FISSURA PETROOCCIPITALIS Meaning and Definition

1. Fissura petrooccipitalis refers to a narrow, elongated opening situated between the petrous part of the temporal bone and the occipital bone in the skull. This anatomical feature is commonly found within the human skull.

   The fissura petrooccipitalis, also known as the petro-occipital fissure, is located on the lower surface of the skull, close to the junction between the temporal and occipital bones. It serves as a passageway for important structures that travel through the skull.

   This fissure provides a pathway for the passage of the ninth, tenth, and eleventh cranial nerves. These nerves, known as the glossopharyngeal, vagus, and accessory nerves respectively, have various functions related to the throat, head, and neck region. The fissura petrooccipitalis allows these nerves to enter and exit the skull, along with associated blood vessels.

   The presence and position of the fissura petrooccipitalis play a crucial role in the study of skull anatomy, as it assists in identifying and understanding the spatial relationship between these nerves, blood vessels, and the surrounding structures. Furthermore, it may also have implications in certain surgical procedures in the head and neck region, as a comprehensive understanding of its location can help prevent potential nerve or vascular damage.

   In summary, the fissura petrooccipitalis is a small and narrow opening located between the temporal and occipital bones in the skull. It functions as a conduit for the passage of vital cranial nerves and associated blood vessels, influencing the anatomy and clinical management of the head and neck region.

2. Occipital fissure, a fissure passing backward from the foramen lacerum between the outer side of the basioccipital and the posterior and inner border of the petrous portion of the temporal bone.

Etymology of FISSURA PETROOCCIPITALIS

The term "fissura petrooccipitalis" is composed of two Latin words: "fissura" and "petrooccipitalis".

The word "fissura" comes from the Latin verb "findere", which means "to split or cleave". It is derived from the Proto-Indo-European root *bʰeyd-, meaning "to split".

The word "petrooccipitalis" is a combination of two words: "petrous" and "occipitalis". "Petrous" comes from the Latin word "petrosus", meaning "rock-like" or "hard". It refers to the petrous bone, which is part of the temporal bone in the skull.
