Question

multiple choice question

which describes smooth muscle tissue?

uninucleate, non-striated
uninucleate, striated
multinucleate, non-striated
multinucleate, striated

Explanation:

Analyze smooth muscle nuclei

Using the Smooth Muscle Characteristics knowledge point
Smooth muscle cells are fusiform (spindle-shaped) cells that contain a single, centrally located nucleus. Therefore, they are classified as uninucleate.

Analyze smooth muscle striations

Using the Smooth Muscle Characteristics knowledge point
Unlike skeletal and cardiac muscle, smooth muscle lacks the highly organized sarcomere arrangements that produce visible light and dark bands under a microscope. Consequently, it is non-striated.

Match with options

Using the Smooth Muscle Characteristics knowledge point
Combining these two structural features, smooth muscle tissue is described as uninucleate and non-striated. This matches the first option.

Answer:

• (A) Uninucleate, non-striated (Correct answer)
• (B) Uninucleate, striated
• (C) Multinucleate, non-striated
• (D) Multinucleate, striated
