For instance, you can join your hands together, pushing down with one hand and pushing up with the other. In each arm, the muscles that provide the force are connected to the bones of the arm by tendons. If you increase the forces but keep the angles the same, the muscles will still contract. Explain how this is possible.arrow_forwardWhat is the joint action at the finger (MCP) joints as shown below? must watch clip to answer https://www.youtube.com/watch?v=PKlCxd0xRZI a. Abduction b.
