Karl catches a football and runs down the field toward the end zone, attempting to score a touchdown. Neurologically, are taking prompts from Karl's brain and transmitting this information to his legs, commanding them to run.

Neurologically, motor neurons are taking prompts from Karl's brain and transmitting this information to his legs, commanding them to run

Explanation:

Motor neurons are recognized as one of the most important types of nerve cells because they have highly-specialized functions in the brain and the spinal cord.  These cells are fundamental for the movement of voluntary muscles and therefore play essential roles in walking, eating, speaking, breathing, etc.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
