Question

conclusion

1. below are the five structures involved in creating movement. number them (1 - 5) in the correct order of how movement occurs — starting with where the signal begins and ending with what actually moves.

___ brain
___ bones
___ joints
___ muscles
___ tendons
then explain:
in 2 - 3 sentences, describe how movement happens when the chicken wing (or your arm) moves, using all five structures in your answer.

Explanation:

Step1: Signal origin

The brain initiates the movement signal.

Step2: Signal transmission

The signal is sent to the muscles.

Step3: Muscle - tendon interaction

Muscles contract and pull on tendons.

Step4: Tendon - bone interaction

Tendons are attached to bones.

Step5: Bone - joint movement

Bones move at joints.

Answer:

Brain: 1; Muscles: 2; Tendons: 3; Bones: 4; Joints: 5

Movement occurs as the brain sends a signal to the muscles. The muscles contract, pulling on tendons which are attached to bones. The bones then move at the joints.
