It is classified as a muscle of the posterior brachium. Its inferior brachium (arm-like process) reaches to the medial geniculate nucleus of the diencephalon. Claude's syndrome affects oculomotor nerve, red nucleus and brachium conjunctivum. The median nerve has no voluntary motor or cutaneous function in the brachium. "brachium" meaning "arms" or in this case "toes". They are named from the Latin term for the superior cerebellar peduncle, the "brachium conjunctivum".
