The angular gyrus is located at the posterior end of the superior temporal sulcus as a connecting gyrus between the superior temporal gyrus and middle temporal gyrus.
Blood supply
The blood supply to the angular gyrus is provided by a terminal branch of the middle cerebral artery.
Function
The angular gyrus is part of the higher-order association areas of the cerebral cortex. It plays a crucial role in connecting higher-order visual and auditory centers with higher-order sensory and motor areas. Thus, it is critically involved in functions such as writing, reading, and arithmetic1. In the dominant hemisphere, the angular gyrus is part of Wernicke's language area. The precise localization of the language area varies between individuals2.
