Examples of "facial_nerve_cn"
A branch from the extracranial path of the
facial
nerve
(
CN
VII) innervates the Stylohyoid muscle.
The cranial nerves containing GVE fibers include the oculomotor nerve (CN III), the
facial
nerve
(
CN
VII), the glossopharyngeal nerve (CN IX) and the vagus nerve (CN X).
The chorda tympani (a branch of the
facial
nerve
,
CN
VII) joins it at an acute angle here, carrying taste fibers from the anterior two thirds of the tongue and parasympathetic fibers to the submandibular ganglion.
The metencephalon is the embryonic part of the hindbrain that differentiates into the pons and the cerebellum. It contains a portion of the fourth ventricle and the trigeminal nerve (CN V), abducens nerve (CN VI),
facial
nerve
(
CN
VII), and a portion of the vestibulocochlear nerve (CN VIII).
Like all muscles of facial expression, the risorius is innervated by the
facial
nerve
(
CN
VII). The specific branch is debated, with some sources giving marginal mandibular branch of the facial nerve and others giving buccal branch of the facial nerve.
The
facial
nerve
(
CN
VII) also has buccal branches, which carry motor innervation to the buccinator muscle, a muscle of facial expression. This follows from the trigeminal (V3) supplying all muscles of mastication and the facial (VII) supplying all muscles of facial expression.
The zygomatic nerve carries sensory fibers from the skin. It also carries post-synaptic parasympathetic fibers (originating in the pterygopalatine ganglion) to the lacrimal nerve via a communication. These fibers will eventually provide innervation to the lacrimal gland. These parasympathetic preganglionic fibers come from the
facial
nerve
(
CN
VII).
Larger tumors can press on the trigeminal nerve (CN V), causing facial numbness and tingling - constantly or intermittently. The
facial
nerve
(
CN
VII) is rarely affected in the same way; however, due to its proximity to some structures of the inner and middle ear, it can be damaged during radiological treatment or surgical removal of the tumor, particularly in the case of large growths.
Around 20% of parotid tumors are malignant, with the most common tumors being mucoepidermoid carcinoma and adenoid cystic carcinoma. Other malignant tumors of the parotid gland include acinic cell carcinoma, carcinoma expleomorphic adenoma, adenocarcinoma (arising from ductal epithelium of parotid gland), squamous cell carcinoma (arising from parenchyma of parotid gland), and undifferentiated carcinoma. Metastasis from other sites like phyllodes tumour of breast presenting as parotid swelling have also been described. Critically, the relationship of the tumor to the branches of the
facial
nerve
(
CN
VII) must be defined because resection may damage the nerves, resulting in paralysis of the muscles of facial expression.
The zygomaticus minor is a muscle of facial expression. It originates from malar bone and continues with orbicularis oculi on the lateral face of the levator labii superioris and then inserts into the outer part of the upper lip. Do not confuse this with the zygomaticus major, which insets into the angle of the mouth. It draws the upper lip backward, upward, and outward (used in making sad facial expressions). Like all muscles of facial expression, it is innervated by the
facial
nerve
(
CN
VII).
Since both the short and long ciliary nerves carry the afferent limb of the corneal blink reflex, one can test the integrity of the nasociliary nerve (and, ultimately, the trigeminal nerve) by examining this reflex in the patient. Normally both eyes should blink when either cornea (not the conjunctiva, which is supplied by the adjacent cutaneous nerves) is irritated. If neither eye blinks, then either the ipsilateral nasociliary nerve is damaged, or the
facial
nerve
(
CN
VII, which carries the efferent limb of this reflex) is bilaterally damaged. If only the contralateral eye blinks, then the ipsilateral facial nerve is damaged. If only the ipsilateral eye blinks, then the contralateral facial nerve is damaged.
