  1. 3. is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and myelinated as well as unmyelinated axons), glial cells (astroglia and oligodendrocytes), synapses, and capillaries
  2. 5. transmitted by the motor (efferent) nerves from the central nervous system to the periphery (muscles and glands).
  3. 6. made of neurons connecting the CNS with internal organs
  4. 9. that it contains numerous cell bodies and relatively few myelinated axons, while white matter contains relatively very few cell bodies and is composed chiefly of long-range myelinated axon tracts
  5. 10. the chief controlling and coordinating system of the body
  6. 12. conserves energy and resources during relaxed states
  7. 13. are the dura mater, the arachnoid mater, and the pia mater
  8. 14. long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body
  9. 16. the stemlike portion of the brain connecting the cerebral hemispheres with the spinal cord, and comprising the pons, medulla oblongata, and midbrain; considered by some to include the diencephalon
  10. 18. is the largest part of the human brain, associated with higher brain function such as thought and action
  11. 19. an organ of soft nervous tissue contained in the skull of vertebrates
Down
  1. 1. a group of nerve cell bodies located in the autonomic nervous system
  2. 2. is a portion of the brain that contains a number of small nuclei with a variety of functions
  3. 4. the anterior part of the brain, including the cerebral hemispheres, the thalamus, and the hypothalamus
  4. 7. the hindbrain is made up of
  5. 8. impulses are transmitted by the sensory (afferent) nerves from the periphery (skin, mucous membranes, muscles, tendons, joints, and special sense organs) to the central nervous system (CNS)
  6. 11. mobilizes energy and resources during times of stress and arousal
  7. 15. a whitish fiber or bundle of fibers that transmits impulses of sensation to the brain or spinal cord, and impulses from these to the muscles and organs
  8. 17. is the part of the peripheral nervous system associated with skeletal muscle voluntary control of body movements. The SoNS consists of afferent nerves and efferent nerves
