The muscle type with striations, voluntary control, and a bony attachment is what?

• A. Skeletal muscle
• B. Smooth muscle
• C. Cardiac muscle
• D. Connective tissue

Answer: (A)

Striated appearance, voluntary control, and attachment to bones describe skeletal muscle. The stripes come from the organized sarcomeres inside the muscle fibers, giving the characteristic banding pattern. Voluntary control means these muscles are governed by the somatic nervous system, so we consciously decide to move them. They attach to bones (usually via tendons), and by contracting they pull on the skeleton to produce movement. Smooth muscle is non-striated and controlled involuntarily, found in walls of organs. Cardiac muscle is striated as well but is involuntary and makes up the heart, not attachments to bones.
