Across
  1. 7. The _____ gland is a tiny organ that serves as the primary gland for the body, producing several hormones and activating other glands to produce hormones.
  2. 11. The part of the parietal lobe where all received sensory input signals, such as touch and taste, are sent through neurons to the ____ ____ to be processed.
  3. 12. The _____lobes are responsible for processing smell and sound, as well as the ability to recognize and understand words and language.
  4. 13. _____ disorders are related to the brain, spinal cord, and nerves.
  5. 15. A nerve cell that sends signals or transmits nerve impulses.
  6. 17. A region of the brain below the thalamus that coordinates both the autonomic nervous system and the activity of the pituitary, controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity.
  7. 21. The part of the nervous system that includes the brain and spinal cord.
  8. 23. Bundles of neurons.
  9. 24. The part of the nervous system that includes nerves and is not part of the brain and spinal cord.
  10. 25. A fatty substance that surrounds the axon and increases the speed at which signals travel (______ sheath)
  11. 27. Chemical that assists in passing a signal through the synapse.
  12. 28. The part of the frontal lobe where nerve impulses initiate voluntary muscular activity.
  13. 29. The part of the occipital lobe that receives and processes sensory nerve input from the eyes.
  14. 30. Either of two masses of gray matter lying between the cerebral hemispheres, relaying sensory information and acting as a center for pain perception.
Down
  1. 1. A branch extending from a neuron that receives signals from another neuron through a synapse.
  2. 2. The _____ lobes play a large role in your behavior and personality, such as planning, voluntary muscle movements, mood, emotions, social interactions, and attention, and are also involved in memory retrieval and storage.
  3. 3. A broad band of nerves that connects the left and right hemispheres of the cerebrum.
  4. 4. The center trunk of the brain that continues downward to form the spinal cord. Responsible for vital functions like heartbeat.
  5. 5. The part of the brain at the back of the skull in vertebrates. Its function is to coordinate and regulate muscular activity (small brain)
  6. 6. The gap between the branches extending from a neuron's axon that sends a signal to the next neuron.
  7. 8. Type of neurons that pass signals from the brain or spinal cord to a muscle or gland to help you move.
  8. 9. The _____lobes are primarily responsible for visual perception and are involved in some forms of visual, short-term memory.
  9. 10. The long extension from a nerve cell along which signals travel.
  10. 14. The four main parts of each cerebral hemisphere of the brain
  11. 16. The X-shaped structure formed at the point below the brain where the two optic nerves cross over each other.
  12. 18. A pair of nerves transmitting input signals to the brain from the retina at the back of the eye.
  13. 19. The part of the temporal lobe that processes auditory input signals (sound).
  14. 20. Type of neurons responsible for receiving external stimuli from the body's environment and passing that signal through nerves to the central nervous system.
  15. 22. The _____lobes are responsible for sensing touch, spatial processing (being able to tell where objects are in space), language, and memory.
  16. 26. Large grey matter of the brain. Located in the front area of the skull and consists of two hemispheres, left and right. It is responsible for the integration of complex sensory and neural functions and the initiation and coordination of voluntary activity in the body.
