| These pair of body systems regulate and coordinate body functions | Nervous & Endocrine Systems |
| The 2 main divisions of the nervous system | Central Nervous System (CNS) and Peripheral Nervous System (PNS) |
| The 2 divisions of the Peripheral Nervous System | Sensory division and Motor division |
| Smallest structure of the nervous system | neuron |
| Nerve impulses travel across a synapse with the help of | neurotransmitters |
| Light passes through the eye in this order | Cornea, pupil, lens, retina, optic nerve |
| Major part of central nervous system | brain & spinal cord |
| The type of neuron that carries messages from the sense organs to the brain | sensory neuron |
| The type of neuron that carries messages from the brain to the muscles | motor neuron |
| Type of neuron that connects sensory and motor neurons | interneurons |
| Part of the brain that controls decisions, mood, creating | frontal lobe |
| Part of the brain that controls hearing and memory | temporal lobe |
| Part of the brain that coordinates physical skills and balance | cerebellum |
| Part of the brain where breathing and heart rate are controlled | Brain Stem |
| Part of the brain where messages from the eyes are interpreted | occipital lobe |
| Part of the brain where touch and pain are recognized | parietal lobe |
| Area of the eye that carries signal to the brain | optic nerve |
| Part of the eye that has color | iris |
| The opening of the eye | pupil |
| The outer covering of the eye | cornea |
| The tissue in the back of the eye that converts light to electrical signals | retina |
| The part of the eye that focuses images | lens |
| Specialized cells of the retina that sense color | cones |
| Specialized cells of the retina that sense dark and light | rods |
| Covering of the axon in a neuron | Myelin Sheath |
| Part of neuron that receives messages | Dendrites |
| Part of neuron that sends messages | axon terminal |
| Part of neuron that contains nucleus and organelles | cell body |
