Cerebral Penduncles (Human)

  • Part of the mesenchephalan (midbrain)
  • Peduncles = tracts (nerve fibers/bundles)
  • Connects the lower brain to the higher brain
  • *Carried information from the lower to the higher part of the brain

Corpora Quadrigemina (Human)

  • Involuntary eye and ear reflexes
  • Eye reflexes include blinking, dilating & constricting pupul
  • Ear reflexes include ringling, muffles, and turning ear to sound

Decussation of Pyramids (Human) 

  • Located on the medulla oblongata
  • Crossing over of nerve tracts
  • Ex: Right side of the brain crosses over to the left side of the body
  • Ex: Left side of the brain crosses over to the right side of the body
