Superior frontal sulcus
Superior Frontal Sulcus
The Superior Frontal Sulcus (pronunciation: su·pe·ri·or fron·tal sul·cus) is a sulcus (groove) in the brain that separates the superior frontal gyrus from the middle frontal gyrus.
Etymology
The term "Superior Frontal Sulcus" is derived from Latin. "Superior" means upper, "Frontal" refers to the frontal lobe of the brain, and "Sulcus" is a term used in anatomy to denote a groove or furrow.
Anatomy
The Superior Frontal Sulcus runs anteriorly from the precentral sulcus, but does not reach as far as the frontal pole. It is one of the most consistent sulci of the brain and is present in all normal brains. It is parallel to and above the inferior frontal sulcus, and together they divide the lateral surface of the frontal lobe into the superior, middle, and inferior frontal gyri.
Function
The Superior Frontal Sulcus is part of the prefrontal cortex, which is involved in a variety of functions including decision making, personality expression, and moderating social behavior.
