b produce and manage movement

Explanation:

nerve cells are there to move muscles, send signals to glands, or register sensory stimuli.

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.
