  1. Anterior root
    An extension from the anterior horn of the spinal cord containing the axons of lower motor neurons; some also contain the axons of visceral motor neurons.
  2. arachnoid mater
    The middle meninx that surrounds the brain and spinal cord.
  3. basal nuclei
    Nuclei within the cerebral hemispheres that function in the initiation of movement and the prevention of inappropriate movements.
  4. cauda equina
    A large bundle of nerve roots given off at the terminal end of the spinal cord.
  5. central canal
    A small, cerebrospinal fluid–filled canal located in the center of the spinal cord.
  6. central sulcus
    A sulcus of each cerebral hemisphere that separates the frontal lobes from the parietal lobes.
  7. cerebellum
    The posteroinferior portion of the brain; responsible for regulating ongoing movement and the correction of motor error.
  8. cerebral aqueduct
    A hollow, cerebrospinal fluid–filled channel that connects the third ventricle in the diencephalon with the fourth ventricle in the brainstem.
  9. cerebrum
    The largest group of commissural fibers in the brain; connects the right and left cerebral hemispheres.
  10. diencephalon
    (dy′-en-SEF-ah-lon) The central core of the brain; made up of the thalamus, hypothalamus, epithalamus, and subthalamus.
  11. dura mater
    (DOO-rah MAH-ter) The tough outermost meninx that surrounds the brain and the spinal cord.
  12. dural sinus superior sagittal sinus
    The set of venous channels that are located between two layers of dura mater and drain the cerebral veins of the brain.
  13. falx cerebri
    (seh-REE-bry) A double fold of meningeal dura that dives into the longitudinal fissure and separates the two cerebral hemispheres.
  14. fourth ventricle
    A hollow, cerebrospinal fluid–filled cavity located within the brainstem.
  15. frontal lobe
    The two anterior lobes of the cerebral hemispheres; responsible for planning and executing movement and complex mental functions.
  16. gray matter
    Collections of unmyelinated axons, dendrites, and cell bodies that appear gray
  17. hypothalamus
    The small anterior and inferior component of the diencephalon of the brain; responsible for many homeostatic functions, producing the hormones oxytocin and antidiuretic hormone, and producing releasing and inhibiting hormones that affect the anterior pituitary gland.
  18. insula
    (IN-syoo-lahz) Deep lobes of the cerebrum; have functions relating to taste and to viscera.
  19. lateral fissure
    A fissure on the lateral side of each cerebral hemisphere that separates the temporal lobes from the frontal and parietal lobes.
  20. lateral ventricle
    Hollow, cerebrospinal fluid–filled cavities located within the two cerebral hemispheres.
  21. frontal lobe
    The two anterior lobes of the cerebral hemispheres; responsible for planning and executing movement and complex mental functions.
  22. longitudinal fissure
    The deep groove that separates the two cerebral hemispheres.
  23. medulla oblongata
    The final portion of the brainstem.
  24. midbrain
    The first portion of the brainstem.
  25. Brocas area
    A premotor multimodal association area for speech located in the anterolateral frontal lobe; responsible for the ability to produce the motor actions necessary for language.
  26. occipital lobe
    The posterior lobes of the cerebrum; process all information relating to vision.
  27. optic chiasma
    An X-shaped structure formed by the meeting of the optic nerves at the midline; location where some of the axons of the optic nerve cross to the other side of the brain.
  28. parietal lobe
    Lobes of the cerebral hemispheres located posterior to the frontal lobes; responsible for processing and integrating sensory information, and also function in attention.
  29. pia mater
    The inner, delicate meninx that surrounds the brain and spinal cord.
  30. pons
    The middle portion of the brainstem.
  31. postcentral gyrus
    A gyrus located posterior to the central sulcus of each cerebral hemisphere in the parietal lobes; contains the primary somatosensory cortex.
  32. posterior root
    The extension from the posterior horn of the spinal cord containing the axons of somatic sensory neurons.
  33. posterior root ganglion
    The swollen area of the posterior root where the cell bodies of somatic sensory neurons are housed.
  34. precentral gyrus
    A gyrus located anterior to the central sulcus of each cerebral hemisphere in the frontal lobes; contains the primary motor cortex.
  35. spinal cord
    The organ of the central nervous system that connects the brain with the peripheral nervous system and performs certain integrative functions
  36. temporal lobe
    Cerebral lobes located on the lateral surface of the cerebrum; perform functions related to hearing, language, memory, and emotions.
  37. thalamus
    (THAL-ah-muss) The central and largest component of the diencephalon of the brain, consisting of two egg-shaped masses of gray matter; edits and sorts information entering the cerebrum.
  38. third ventricle
    A hollow, cerebrospinal fluid–filled cavity located in the center of the diencephalon.
