ARTERIA CALCARINA Meaning and
Definition
-
Arteria calcarina, also known as the calcarine artery, is a major blood vessel located within the brain. It is a branch of the posterior cerebral artery (PCA), which is responsible for supplying oxygenated blood to the posterior part of the brain.
The arteria calcarina is specifically responsible for providing blood supply to the occipital lobe of the cerebral cortex. This region is primarily associated with processing visual information and plays a vital role in vision and visual perception.
The calcarine artery follows a specific course within the brain. It typically arises from the posterior cerebral artery and courses along the medial surface of the brain, remaining within the calcarine sulcus. This sulcus is a prominent, curved groove located on the medial occipital lobe.
Due to its location and function, any disruption or occlusion of the arteria calcarina can have significant consequences for vision. Reduced blood flow to the occipital lobe can lead to visual impairments, such as partial or complete blindness, depending on the extent and duration of the blood supply interruption.
Understanding the anatomy and functionality of the arteria calcarina is crucial for diagnosing and treating conditions that affect the occipital lobe, such as strokes, aneurysms, or other vascular disorders. Medical professionals, particularly neurologists and radiologists, rely on this knowledge to interpret imaging studies, identify abnormalities, and plan appropriate interventions to restore or preserve visual function.

Etymology of ARTERIA CALCARINA
The word "arteria calcarina" is of scientific origin and comes from Latin and Greek.
The term "arteria" derives from the Latin word "arteria", which means artery. This Latin term originates from the Greek word "ἀρτηρία" (artería), which also means artery.
The word "calcarina" is derived from the Latin word "calcar", meaning spur or spur-like process. The suffix "-ina" is used to form adjectives in Latin, indicating that it is related to a spur.
Therefore, "arteria calcarina" refers to an artery that has a spur-like process, which is a term commonly used in anatomy to describe a branch of the posterior cerebral artery that supplies the calcarine cortex, responsible for visual perception, in the brain.
