Muscle contraction will always promote movement of body parts regardless of how they are attached. true or false

False.

Explanation:

Muscles are one of the most important tissue of our body that helps in the movement and contraction of the body. Three main types of skeletal muscles are cardiac muscle, smooth muscle and skeletal muscle.

The muscles are attached to bones by tendons.  The attachment of muscles will determine its movement. The contraction of muscles result in the movement of body parts but not always. The joining of muscles with immovable bones do not result in the movement.

Thus, the answer is false.
