Angular gyrus at a glance
- What it is
- The angular gyrus is a cortical region of the inferior parietal lobule that arches over the end of the superior temporal sulcus.
- Location
- It lies in the posterior part of the inferior parietal lobule at the junction of the parietal, temporal and occipital lobes, corresponding to Brodmann area 39.
- Function
- It is an association area involved in language, especially reading and written language, as well as number processing and spatial attention.
- Body system
- Nervous · paired (left and right)
- FMA ID
- FMA72670 (Foundational Model of Anatomy)
Key facts
- Lies posterior to the supramarginal gyrus.
- Blood supply is mainly from the middle cerebral artery.
Clinical relevance
Lesions of the dominant-hemisphere angular gyrus are associated with alexia with agraphia and features of Gerstmann syndrome.
