  1. 3. transmitted by the motor (efferent) nerves from the central nervous system to the periphery (muscles and glands).
  2. 7. a specialized cell transmitting nerve impulses; a nerve cell
  3. 8. mobilizes energy and resources during times of stress and arousal
  4. 9. are the dura mater, the arachnoid mater, and the pia mater
  5. 13. conserves energy and resources during relaxed states
  6. 14. long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body
  7. 17. 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)
  8. 18. is the largest part of the human brain, associated with higher brain function such as thought and action
  9. 19. the anterior part of the brain, including the cerebral hemispheres, the thalamus, and the hypothalamus
  10. 20. 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

  1. 1. 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
  2. 2. made of neurons connecting the CNS with internal organs
  3. 4. is a portion of the brain that contains a number of small nuclei with a variety of functions
  4. 5. an organ of soft nervous tissue contained in the skull of vertebrates
  5. 6. n 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
  6. 10. a group of nerve cell bodies located in the autonomic nervous system
  7. 11. 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. 12. the hindbrain is made up of
  9. 15. 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. 16. the chief controlling and coordinating system of the body
