  1. 2. nervous system- the portion of the nervous system lying outside the brain and spinal cord.
  2. 7. nervous system- The sympathetic nervous system is involved in preparing the body for stress-related activities, and it slows bodily processes that are less important in emergencies such as digestion.
  3. 10. nervous system- the part of the nervous system comprising the brain and spinal cord.
  4. 11. callosum-The corpus callosum, also known as the great commissure, is a bundle of nerve fibers that connects the left and right hemispheres of the brain.
  5. 13. The forebrain controls body temperature, reproductive functions, eating, sleeping, and the display of emotions.
  6. 15. Neurotransmitters are chemical messengers in the body. Their job is to transmit signals from nerve cells to target cells.
  7. 18. neurons- These are sensory neurons carrying nerve impulses from sensory stimuli toward the central nervous system and brain. Afferent neurons carry signals to the brain and spinal cord as sensory data.
  8. 20. cortex-a sheet of neural tissue that is outermost to the cerebrum of the mammalian brain.

  1. 1. one of the three major regions of our brains, located at the lower back part of the brain.
  2. 3. neurons- These are motor neurons carrying neural impulses away from the central nervous system and toward muscles to cause movement. Efferent neurons send signals from the brain to the muscles, glands, and organs of the body in response to sensory input.
  3. 4. nervous system- one of two branches of the autonomic nervous system (ANS), the other being the sympathetic nervous system. It is defined functionally as the system controlling rest, repair, enjoyment, eating, sleeping, sexual activity, and social dominance, among other functions.
  4. 5. lobe-The function of the temporal lobe centers around auditory stimuli, memory, and emotion. The temporal lobe contains the primary auditory complex. This is the first area responsible for interpreting information in the form of sounds from the ears.
  5. 6. lobe-The occipital lobe is the visual processing area of the brain. It is associated with visuospatial processing, distance and depth perception, color determination, object and face recognition, and memory formation.
  6. 8. lobe-The brain's parietal lobe is located immediately behind the frontal lobe, and is involved in processing information from the body's senses. It contains the somatosensory cortex, which is essential for processing sensory information from across the body, such as touch, temperature, and pain.
  7. 9. the quality of being easily shaped or molded.
  8. 12. nervous system- the part of the nervous system responsible for control of the bodily functions not consciously directed, such as breathing, the heartbeat, and digestive processes.
  9. 14. The basic unit of nerve tissue; the nerve cells. Neurons carry and transmit electrical signals throughout the nervous system.
  10. 16. nervous system- the part of the nervous system comprising the sensory and motor neurons that innervate the sense organs and the skeletal muscles, as opposed to the autonomic nervous system.
  11. 17. A synapse is the small gap between two neurons, where nerve impulses are relayed by a neurotransmitter from the axon of a presynaptic (sending) neuron to the dendrite of a postsynaptic (receiving) neuron.
  12. 19. lobe-The frontal lobe is the most anterior (front) part of the brain. It extends from the area behind the forehead back to the precentral gyrus. As a whole, the frontal lobe is responsible for higher cognitive functions such as memory, emotions, impulse control, problem solving, social interaction, and motor function.
