The nervous system functions include integration of stimuli, initiation of movement, and reflex arcs for quick responses.
Integration: Stimuli from sensory structures are processed in the nervous system by comparing them with other stimuli, memories, or the person's state.
Initiation of Movement: Descending motor commands from the cortex to skeletal muscles lead to movement initiation.
Reflex Arcs: Different reflex arcs function in initiating quick responses without conscious thought.
