'''Orbitofrontal artery''' is a branch of the [[ophthalmic artery]] that supplies blood to the [[frontal lobe]] of the [[brain]]. It is named for its location in the [[orbit]] of the skull, which houses the [[eye]] and its associated structures.

==Etymology==
==Orbitofrontal Artery==
The term "orbitofrontal" is derived from "orbit," referring to the eye socket, and "frontal," referring to the frontal lobe of the brain. The term "artery" comes from the Latin "arteria," meaning a vessel that carries blood from the heart to the body.
The '''orbitofrontal artery''' is a branch of the [[anterior cerebral artery]], which supplies blood to the [[orbitofrontal cortex]] of the [[brain]]. This artery plays a crucial role in delivering oxygenated blood to the frontal lobe regions involved in decision making, reward processing, and social behavior.


==Anatomy==

The orbitofrontal artery arises from the ophthalmic artery, which is itself a branch of the [[internal carotid artery]]. It travels through the orbit, supplying blood to the structures within, before reaching the frontal lobe of the brain.


==Function==
===Anatomy===
The primary function of the orbitofrontal artery is to supply blood to the frontal lobe of the brain. This region of the brain is responsible for a variety of functions, including [[motor skills]], problem solving, memory, language, and judgment.
The orbitofrontal artery typically arises from the A2 segment of the anterior cerebral artery. It courses anteriorly and inferiorly towards the orbitofrontal cortex, which is located on the ventral surface of the frontal lobe. The artery supplies the medial and inferior surfaces of the frontal lobe, including the gyrus rectus and the orbital gyri.


==Clinical significance==
===Function===
Damage to the orbitofrontal artery can lead to a variety of medical conditions, including [[stroke]], [[aneurysm]], and [[hemorrhage]]. It can also result in reduced blood flow to the frontal lobe, leading to cognitive and motor impairments.
The primary function of the orbitofrontal artery is to supply blood to the orbitofrontal cortex. This region of the brain is involved in various cognitive processes, including:

* [[Reward processing]]

* Impaired decision making

Orbitofrontal Artery[edit]

The orbitofrontal artery is a branch of the anterior cerebral artery, which supplies blood to the orbitofrontal cortex of the brain. This artery plays a crucial role in delivering oxygenated blood to the frontal lobe regions involved in decision making, reward processing, and social behavior.

Anatomy[edit]

The orbitofrontal artery typically arises from the A2 segment of the anterior cerebral artery. It courses anteriorly and inferiorly towards the orbitofrontal cortex, which is located on the ventral surface of the frontal lobe. The artery supplies the medial and inferior surfaces of the frontal lobe, including the gyrus rectus and the orbital gyri.

Function[edit]

The primary function of the orbitofrontal artery is to supply blood to the orbitofrontal cortex. This region of the brain is involved in various cognitive processes, including:

The orbitofrontal cortex integrates sensory information with reward values, which is essential for adaptive decision-making and behavior.

Clinical Significance[edit]

Damage or occlusion of the orbitofrontal artery can lead to deficits in the functions of the orbitofrontal cortex. Such deficits may manifest as:

  • Impaired decision making
  • Altered social behavior
  • Emotional dysregulation

In some cases, lesions in the orbitofrontal cortex due to vascular issues can result in orbitofrontal syndrome, characterized by disinhibition, impulsivity, and socially inappropriate behavior.
