Explanation: 

Detailed explanation-1: -The trigeminal nerve is the part of the nervous system responsible for sending pain, touch and temperature sensations from your face to your brain. It’s a large, three-part nerve in your head that provides sensation.

Detailed explanation-2: -The ophthalmic nerve is the first branch of the trigeminal nerve, which is also known as the fifth cranial nerve. The ophthalmic nerve supplies sensory innervation to the structures of the eye, including the cornea, ciliary body, lacrimal gland, and conjunctiva.

Detailed explanation-3: -The three divisions of the nerve carry pain, temperature, and touch modalities from the skin of the face; the mucosa of sinuses, nose, and mouth; the teeth; and portions of the dura. They convey proprioceptive sensation from the teeth, hard palate, temporomandibular joint, and muscles of mastication.

Detailed explanation-4: -Sensation on the face is innervated by the trigeminal nerves (V) as are the muscles of mastication, but the muscles of facial expression are innervated mainly by the facial nerve (VII) as is the sensation of taste.
