Five fundamentals of arms and feet?

1. Joints: Arms and feet are composed of multiple bones connected by joints, which allow for movement and flexibility.

2. Muscles: Muscles are attached to the bones and provide the force necessary for movement.

3. Bones: The bones of the arms and feet provide support, protection, and allow for movement.

4. Tendon: Tendons connect muscles to bones, transmitting the force generated by muscles to the bones, resulting in movement.

5. Nerves: Nerves provide sensory information to the brain about the position and movement of the limbs, allowing for coordination and control.
