Skeletal muscle
Myoglobin is synthesized in muscle cells and imparts the reddish-brown color of skeletal muscle tissue. Like hemoglobin, myoglobin can combine loosely with oxygen. This ability to temporarily store oxygen reduces a muscle's requirement for a continuous blood supply during muscular contraction.
A skeletal muscle.
The characteristic striated appearance of skeletal muscle is due to the arrangement of alternating protein filaments composed of actin and myosin. These filaments slide past each other during muscle contraction, causing the muscle to shorten and generate force.
