Collateral fissure
Collateral Fissure
The Collateral Fissure (kəˈlætərəl ˈfɪʃər), also known as the collateral sulcus, is a prominent structure in the brain anatomy.
Etymology
The term "collateral" is derived from the Latin word collaterale, meaning "side by side". The term "fissure" comes from the Latin word fissura, meaning "a cleft or crack".
Anatomy
The Collateral Fissure is a deep sulcus (or groove) on the inferior surface of the brain, separating the parahippocampal gyrus from the lingual gyrus in the occipital lobe. It extends from near the occipital pole to the temporal pole, running parallel to and above the rhinal sulcus.
Function
The exact function of the Collateral Fissure is not fully understood. However, it is believed to play a role in the separation and processing of different types of sensory information in the brain.
