How Do You Spell FISSURA CALCARINA?

1. Fissura calcarina, also known as the calcarine sulcus or the calcarine fissure, is a structural feature located in the occipital lobe of the brain. It can be found on the medial surface of the brain where the occipital lobe meets the parietal lobe.

   The fissura calcarina is one of the major landmarks in the brain that divides the occipital lobe into two distinct regions: the cuneus and the lingual gyrus. It is characterized by a deep groove or indentation that runs horizontally and extends anteriorly from the occipital pole, ending near the parieto-occipital sulcus.

   This particular fissure plays a vital role in vision and visual processing. Within the fissura calcarina lies the primary visual cortex, also known as V1 or the striate cortex. This region is responsible for initial visual perception and interpretation of visual stimuli received from the eyes. It plays a crucial role in processing visual information such as color, shape, and motion.

   The presence of the fissura calcarina can vary among individuals, with variations in size and depth. Certain conditions like developmental abnormalities or brain lesions may alter the anatomy or structure of this fissure. Understanding the significance and location of the fissura calcarina is important in neuroanatomy, as it serves as a landmark for identifying and studying the various functions and interactions of the occipital lobe with other regions of the brain involved in visual processing.

2. Calcarine fissure, a deep fissure running in an arched form backward from the isthmus of the fornicate gyrus to the occipital pole, bounding the upper border of the lingual gyrus.

Common Misspellings for FISSURA CALCARINA

The term "fissura calcarina" has its etymology rooted in Latin and neuroscience.

The word "fissura" comes from the Latin word "fissura" meaning "a crack or a cleft". In anatomy, it refers to a natural division or separation between tissues.

"Calcarina" is derived from the Latin word "calcar" meaning "spur" or "heel". In neuroscience, it specifically refers to the calcarine sulcus, a prominent anatomical structure on the occipital lobe of the brain.

Therefore, "fissura calcarina" can be understood as the "fissure or cleft that is associated with the calcarine sulcus". This term is commonly used in neuroanatomy to describe the division between the upper and lower visual areas of the brain located in the occipital lobe.
