Corpora Quadrigemina

Corpora Quadrigemina (pronunciation: /kɔːrˈpoʊrə kwɑːdrɪˈdʒɛmɪnə/) is a term in neuroanatomy that refers to the four colliculi—two inferior and two superior—that are part of the midbrain.

Etymology

The term "corpora quadrigemina" is derived from Latin, where "corpora" means "bodies" and "quadrigemina" means "quadruplets". This term is used due to the four rounded eminences, or colliculi, present in the midbrain.

Function

The superior colliculi are involved in preliminary visual processing and control of eye movements. On the other hand, the inferior colliculi are part of the auditory pathway and are involved in the subconscious processing of auditory information.

Related Terms

  • Midbrain: The part of the brain where the corpora quadrigemina is located.
  • Colliculus: A small protuberance in the brain, two pairs of which form the corpora quadrigemina.
  • Superior colliculus: One of the four colliculi, involved in visual processing.
  • Inferior colliculus: One of the four colliculi, involved in auditory processing.
