Anatomy - The trochlear nucleus is located in the midbrain, specifically in the caudal rostral region. - It is positioned between the superior colliculus and inferior colliculus. - The trochlear nucleus is situated near the midline of the brain. - It is embedded within the medial longitudinal fasciculus. - The trochlear nucleus is located below the nucleus of the oculomotor nerve.

Blood supply - The trochlear nucleus receives arterial blood supply from the posterior cerebral artery, superior cerebellar artery, and basilar artery. - Disruption of blood flow through these vessels can affect the blood supply to the trochlear nucleus.

Related structures - The trochlear nerve is related to the trochlear nucleus.
