Many animals die early because of the hepatic insufficiency combined with the widespread tissue damage. December Learn how and when to remove this template message. The facial nerve also supplies preganglionic parasympathetic fibers to several head and neck ganglia. The facial motor nucleus receives a prominent 5-HT innervation, as demonstrated by fluorescence histochemistry Fuxe, and biochemical measures Palkovits et al. The clinical presentation would show the ipsilateral eye positioned out in primary position and only able to move in as far as the midline.
The facial nerve also supplies a small amount of afferent innervation to the oropharynx below the palatine tonsil. Nuclei nucleus ambiguus spinal accessory nucleus Cranial Spinal. Anatomical terms of neuroanatomy [ edit on Wikidata ]. Upper motor neurons of the cortex send axons that descend through the internal capsule and synapse on neurons in the facial motor nucleus. The posterior component, however, although now only receiving input from the right hemisphere, is still able to allow the temporal branch to sufficiently innervate the entire forehead.
This article does not cite any sources. Anatomy of the pons. Plan of the facial and intermediate nerves and their communication with other nerves. In other words, this means lower motor neurons of the facial nerve can leave either from the left anterior, left posterior, right anterior or right posterior facial motor nucleus. Branches of the facial nerve leaving the facial motor nucleus FMN for the muscles do so via both left and right posterior dorsal and anterior ventral routes. Near origin Intermediate nerve Geniculate. Trapezoid body Trigeminal lemniscus Dorsal trigeminal tract Ventral trigeminal tract Medial lemniscus Lateral lemniscus Medial longitudinal fasciculus Vestibulo-oculomotor fibers Anterior trigeminothalamic tract Central tegmental tract.
