Q: Identify the nerve marked with an arrow in the given section of cranial cavity.

Abducens. ***Abducens*** - The image shows the abducens nerve passing through **Dorello's canal** on its way to the **cavernous sinus**. - Its unique path makes it susceptible to injury in cases of increased intracranial pressure, leading to **lateral rectus palsy**. *Trochlear* - The trochlear nerve is the **smallest cranial nerve** and exits the brainstem dorsally, then wraps around to the ventral side. - It innervates the **superior oblique muscle** of the eye. *Trigeminal* - The trigeminal nerve is a large cranial nerve with **three main divisions** and is responsible for sensations in the face and motor functions like chewing. - It arises more laterally from the pons and is typically seen entering the **Meckel's cave**. *Oculomotor* - The oculomotor nerve emerges from the **midbrain** and controls most of the extrinsic eye muscles and pupillary constriction. - It is usually visible superior to the abducens nerve in the **cavernous sinus**. *Facial* - The facial nerve exits the brainstem at the **cerebellopontine angle** and enters the **internal acoustic meatus** with the vestibulocochlear nerve. - It controls muscles of **facial expression** and carries taste sensation from the anterior two-thirds of the tongue.
