One of a pair of motor nerves, the fourth and smallest cranial nerve, essential for eye movement.<\/p>\n
The fourth cranial nerve (IV),\u00a0which supplies the superior oblique muscle,\u00a0one of the muscles responsible for\u00a0movement of the eyeball in its socket. The\u00a0action of the trochlear nerve is coordinated\u00a0with that of the oculomotor and abducens\u00a0nerves.<\/p>\n
The fourth cranial nerve (arising from the brain), which acts upon the superior oblique muscle of the eye.<\/p>\n
The fourth cranial nerve, a small mixed nerve arising from the midbrain. It is both sensory and motor to the superior oblique muscle of the eye.<\/p>\n
The trochlear nerve is the fourth cranial nerve, and there are two of them originating in the brainstem, one on either side of the midbrain. These nerves pass through openings in the skull bones to reach the eye sockets. Each trochlear nerve governs one of the two superior oblique muscles, which facilitate the downward and outward rotation of the eyes.<\/p>\n
