The Trigeminal Nerve is located in a structure in the brain stem called the pons.
The trigeminal nerve has three branches: the ophthalmic, maxillary, and mandibular. The trigeminal nerve branches from the skin and mucous membrane of head and from teeth to brain; also from brain to chewing muscles. It's functions are to control sensations of the face, scalp, and teeth; chewing movements.
V1 - Opthalmic = sensory nerve
V2 - Maxillary = sensory nerve
V3 - Mandibular = mixed nerve, i.e. both sensory and motor
The trigeminal nerve is one of twelve so-called "cranial nerves" - so-called because unlike other peripheral nerves that originate from the part of the spinal cord that is contained within the spinal column (like cervical nerves, for example), they originate inside the cranium or skull. The trigeminal nerve is the fifth cranial nerve, and is sometimes referred to as CN-V. It is called "trigeminal" (Latin for "three twins") because it separates into three branches soon after it exits the skull. Its upper branch is called the ophthalmic branch, the middle branch is the maxillary branch, and its lower branch is the mandibular branch. It is largely responsible for carrying sensory information from the face back to the brain, but has some other roles as well.
The facial nerve is the seventh cranial nerve (denoted as CN VII). It has a total of 11 branches which are unofficially classed into 3 groups
1. Branches in the facial canal
2. Branches before exiting the stylomastoid foramen
3. Branches after exiting the stylomastoid foramen
The branches of the third group (after exiting the stylomastoid foramen) are considered to be the "major" branches or "brachiomotor" component of the facial nerve
As indicated by it's name, the trigeminal nerve has three branches: ophthalmic, maxillary, and mandibular.
The five major branches of the facial nerve are:
Cervical
branches of the facial nerve
The facial muscles are innervated by facial nerve (cranial nerve VII). In contrast, the nearby masticatory muscles are innervated by the mandibular nerve, a branch of thetrigeminal nerve (V).

Facial nerve is the 7th cranial nerve. It has an Intracranial and extracranial course. So branches must be named accordingly as: Branches in the cranial cavity Branches outside the cranial cavity I will post the answer after 2 days...till then the reader can ponder on the question
You are speaking of the 12 cranial nerves:I. Olfactory nerve which branches out of the telencephalonII. Optic which branches out of the diencephalonIII. Oculomotor nerve which branches out of the mesencephalonIV. Trochlear nerve nerve which branches out of the mesencephalonV. Trigeminal nerve which branches out of the ponsVI. Abducens nerve which branches out of the ponsVII. Facial nerve which branches out of the ponsVIII. Vestibulochochlear nerve which branches out of the ponsIX. Glossopharangeal nerve nerve which branches out of the medullaX. Vagus nerve nerve which branches out of the medullaXI. Accessory nerve nerve which branches out of the medulla & cervical spineXII. Hypoglossal nerve nerve which branches out of the medulla
Greater petrosal nerve is where the nerve branches, so this would be around your inner ear region I believe.
The Facial Nerve or Cranial Nerve VII is the nerve involved with Bell's Palsy.
Smiling is an action produce by more than one muscle but the nerve that allows you to do that is the facial nerve (7th cranial nerve). Facial nerve has 5 branches and the action of all 5 allows you to smile nicely. The temporal branch allow you to wrinkle your forehead, the zygomatic branch allows you to partially close your eyes, the buccal branch allow you to elevate your chin, and the marginal mandibular allow you to widen your mouth laterally.
The facial muscles are innervated by facial nerve (cranial nerve VII). In contrast, the nearby masticatory muscles are innervated by the mandibular nerve, a branch of thetrigeminal nerve (V).
All muscles of facial expression are supplied by seventh cranial nerve. That is Facial nerve. This nerve carries the taste sensation from anterior two third of the tongue also.
Facial Nerve (VII)
Facial nerve, the seventh cranial nerve. It leaves the brain along with eighths cranial nerve through internal acoustic meatus and comes out through stylomastoid foramen to supply the muscles of facial expression.
Seems that infection from the root canal of the teeth have passed to your maxillary sinus near your facial nerve branches. Better consult your physician.
