Across
  1. 2. Ascending pathway relaying discriminative pain information to the somatosensory cortex
  2. 5. Acceleration communicated through the otolith organs (ultricle and saccule), with otoconia-topped membranes in maculae (vestibular)
  3. 6. Voluntary motor function system from Areas 4 and 6 to skeletal muscle via efferent neurons
  4. 9. Thoracolumbar structure containing sympathetic preganglionic neurons
  5. 10. Connects the cerebral cortex to the brainstem, enabling control of facial muscles, enabling speech etc
Down
  1. 1. Set of three pathways: vestibulospinal (head posture), tectospinal (orienting response), and reticulospinal (antigravity reflex)
  2. 3. Parasympathetic outflow through preganglionic neurons in the brainstem and spinal cord
  3. 4. Ascending pathway through the dorsal column relaying proprioceptive stimuli to the somatosensory cortex
  4. 7. This system contains the cochlear Organ of Corti (tectorial membrane etc), between the scala media and tympani
  5. 8. Acceleration communicated through the semicircular canals, with the ampulla containing cupula and endolymph (vestibular, nystagmus)
