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 is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
The condition was first described in 1909 by Danish ophthalmologist Christian Frederick Heerfordt, for whom the syndrome is now named. [6] It was originally attributed to mumps, but after further studies by Swedish doctor Jan G. Waldenström in 1937, it was classified as a distinct manifestation of sarcoidosis.
A neuronopathy affects the cell body of a nerve cell in the peripheral nervous system. [5] Amyotrophic lateral sclerosis; Spinal muscular atrophy; Spinal muscular atrophy with respiratory distress type 1; Atypical motor neuron diseases; Dorsal root ganglion disorders
The Heerfordt-Waldenstrom syndrome consists of sarcoidosis with parotid enlargement, fever, anterior uveitis, and facial nerve palsy. [2] IgG4-related sialadenitis: This term refers to IgG4-related disease (IgG4-RD) involving any of the major salivary glands, i.e. parotid or submandibular glands. This is often symmetrical and is usually ...
Receives taste from the posterior 1/3 of the tongue, provides secretomotor innervation to the parotid gland, and provides motor innervation to the stylopharyngeus. Some sensation is also relayed to the brain from the palatine tonsils. This nerve is involved together with the vagus nerve in the gag reflex. X Vagus: Both sensory and motor
Bilateral facial nerve paralysis may occur in Guillain–Barré syndrome, an autoimmune condition of the peripheral nervous system. [6] Moebius syndrome is a bilateral facial paralysis resulting from the underdevelopment of the VII cranial nerve (facial nerve), which is present at birth. The VI cranial nerve, which controls lateral eye movement ...
These include facial nerve weakness, rapid increase of the size of the lump as well as ulceration of the mucosa of the skin. [13] Mucoepidermoid carcinoma is a common malignant tumour of the salivary glands and has a low incidence of 4–13%. [13] Adenoid cystic carcinoma is also a common malignant salivary gland lesion and has an incidence of ...
