SULCUS PETROSUS SUPERIOR Meaning and Definition

1. The term "sulcus petrosus superior" refers to a shallow groove found on the superior surface of the petrous part of the temporal bone within the human skull. The petrous part of the temporal bone is known for its dense and hard structure, contributing to the formation of the skull base.

   The sulcus petrosus superior runs along the length of the petrous part of the temporal bone, dividing it into two distinct regions. This groove is located on the superior aspect of the petrous part, which means it is towards the upper part of this portion of the temporal bone.

   The sulcus petrosus superior serves as a landmark for various structures and functions within the skull. It acts as a pathway and provides passage for important neurological structures, including the greater petrosal nerve. This nerve is involved in the transmission of parasympathetic fibers, which control certain functions such as lacrimation (tear production) and salivation.

   Additionally, the sulcus petrosus superior is also responsible for creating an indentation that accommodates the middle meningeal artery. This blood vessel supplies blood to the brain and its surrounding structures.

   Overall, the sulcus petrosus superior plays a crucial role in protecting and supporting important anatomical structures within the skull, as well as facilitating their proper functioning.

2. Superior petrosal groove, a groove on the superior border of the petrous portion of the temporal bone in which rests the superior petrosal sinus.
