(Redirected from Frontal gyrus)

Frontal gyri are a part of the brain's cerebral cortex. They are located in the frontal lobe, which is the largest of the brain's four major lobes. The frontal gyri are divided into three parts: the superior frontal gyrus, the middle frontal gyrus, and the inferior frontal gyrus.

Etymology[edit | edit source]

The term "gyrus" comes from the Latin word for "circle" and is used in anatomy to describe a fold or ridge in the brain. The term "frontal" refers to the location of these gyri in the frontal lobe of the brain.

Superior Frontal Gyrus[edit | edit source]

The Superior Frontal Gyrus is the largest of the frontal gyri. It is involved in self-awareness and coordination of the body's movements.

Middle Frontal Gyrus[edit | edit source]

The Middle Frontal Gyrus is involved in working memory and decision making. It is also associated with personality traits and social behavior.

Inferior Frontal Gyrus[edit | edit source]

The Inferior Frontal Gyrus is involved in language processing and speech production. It is divided into three parts: the pars opercularis, the pars triangularis, and the pars orbitalis.
