For example, in the context of anatomy, if a structure is located more towards the front of the body, it is said to be 'ahead' of another structure that is located more towards the back.
In neurology, 'ahead' can also refer to the direction of nerve impulses traveling from the brain to the rest of the body. For instance, the impulses from the brain to the hand travel 'ahead' to the hand.
