Perihypoglossal nuclei

Perihypoglossal nuclei (also perihypoglossal complex, perihypoglossal nuclear complex, or satellite nuclei) are three prominent groups of neurons in the caudal medulla oblongata near the hypoglossal nucleus:^: 449.e1 the nucleus prepositus hypoglossi, intercalated nucleus, and sublingual nucleus. They are involved in controlling eye movements: they send their principal projections to the three cranial nerve nuclei controlling extrinsic eye muscles via the medial longitudinal fasciculus.
