Trigeminal nerve The trigeminal nerve (the fifth cranial nerve, or simply CN V) is a nerve responsible for sensation in the face and motor functions such as biting and chewing.he sensory function of the trigeminal nerve is to provide tactile, proprioceptive, and nociceptive afference to the face and mouth. Its motor function activates the muscles of mastication, the tensor tympani, tensor veli palatini, mylohyoid and the anterior belly of the digastric.

TMJ and Trigeminal Nerve TMJ and Trigeminal Nerve. The temporomandibular joint (TMJ or TM Joint) and the trigeminal nerves are some of the most important structures of the face. When the TMJ is out of alignment or compromised in other ways, it can affect many other areas of the head and neck. Because the trigeminal nerve, which innervates the TMJ, also innervates so much of the face and neck, pain all over the head and face may result when there is any sort of disorder in this important structure. TMJ.

Trigeminal Nerve (Cranial Nerve V) The trigeminal nerve sensory and motor roots exit the brainstem from the ventrolateral pons. It then enters Meckel's cave located posterior and inferolateral to the cavernous sinus, and here the trigeminal (gasserian or semillunar) ganglion is formed and gives off the three major branches.

Chapter 5: Facial sensations & movements On this page. Chapter 5: Facial sensations & movements. In this chapter, the functions of the trigeminal (CN V) and facial (CN VII) nerves will be discussed. Symptoms of damage to the trigeminal system are mainly loss of sensation in the face, although the mandibular division of the trigeminal nerve also controls jaw motion.

Trigeminal Neuralgia Causes. The pain associated with trigeminal neuralgia represents an irritation of the nerve. The cause of the pain usually is due to contact between a healthy artery or vein and the trigeminal nerve at the base of the brain. This places pressure on the nerve as it enters the brain and causes the nerve to misfire.rigeminal neuralgia, also known as tic douloureux, sometimes is described as the most excruciating pain known to humanity. The pain typically involves the lower face and jaw, although sometimes it affects the area around the nose and above the eye.

What is TN? Trigeminal neuralgia (TN), also called tic douloureux, is a chronic pain condition that affects the trigeminal or 5th cranial nerve, one of the most widely distributed nerves in the head.N is associated with a variety of conditions. TN can be caused by a blood vessel pressing on the trigeminal nerve as it exits the brain stem. This compression causes the wearing away or damage to the protective coating around the nerve (the myelin sheath).
