QUADRIGEMINAL BODIES Meaning and
Definition
-
Quadrigeminal bodies, also known as the corpora quadrigemina or tectal plate, are structures located in the midbrain of the central nervous system. Specifically, they are situated in the posterior part of the midbrain and are composed of four small rounded masses or eminences, which are arranged in two pairs. Each pair is referred to as a superior colliculus and an inferior colliculus, respectively.
The superior colliculi, which are the upper pair, play a significant role in visual processing. They receive visual sensory input from the eyes and are involved in the coordination of eye movements and visual reflexes. These reflexes include the ability to quickly orient the eyes towards a particular stimulus or to initiate a blinking response when exposed to a bright light.
On the other hand, the inferior colliculi, or lower pair, are primarily involved in auditory processing. They receive auditory information from the cochlear nuclei in the brainstem and relay it to higher brain regions involved in sound localization, auditory attention, and the processing of complex auditory stimuli.
Overall, the quadrigeminal bodies function as an integral part of the sensory processing pathway in the brain, coordinating visual and auditory information and relaying it to other brain regions for further processing and interpretation. They play a crucial role in various sensory-motor reflexes, which are essential for survival and adaptive behavior in response to sensory stimuli from the environment.

Etymology of QUADRIGEMINAL BODIES
The term "quadrigeminal bodies" is derived from the Latin word "quadri" meaning "four", and "gemina" meaning "twin" or "double". The plural form of "gemina" is "geminal". Therefore, "quadrigeminal" refers to something that is "fourfold" or "having four pairs". Lastly, "bodies" in this context refer to structures or masses within the brain.
