The insect foregut receives food and may include structures such as crop and gizzard. It is lined with cuticle and helps store or mechanically process food.

At the neuromuscular junction, motor neurons communicate with muscle fibers. This allows nervous control of walking, flying, feeding, and other movements.

Insect muscles work in coordinated opposing groups. One muscle contracts to move a body part while another can return it, allowing controlled locomotion.
