Raises four domelike protrusions on the dorsal mid-brain surface. The superior pair, the superior colliculus are visual reflex centers that coordinate head and eye movements when visually following a moving object even if not consciously knowing you are doing so. The inferior pair, the inferior colliculusare part of auditory relay from hearing receptors of the ear to the sensory cortex. They also act in reflexive responses to sound, such as the startle reflex which causes you to turn your head toward an unexpected noise.

Damage to the corpora quadrigemina in the midbrain would impair?
vision and hearing
What part of the brain coordinates visual and auditory reflexes?
They are both located in the corpora quadrigemina.
Which part of the midbrain is responsible for hearing and visual reflexes?
Cerebrum That is a pretty broad area, true that the occipital lobe of the cerebrum is our vision center and the temporarl lobe houses our auditory center, neither of these necessarily controls our reflexes of these senses. I believe the answer that they were looking for is the corpora quadrigemina, part of the midbrain that contains the superior colliculi and the inferioror colliculi, which help us react to/analyze visual and auditory sensations that we encounter
What part of the corpora quadrigemina is clearly observed in a midsagittal section?
In primates the superior colliculus controls the automatic saccades (brain commands sent to the eye muscles result in the eyes making a rapid step-like rotation following which the eyes remain stationary). These step movements are known as saccades or saccadic eye movements and puts the retina in position to analyze sudden movements across the retina. Perhaps watching a fly.
What is corpora adiposa?
it is the stored fats..
What contains reflex centers for vision and hearing?
Corpora quadrigeminaCorpora quadrigemina
In the brain that is composed of four colliculi?
Yes. The landmark of the midbrain is the corpora quadrigemina. The corpora quadrigemina are two inferior colliculi and two superior colliculi.
Located in midbrain and contains reflex centers for vision and audition?
located in the midbrain; contains flex centers for vision and audition - Corpora quadrigemina.
What is the largest nuclear mass in the midbrain?
corpora quadrigemina
What 4 structures make up the Corpora Quadrigemina?
Corpora quadrigemina is located in mesencephalon (midbrain). It lies above and in front of the anterior medullary velum and superior peduncle, and below and behind the third ventricle and posterior commissure.
Is the superior colliculi of the corpora quadrigemina visual reflex centers?
True
Damage to the corpora quadrigemina in the midbrain would impair?
vision and hearing
What in the brain contains reflex centers for vision and audition?
Corpora quadrigeminaCorpora quadrigemina
Where are the reflexes such as blinking and pupil reflex centered at?
superior colliculi of corpora quadrigemina
What are the locations and specific anatomy of the corpora quadrigemina?
The copora quadrigemina is located inferior (belolw) the pineal gland in a portion of the brain called the mesencephalon a.k.a. the midbrain.
What part of the brain coordinates visual and auditory reflexes?
They are both located in the corpora quadrigemina.
What is the function of the corpora quadrigemina?
it houses the superior and inferior colliculi; the superior colliculi is related to vision while the inferior colliculi is related to sound.
