  1. 2. neurons - the nerve fibers responsible for bringing sensory information from the outside world into the brain.
  2. 3. lobe - sensory perception and integration, including the management of taste, hearing, sight, touch, and smell. It is home to the brain's primary somatic sensory cortex (see image 2), a region where the brain interprets input from other areas of the body.
  3. 4. nervous system - made up of the brain and spinal cord.
  4. 9. - a chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.
  5. 11. callosum - a large bundle of more than 200 million myelinated nerve fibers that connect the two brain hemispheres, permitting communication between the right and left sides of the brain.
  6. 13. - the ability of the nervous system to change its activity in response to intrinsic or extrinsic stimuli by reorganizing its structure, functions, or connections.
  7. 16. - information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system.
  8. 17. nervous system - divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands. Somatic nervous system (SNS): Controls muscle movement and relays information from ears, eyes and skin to the central nervous system.
  9. 18. nervous system - a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.
  10. 19. lobe - the largest lobes in the human brain and they are also the most common region of injury in traumatic brain injury.
Down
  1. 1. cortex - the outer layer that lies on top of your cerebrum.
  2. 3. nervous system - a network of nerves that relaxes your body after periods of stress or danger.
  3. 5. neurons - motor neurons, are the nerve fibers responsible for carrying signals from the brain to the peripheral nervous system in order to initiate an action.
  4. 6. nervous system - Your somatic nervous system is a subdivision of your peripheral nervous system that stretches throughout nearly every part of your body. The nerves in this system deliver information from your senses to your brain. They also carry commands from your brain to your muscles so you can move around.
  5. 7. lobe - the rearmost lobe in each cerebral hemisphere of the brain.
  6. 8. - region of the developing vertebrate brain; it includes the telencephalon, which contains the cerebral hemispheres, and, under these, the diencephalon, which contains the thalamus, hypothalamus, epithalamus, and subthalamus.
  7. 10. nervous system - best known for its role in responding to dangerous or stressful situations.
  8. 12. - region of the developing vertebrate brain that is composed of the medulla oblongata, the pons, and the cerebellum. The hindbrain coordinates functions that are fundamental to survival, including respiratory rhythm, motor activity, sleep, and wakefulness.
  9. 14. - small pocket of space between two cells, where they can pass messages to communicate.
  10. 15. lobe - They are most commonly associated with processing auditory information and with the encoding of memory. The temporal lobes are also believed to play an important role in processing affect/emotions, language, and certain aspects of visual perception.
