The precision of movement produced by a muscle is due
No, muscle contraction doesn't always promote movement. For example, in an isometric contraction, the muscle does not change length, so movement is not produced. Additionally, some muscles can contract to stabilize joints without producing visible movement.
Skeletal muscles are attached to the bones by tough cords called tendons. When nerve signals are sent from the brain and spinal cord, these muscles contract to produce movement.
A movement that targets one muscle or one section of a muscle.
Isotonic contractions are the type that involve muscle movement. This movement is due to a change in length as the muscle fibers shorten or lengthen.

The three functional roles in a movement that are used to characterize muscle groups are Origin, Insertion, & Contraction (Actions). However my instructor argued that the key word was functional therefore the answer she felt was correct is/was agonists, antagonists, or synergists.
Yes, a synergist is a helper muscle that assists the prime mover (agonist) during skeletal muscle movement. Synergists can stabilize joints and facilitate more efficient movement by working alongside the primary muscle responsible for a specific action. They play a crucial role in coordinating muscle contractions and ensuring smooth movement.
The arrangement of skeletal muscle bands in muscle contraction is significant because it allows for efficient and coordinated movement. The bands, made up of actin and myosin filaments, slide past each other during contraction, causing the muscle to shorten and generate force. This arrangement enables muscles to contract quickly and with precision, allowing for smooth and controlled movements.
Smooth muscle is responsible for involuntary movement, just like skeletal muscle, only the movement is usually in the internal organs.
