1. Trochlear nerve

   The trochlear nerve (), (lit. pulley-like nerve) also known as the fourth cranial nerve, cranial nerve IV, or CN IV, is a cranial nerve that innervates a single muscle - the superior oblique muscle of the eye (which operates through the pulley-like trochlea). Unlike most other cranial nerves, the trochlear nerve is exclusively a motor nerve (somatic efferent nerve). The trochlear nerve is unique among the cranial nerves in several respects:

1. trochlear nerve

   The trochlear nerve is one of the twelve cranial nerves in the human body, specifically the fourth one. Its primary function is to control the superior oblique muscle of the eye, which is responsible for downward, upward, and outward eye movement. It is the smallest and has the longest pathway of the cranial nerves, emerging at the back of the brainstem and passing through the eye socket to reach the eyes. Defects to this nerve can result in a condition known as trochlear nerve palsy, which leads to difficulty moving the eyes properly.

1. Trochlear nerve

   The trochlear nerve is a motor nerve that innervates a single muscle: the superior oblique muscle of the eye. The trochlear nerve is unique among the cranial nerves in several respects. It is the smallest nerve in terms of the number of axons it contains. It has the greatest intracranial length. Other than the optic nerve, it is the only cranial nerve that decussates before innervating its target. Finally, it is the only cranial nerve that exits from the dorsal aspect of the brainstem. Homologous trochlear nerves are found in all jawed vertebrates. The unique features of the trochlear nerve, including its dorsal exit from the brainstem and its contralateral innervation, are seen in the primitive brains of sharks. The human trochlear nerve is derived from the basal plate of the embryonic midbrain.
