The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue.
This nerve is involved (together with nerve IX) in the pharyngeal reflex or gag reflex. XI Accessory. Sometimes: cranial accessory, spinal accessory. Mainly motor Cranial and Spinal Roots Located in the jugular foramen. Controls the sternocleidomastoid and trapezius muscles, and overlaps with functions of the vagus nerve (CN X). Symptoms of ...
Nerves may be compressed because of increased intracranial pressure, a mass effect of an intracerebral haemorrhage, or tumour that presses against the nerves and interferes with the transmission of impulses along the nerve. [22] Loss of function of a cranial nerve may sometimes be the first symptom of an intracranial or skull base cancer. [23]
The cervical branch of the facial nerve is a branch of the facial nerve (VII). It runs forward beneath the platysma muscle, and forms a series of arches across the side of the neck over the suprahyoid region. One branch descends to join the cervical cutaneous nerve from the cervical plexus.
The intermediate nerve, nervus intermedius, nerve of Wrisberg or glossopalatine nerve [1] [2] [3] is the part of the facial nerve (cranial nerve VII) located between the motor component of the facial nerve and the vestibulocochlear nerve (cranial nerve VIII). It contains the sensory and parasympathetic fibers of the facial nerve.
An injury to this nerve during a surgical procedure can distort the expression of the smile as well as other facial expressions. The marginal mandibular branch of the facial nerve is found superficial to the facial artery and (anterior) facial vein.
Pontine cranial nerve nuclei. Chief or pontine nucleus of the trigeminal nerve sensory nucleus (V) Motor nucleus for the trigeminal nerve (V) Abducens nucleus (VI) Facial nerve nucleus (VII) Vestibulocochlear nuclei (vestibular nuclei and cochlear nuclei) (VIII) Superior salivatory nucleus; Pontine tegmentum.

The pontine tegmentum contains nuclei of the cranial nerves (trigeminal (5th), abducens (6th), facial (7th), and vestibulocochlear (8th) and their associated fibre tracts. . The dorsal pons also contains the reticulotegmental nucleus, the mesopontine cholinergic system comprising the pedunculopontine nucleus and the laterodorsal tegmental nucle
