ATP (Adenosine triphosphate) is the primary energy source that muscles use for contraction during motion.

The cerebellum is primarily responsible for coordinating voluntary movements and maintaining balance.

The vestibular system is responsible for maintaining balance and spatial orientation by detecting changes in head position.

Proprioceptors are sensory receptors that provide information about body position and movement, crucial for coordination.

Flexibility refers to the range of motion around a joint, which is essential for overall movement efficiency.

Skeletal muscle is the type of muscle that is under voluntary control and is responsible for movement.

The motor cortex is responsible for planning, controlling, and executing voluntary movements.

The nervous system, particularly the vestibular system, plays a crucial role in maintaining balance during motion.

Translational motion refers to movement in a straight line, as opposed to rotational or circular motion.
