1. Central Nervous System- receives information from your body to help you react to the stimuli.
  2. Cerebral Hemisphere- the cerebral hemisphere controls conscious thought, memory, controls voluntary movements, learning, reasoning, and behavior.
  3. Brainstem- the brainstem connects the spinal cord with the cerebrum and it processes all sensory and motor functions.
  4. Epithalamus- some functions of its components include the secretion of melatonin, it controls circadian rhythms, regulation of motor patterns, and emotion.
  5. Thalamus- the thalamus receives signals modulates the flow of information and sends them to the cortex.
  6. Hypothalamus-it receives the taste and smell information
  7. Midbrain- the midbrain is part of the central nervous system and controls vision, hearing and the control of motor movements, consciousness, and temperature.
  8. Pons- in the brain the pons relays sensory information between the cerebellum and the cerebrum it relays information and controls arousal. It relays information from the two parts of your brain.
  9. Midulla-the medulla oblongata is the part of the brain that controls breathing, heart rate and blood pressure in your body.
  10. Cerebellum-the cerebellum modulates rather than and initiates movement it controls motor skills like balance and coordination.
    11.  
  11. Spinal Cord-the spinal cord carries impulses between your body and your brain.
  12. Peripheral Nervous System-the peripheral nervous system carries information from the organs muscles and glands to your brain.
  13. Cranial Nerves- cranial nerves are nerves directly connected to the brain they controlled the eyes mouth and ears in the muscles on your face.
  14. Spinal Nerves- spinal nerves transmit signals between the brain and the rest of the body which are interpreted as pain, touch, pressure, sensation, or temperature.
  15. Receptor-receptors sense what is going on in your body and relays the information back to your brain.
  16. Sensory Neuron- sensory neurons converts various external stimuli that come from the environment into corresponding internal stimuli and convey sensory information to the brain.
  17. Posterior Root- the posterior root is a nerve fiber bundle of spinal nerves that carry sensory information to the central nervous system.
  18. Ganglion-is regarded as the gray matter of the spinal cord.
  19. Motor Neuron-the motor neuron is a nerve cell that specifically controls the voluntary muscles of your body.
  20. Anterior Root- the anterior root is also called the ventral root it carries neural signals away from the central nervous system towards the limbs and the organs.
  21. Effector- the effector is the gland or the muscle that causes the response stimulated by the nervous system.
