Sulcal artery is a term used in anatomy to describe an artery situated in the sulcus. The pronunciation of this word can be understood using the International Phonetic Alphabet (IPA). The IPA transcription for the word "sulcal" is /ˈsʌlkəl/, which represents the sounds "s" as in "sit," "ʌ" as in "up," "l" as in "less," and "k" as in "keen." Together, the pronunciation of "sulcal" creates a very distinct sound that is easy to identify. Similarly, the IPA transcription for "artery" is /ˈɑrtəri/, which represents the sounds "ɑ" as in "father," "r" as trilled in some accents or alveolar flipped, "t" as in "tan," and "i" as in "machine."
A sulcal artery is a term used in anatomy and medicine to refer to an artery that courses within the sulci (grooves or furrows) of the brain's cerebral cortex. These arteries traverse the crevices and fissures on the surface of the brain, supplying oxygen-rich blood to the surrounding brain tissue.
Sulcal arteries are specifically responsible for irrigating the sulci, which are the narrow grooves that divide the brain's convoluted outer cortex into distinct ridges known as gyri. These arteries play a vital role in maintaining the cerebral blood flow required for proper brain function.
The sulcal artery systems are highly complex and interconnected, forming an intricate network with other arteries in the brain. They arise from larger arteries and branches of major cerebral arteries, such as the middle cerebral artery or the anterior cerebral artery.
Damage or pathology affecting the sulcal arteries can have serious implications for brain health. Conditions like stroke, aneurysm, or arterial rupture may disrupt the blood supply to the brain tissue in the sulci, leading to potentially severe consequences such as brain damage or impairment.
Understanding the anatomy and function of sulcal arteries is crucial in medical fields like neurosurgery, neurology, and radiology as it helps in diagnosing and treating various brain disorders and conditions.

The term "sulcal artery" is derived from the combination of two words: "sulcal" and "artery".
1. Sulcal: The word "sulcal" comes from the Latin word "sulcus", meaning "furrow" or "groove". It refers to the shallow groove or furrow on the surface of the brain, known as a sulcus, which separates two specific parts of the brain.
2. Artery: The word "artery" has its roots in the Latin word "arteria", meaning "air-carrying vessel" or "windpipe". It was used in ancient times to describe the blood vessels that seem empty when cut, as if they carried air rather than blood.
Thus, combining these two words, "sulcal artery" refers to an artery that runs within or alongside a sulcus (a groove or furrow) on the surface of the brain.
