Which of the following is NOT a characteristic of skeletal muscle?

Question

BlackTom AI · Accepted Answer

Question restatement: Which of the following is NOT a characteristic of skeletal muscle?

Option 1: 'attached to bones' — This is a true characteristic, as skeletal muscles attach to bones via tendons and produce movement of the skeleton. It aligns with the general function and anatomy of skeletal muscle.

Option 2: 'striations and multinucleated' — Skeletal muscle fibers exhibit striations under the microscope and are multinucleated (many nuclei per fiber), due to their syncytial organization. This combines two well-known features of skeletal muscle.

Option 3: 'branched fibres and binucleate' — This statement is problematic for skeletal muscle. Skeletal muscle fibers are typically long, cylindrical, and not branched; they are multinucleated (many nuclei), not binucleate. The presence of branching and binucleation would more closely resemble other muscle types or atypical conditions, making this description inconsistent with standard skeletal muscle.

Option 4: 'voluntary control' — Skeletal muscle is under voluntary control via somatic motor neurons, which is a defining functional characteristic alongside its anatomical features. This aligns with how skeletal muscle operates in voluntary movement tasks.

In summary, evaluating each option shows that only the third statement contains features that do not match the canonical properties of skeletal muscle: branching and binucleation are not typical characteristics of skeletal muscle fibers, whereas attachment to bones, striations with multinucleation, and voluntary control are consistent with skeletal muscle biology.
