Definitions:

Neurotransmitters

Chemical messengers in the body that transmit signals between neurons or from neurons to muscles, playing key roles in various physiological processes and behaviors.

Myoneural Junction

The site at which a nerve cell communicates with a muscle cell, enabling muscle contraction and movement.

Muscle Movement

The physiological process by which muscles contract and relax, enabling the body to move.

Tibia and Fibula

The two long bones in the lower leg, where the tibia, or shinbone, supports most of the body's weight and the fibula, or calf bone, supports muscles and stabilizes the ankle.
