the prime mover is the muscle responsible for most of the movement in a group of muscles; called the chief muscle.
skeletal
The muscle cell is most likely part of the muscular system. It is responsible for movement, posture, and production of heat.
Skeletal muscle is most often controlled by conscious thought.
The site that undergoes most of the movement when a muscle contracts.
Muscle cells would have the most mitochondria because they require a lot of energy to support muscle contraction and movement. Mitochondria are the powerhouse of the cell, responsible for producing ATP, the energy currency of the cell.
The musculoskeletal system, comprising muscles and bones, provides the power and structure for wing movement in birds. And the nervous system coordinates muscle contractions and movement patterns to control the flapping of wings in flight.
Mitochondrion because they are responsible for producing energy
The primary muscle attached at the point of insertion is the muscle that undergoes the most movement when the muscle contracts. For example, in the bicep curl exercise, the bicep muscle is the primary muscle attached at its point of insertion on the radius bone in the forearm.
Skeletal muscle fibers are unusual because they are multinucleated, meaning they have multiple nuclei within a single cell. Additionally, they are long and cylindrical in shape, allowing them to generate strong contractions to facilitate movement. Lastly, skeletal muscle fibers contain a specialized structure called sarcomeres, which are responsible for the muscle's contractile properties.
Skeletal muscle is the most common type of muscle in the body. It is attached to bones and is responsible for voluntary movements like walking and lifting objects.
