fourth cranial nerve
The fourth cranial nerve, also known as the trochlear nerve, is one of the twelve cranial nerves in the human body. It is a motor nerve (a nerve that carries messages away from the brain and towards the muscles) that primarily functions to control the superior oblique muscle of the eye, allowing for eye movements and coordination. This nerve plays a crucial role in looking down and inwards, contributing significantly to eye movement and visual focus. It is the smallest and longest cranial nerve, as well as the only one to emerge from the back of the brainstem, making it unique among the cranial nerves.
