Skeletal muscles have unique structures such as striations, which are alternating light and dark bands visible under a microscope due to the organized arrangement of actin and myosin filaments. They are multinucleated, meaning each muscle fiber contains multiple nuclei located at the periphery of the cell. Additionally, skeletal muscles are surrounded by connective tissue layers, including the epimysium, perimysium, and endomysium, which provide support and compartmentalization for muscle fibers. These features enable skeletal muscles to contract forcefully and efficiently for voluntary movements.

What structures are skeletal muscles attached?
The muscles attach on the inside of these coverings at flexible joints.
What structures work in antagonistic to move bones?
Skeletal Muscles
What muscles are the muscles that move bones?

What are rodlike structures within skeletal muscles that contain filaments organized into sarcomeres?
myofilaments
Is the quadriceps muscles in the leg and example of a smooth muscle?
No, the quadriceps muscles in the leg are not an example of smooth muscle; they are skeletal muscles. Skeletal muscles are under voluntary control and are responsible for movement and stability. In contrast, smooth muscles are involuntary and found in structures such as blood vessels and the digestive tract.
What are skeletal muscles like?
Skeletal muscles are spindle, flat-shaped or circular in shape. The circular ones have attachments called "heads" at their ends. Most of the skeletal muscles are attached to bones by cord-like tendons. Some of these muscles are attached to skin, cartilage, or other structures in the body such as the eye ball. Some of these muscles have intermediate tendons as well as aponeurosis.
