In the medulla oblongata, the arcuate nucleus is a group of neurons located on the anterior surface of the medullary pyramids. These nuclei are the extension of the pontine nuclei.[1]
They receive afferents from the corticospinal tract.[citation needed]
They in turn project efferents into the cerebellum through the inferior cerebellar peduncle as:[1]
Function
Arcuate nuclei are capable of chemosensitivity and have a proven role in the respiratory center controlling the breathing rate.[2]
