Cardiac Skeletal Muscle. Skeletal muscles are attached to bones all over the body which does not self-stimulate has a high speed of contraction and energy requirement and is responsible for performing voluntary muscular movements. Skeletal and cardiac muscles are known as striated muscles because the filaments of actin and myosin that power their contraction are organized into repeating arrays called sarcomeres that have a striated microscopic appearance.
Cardiac muscles function solely for pumping blood away from the heart towards the lungs and throughout the body. While the cardiac muscles are semi-spindle the skeletal muscles are cylindrical in shape. Cardiac muscle fibers also possess many mitochondria and myoglobin as.
The skeletal muscles are tightly bound together when compared to cardiac muscles.
In that it possesses the contractile units called sarcomeres. The muscular systems in vertebrates are controlled through the nervous system although some muscles such as the cardiac muscle can be completely autonomous. In that it possesses the contractile units called sarcomeres. It permits movement of the body maintains posture and circulates blood throughout the body.
