The term "sulcus basilaris" refers to the groove found in the posterior surface of the medulla oblongata. It is often pronounced as /ˈsʌlkəs bəˈsɪlərɪs/ where the first syllable, "sulcus", sounds like "sulk-us" and the second syllable, "basilaris", is pronounced as "buh-sil-uh-ris". The IPA phonetic transcription helps explain the spelling of the word, highlighting the stress on the first syllable and the pronunciation of the "s" sounds. Proper spelling of medical terms is critical to ensure accurate communication in the healthcare field.
The term "sulcus basilaris" refers to a specific anatomical feature of the brain. It is derived from the Latin word "sulcus," meaning groove, and "basilaris," relating to the basilar artery that runs along the midline of the brainstem. This sulcus is also known as the basilar sulcus.
The sulcus basilaris is a deep groove located on the ventral (underside) surface of the brainstem, extending from the midbrain to the medulla oblongata. It serves as a landmark to demarcate the boundary between the pons, which is anterior to it, and the medulla oblongata, which is posterior to it.
This anatomical structure is formed by the course of the basilar artery as it travels along the ventral surface of the brainstem, giving rise to several arterial branches that supply blood to various structures of the brain, including the cerebellum, pons, and medulla. It represents an important landmark for neurosurgeons and radiologists when assessing imaging studies or performing surgical procedures in this region.
In summary, the sulcus basilaris is a deep groove on the ventral surface of the brainstem, formed by the basilar artery, and serves as a boundary between the pons and medulla oblongata. Its location and relation to major blood vessels make it a significant anatomical landmark in neurosurgery and radiology.
Basilar groove, a mesial groove on the ventral surface of the pons Varolii in which lies the basilar artery.
