Brain Stem Flashcards
1
Q
A
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

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

Q
A
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
