Feb 15, 2024 · The facial nerve is the seventh (CN VII) cranial nerve and comprises two roots, a motor root and a smaller mixed sensory, taste and parasympathetic root, known as nervus intermedius, which join together within the temporal bone (TA: nervus facialis or nervus cranialis VII). The facial nerve has a complex and broad range of functions.
Apr 11, 2019 · An overview of the anatomy of the facial nerve (CN VII) including its course, the facial nucleus, branches of the facial nerve and facial nerve palsy.
Anatomical course of the facial nerve: (will be discussed later in more detail) Intracranial part : The nerve arises in the pons (cerebellopontine angle)
The facial nerve (Cranial Nerve VII) is one of the most important and continuously used nerves in the body, connecting at least 21 muscles with the brain, providing motor innervation to the muscles of facial expression which are also involved in mastication, speech and the expression of our emotions.

3 days ago · The facial nerve, or cranial nerve (CN) VII, is the nerve responsible for facial expression. The pathways of the facial nerve are variable, and knowledge of the key intratemporal and...
Course. The facial nerve courses laterally to enter the facial canal of the temporal bone via the internal acoustic meatus. Once inside and embedded in the petrous temporal bone, it passes inferiorly in the facial canal, just posterior to the tympanic cavity, where it gives off several branches.
Facial nerve course and branches. On its course, the facial nerve gives off many motor, sensory, and parasympathetic branches. The anatomical course of this nerve is quite complex, and it may be divided into two parts: intracranial and extracranial.
Nov 8, 2024 · Introduction. The facial nerve displays a lot of variations and anomalies in its course as it traverses the temporal bone from the internal acoustic meatus to the stylomastoid foramen .It is divided into three parts: labyrinthine, tympanic, and mastoid segments, among which the mastoid segment of the facial nerve is highly prone to injury during its exploration .The mastoid segment (13-15 mm) extends from the second genu to the stylomastoid foramen and assumes a vertical position as it drops ...
Oct 31, 2024 · The facial nerve detects sensation from the small area behind the ear described as the auricle. The sensory information from this area is transmitted through the facial nerve to the brainstem, then to the thalamus in the brain, and eventually to the cerebral cortex, where the brain can integrate and make sense of the sensation.
