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.

The frontal gyri are typically divided into three main regions: the [[superior frontal gyrus]], the [[middle frontal gyrus]], and the [[inferior frontal gyrus]].
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==
== Superior Frontal Gyrus ==
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==
The [[superior frontal gyrus]] is located at the top of the frontal lobe and extends from the [[frontal pole]] to the [[precentral gyrus]]. It is involved in self-awareness and in the coordination of complex cognitive tasks. The superior frontal gyrus is also associated with working memory and the control of attention.
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.

Frontal Gyri[edit]

Frontal gyri lateral view

The frontal gyri are a group of gyri located in the frontal lobe of the human brain. These gyri are involved in various high-level brain functions, including cognition, decision making, and voluntary movement. The frontal gyri are typically divided into three main regions: the superior frontal gyrus, the middle frontal gyrus, and the inferior frontal gyrus.

Superior Frontal Gyrus[edit]

The superior frontal gyrus is located at the top of the frontal lobe and extends from the frontal pole to the precentral gyrus. It is involved in self-awareness and in the coordination of complex cognitive tasks. The superior frontal gyrus is also associated with working memory and the control of attention.

Middle Frontal Gyrus[edit]

Gyri of lateral cortex

The middle frontal gyrus lies between the superior and inferior frontal gyri. It plays a crucial role in executive functions, such as planning, problem-solving, and the regulation of emotions. The middle frontal gyrus is also involved in the processing of language and the integration of sensory information.

Inferior Frontal Gyrus[edit]

The inferior frontal gyrus is located below the middle frontal gyrus and is divided into three parts: the pars opercularis, pars triangularis, and pars orbitalis. This region is critical for language production and comprehension, particularly in the left hemisphere where it forms part of Broca's area. The inferior frontal gyrus is also involved in the processing of risk and reward, as well as in the inhibition of inappropriate responses.

Function and Importance[edit]

The frontal gyri are essential for the execution of complex cognitive tasks and the regulation of behavior. They are involved in the integration of sensory information, decision-making processes, and the control of voluntary movements. Damage to these areas can result in deficits in executive function, language disorders, and changes in personality and behavior.
