucleus, not multinucleated. This is a key point to identify the false statement.
Step 3: Examine cardiac muscle tissue. Cardiac muscle is found exclusively in the heart and is responsible for pumping blood throughout the body. It is involuntary and has unique features like intercalated discs.
Step 4: Consider skeletal muscle tissue. Skeletal muscle is under voluntary control, meaning its contraction is consciously controlled by the nervous system. It is multinucleated and striated.
Step 5: Compare the statements provided in the problem to the characteristics of each muscle type. Identify the false statement by recognizing that smooth muscle cells are not multinucleated, which contradicts the claim in the problem.
