Where is the trigeminal nerve located?

Are you someone who loves to get lost in the world of science? Do big scientific words make you dizzy with excitement? If yes, then buckle up my friend because we are about to embark on a journey where we explore one of the most interesting nerves in our body – The Trigeminal nerve!


Our bodies are like machines. They work tirelessly without any breaks and keep us alive day after day. However, ever wondered how these machines function so flawlessly? Well, there’s no one answer for that question but let me tell you something; it all starts with nerves.

Nerves are like wires connected inside our system that facilitate communication between different parts of the body. And trigeminal nerve happens to be one such net-like structure which branches out into three divisions before it reaches its destination points.

What is a Trigeminal Nerve?

The trigeminal nerve, also known as CNV or fifth cranial nerve (in Latin physician terms) originates from the brainstem and divides into three major branches: Ophthalmic branch (V1), Maxillary branch (V2), Mandibular branch(V3). Each division carries sensory and motor signals from specific regions of our face and head area. 

With this introduction covered briefly, let’s jump right into understanding where this remarkable nerve lies:


Tracing nerves often requires good knowledge regarding human anatomy as they traverse through challenging spaces inside your skull case or even sometimes sending their tendrils way down legs!

This holds particularly true for Our dear born superstar- Trigeminal Nerve! It makes its way out from behind your jaw bone close to your ear (Jawbone junction) course through cavities along with bones until reaching target areas issuing pain & temperature responses within eye sockets cheeks mouth lips chin nasal cavities etc. 

But it doesn’t stop there, from the face alone the V3 branch of Trigeminal nerve also covers large areas along with tongue, ears, upper and lower teeth as well! Yet despite its massive branches invasion, it all originates from a tiny portion called Pons inside the brainstem’s dorsal section.

Now to be completely honest here – understanding this on your own can feel like eating glass shards for breakfast. Hence we created reminders in our daily life connections that would assist you subconsciously connect where this “trolling nerve” may reside.

A Drill Down into Specifics

Do I have any readers who are visual learners? Okay great! Let’s go through some different ligamentous structures and crannies where each branch passes through and their respective associated important anatomical landmarks:

Branches Foramen/Canal/Cavity Passed Through Associated Anatomy
V1 Superior Orbital Fissure Orbital content such as muscles or veins carrying blood
V2 Foramen Rotundum Maxillary bone/nasal cavity/petrotympanic fissure/pharyngeal tubercle
V3 Foramen Ovale/Lower petrosal groove and Mandibular canal

Whew! That was a lot right there. But hey knowledge is power but when you add humor to factual nuggets –👋! Don’t worry, we’ll break it down even furtherall trio branches traverse across different cranial cavities and foramen (_holes) inside your skull. All in all making this little known fella a key to any oral health gory tale you wish to narrate.


Boom! That’s pretty much where this little mischievous cat lives. So next time when someone pops the question, “where is the trigeminal nerve located?” You know precisely what that conniving little chap is up to; hijacking every nook and cranny of our face with its three-pronged apparatus.

Nevertheless, if just saying ” Trigeminal Nerve” makes your head spin –fear not as knowledge is always a slippery thing whether grilled or humorously sliced (in my norm).  Now When I leave you here cake walking on how Trigeminal nerve behaves hope they make an interesting party starter topic!


Just kidding there aren’t any references since they are highly overrated these days #Roadnottaken
