FISSURA PETROSQUAMOSA Meaning and Definition

1. The term "fissura petrosquamosa" refers to a specific anatomical feature found in the human skull. It is a narrow opening located between two bones, namely the petrous part of the temporal bone and the squamous part of the temporal bone.

   The petrous part of the temporal bone is a pyramid-shaped structure located at the base of the skull. Its primary function is to encase and protect the delicate structures of the inner ear, including the hearing and balance organs. The squamous part of the temporal bone, on the other hand, forms the flat upper portion of the skull, contributing to the sides and base of the cranium.

   The fissura petrosquamosa serves as a pathway for certain important blood vessels and nerves. Specifically, it allows the passage of the middle meningeal artery, a branch of the maxillary artery derived from the external carotid artery. This artery provides oxygenated blood to the meninges, the protective membranes that surround the brain and spinal cord.

   Additionally, the fissura petrosquamosa accommodates the main trunk of the meningeal branch of the mandibular nerve, also known as V3. This nerve is part of the trigeminal nerve, one of the major cranial nerves responsible for sensing facial touch, pain, and temperature.

   Overall, the fissura petrosquamosa is a small but significant anatomical structure that facilitates the passage of crucial blood vessels and nerves, ultimately contributing to the proper functioning of the brain and other associated structures.

2. A shallow fissure indicating externally the line of fusion of the petrous and squamous portions of the temporal bone.
