  • (19) Aromatase immunoreactive cells (ARO-ir) were found in the medial preoptic nucleus, in the septal region, and in a large cell cluster extending from the dorso-lateral aspect of the ventromedial nucleus of the hypothalamus to the tuber at the level of the nucleus inferioris hypothalami.
  • (20) When outcome was examined in patients who were stuporous or comatose on admission, a significant increase in septal shift was found among patients with a poor outcome, but there was no significant relationship between outcome and degree of pineal or aqueductal shift.

Septum


Definition:

  • (n.) A wall separating two cavities; a partition; as, the nasal septum.
