The spelling of "eminentia collateralis" might seem daunting, but it follows the rules of Latin pronunciation. The word is pronounced /ɛˈmɪnəntiə kəˈlætərəlɪs/, with the emphasis on the second syllable of both words. The "e" in "eminentia" is pronounced like the "e" in "pet," and the "i" is pronounced like the "i" in "bit." The double "l" in "collateralis" is pronounced as a single "l," and the final "is" is pronounced with a short "i" sound.
Eminentia collateralis is a Latin term that refers to a specific anatomical feature of the brain known as the collateral eminence in English. The collateral eminence is a small raised area located on the ventricular surface of the brain's temporal lobe.
This defining feature is typically found in the lateral ventricle of the brain, more specifically within the inferior horn. The approximate location of the eminentia collateralis is near the junction of the inferior horn and the body of the lateral ventricle.
The term "eminentia" can be translated as "eminence" or "prominence," while "collateralis" refers to its position or relation to the neighboring structures. Hence, eminentia collateralis can be thought of as a prominent structure situated alongside other brain areas.
Although the precise function of the eminentia collateralis is not fully understood, it is believed to be associated with the formation and regulation of cerebrospinal fluid (CSF). CSF is a vital fluid that surrounds and protects the brain and spinal cord, providing cushioning and nutrients. The eminence might also play a role in facilitating the exchange of substances between the brain tissue and the CSF.
In conclusion, the "eminentia collateralis" is a Latin term referring to the collateral eminence, an anatomical feature located in the lateral ventricle's inferior horn. Its specific function is not fully known, but it is likely involved in CSF regulation and the exchange of substances within the brain.
Collateral eminence, an elevation on the floor of the collateral trigone of the lateral ventricle of the brain, between the hippocampus and the calcar avis, caused by the proximity of the bottom of the mid-collateral fissure; called also the posterior collateral eminence. The anterior collateral eminence is an elevation occasionally present on the floor of the inferior horn of the lateral ventricle, caused by the proximity of the anterior portion of the collateral fissure when this is present.
