| 11234865793 | Nervous System | The body's speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems. | 0 | |
| 11234865794 | Central Nervous System | The brain and spinal cord. | 1 | |
| 11234865795 | Peripheral Nervous System | The sensory and motor neurons that connect the central to the rest of the body. | 2 | |
| 11234865796 | Nerves | Bundled axons that form neural "cables" connecting the central nervous system with muscles, glands, and organs. | 3 | |
| 11234865797 | Sensory Afferent Neurons | Neurons that carry INCOMING information from the sensory receptors to the brain and spinal cord. | 4 | |
| 11234865798 | Motor Efferent Neurons | Neurons that carry OUTGOING information from the brain and spinal cord to the muscles and glands. | 5 | |
| 11234865799 | Interneurons | Neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs. | 6 | |
| 11234865800 | Somatic Nervous System | The division of the peripheral nervous system that controls voluntary movements of skeletal muscles. Also called the skeletal nervous system. | 7 | |
| 11234865801 | Autonomic Nervous System | The part of the peripheral nervous system that controls the self regulated action of internal organs and glands | 8 | |
| 11234865802 | Sympathetic | (autonomic) arousing | 9 | |
| 11234865803 | Parasympathetic Nervous System | (Division of the autonomic nervous) calming | 10 | |
| 11234865804 | Reflex | Simple, automatic response to sensory stimulus such as the knee-jerk response. | 11 | |
| 11234865805 | Endocrine System | Body's slow chemical communication system; a set of glands that secrete hormones into the bloodstream. | 12 | |
| 11234865806 | Hormones | Chemical messengers that are manufactured by the endocrine glands. They travel through the bloodstream and affect other tissues. | 13 | |
| 11234865807 | Adrenal Glands | Pair of endocrine glands that sit above the kidneys that secrete hormones epinephrine and nor-epinephrine. | 14 | |
| 11234865808 | Pituitary Gland | Endocrine gland (most influential). Under the influence of the hypothalamus, it regulates growth and controls other endocrine glands. | 15 |
