During flexion, the distance between the spinous processes is increased.
Distance travelled is the total distance covered during the motion and displacement is the distance between the final and initial position.
a concentric contraction- a concentric contraction involves the muscle length, shortening during a contraction! YA-trick-YA!
Yes, the Z line shortens during muscle contraction.
During the phase change from a liquid to a gas, the average distance between molecules always increases.
During muscle contraction the actin heads pull the sarcomere closed
distance
Troponin is another protein involved in skeletal muscle contraction. It works in conjunction with tropomyosin to regulate the interaction between actin and myosin filaments during muscle contraction.
Isotonic contraction
152,098,232 kilometers.
The A band is the dark band in a sarcomere that contains thick myosin filaments and does not change length during muscle contraction. The I band is the light band that contains thin actin filaments and shortens during muscle contraction. The A band provides stability and structure, while the I band allows for muscle contraction and relaxation.
