Sensory organs detect external stimuli (light, sound, balance) and transmit neural signals via cranial nerves to the brain.

Motor pathways in the brain, spinal cord, and peripheral nerves direct skeletal muscle contraction and coordination.

The hypothalamus links the nervous system to the endocrine system by regulating hormone release from the pituitary gland.
