In an exoskeleton, muscles are attached externally to the skeleton, causing them to pull on the outside of the joint, which requires bilateral muscles to contract and relax in an alternating pattern to achieve movement. In an endoskeleton, muscles are attached internally to the skeleton, allowing for a more direct relationship between muscle contraction and joint movement, typically involving antagonistic muscle pairs to bend and extend the joint more efficiently.
