Cloumns Of Cranial Nerve Nuclei Flashcards
Mention components of GSE
They supply muscles derived from myotomes
Nuclei of III, IV, VI, XII
Mention nuclei of SVE
- Motor nucleus of V
- Motor nucleus of VII
- Nucleus ambiguus
They supply muscles derived from pharyngeal arches
Mention components of GVE
- Edinger Wesphal nucleus
- Supeior & inferior salivatory nuclei
- Dorsal motor nucleus of vagus
Nucleus solitaries forms to….&….columns
GVA & SVA
Mention component of GSA column
- Main sensory nucleus
- Spinal nucleus of trigeminal
- Mesencephalic nucleus
Mention components of SSA column
Cochlear & vestibular nuclei
Nucleus solitarius recieves fibers of IC carrying taste from…..
Posterior 1/3 of tongue
Circumvallate papillae
Describe path of inferior salivatory nucleus fibers
Tympanic branch of IX to tympanic plexus to lesser petrosal nerve to relay in otic ganglion and give postganglionic parasym fibers to parotid gland via auriculotemporal nerve.
The facial nerve supplies mucles derived from……while trigeminal supplies muscles derived from……
2nd pahryngeal arch
1st pharyngeal arch
Describe path of fibers from superior salivatory nucleus
Chorda tympani branch of facial nerve relay in submandibular ganglion give postganglion parasym fibers to submandibular & sulingual glands
Upper part of nucleus solitarius recieves taste fibers carried by…… from ant 2/3 of tongue & the…..from soft palate.
Chorda tympani
Greater petrosal nerve
Mention muscles supplied by trigeminal
4 muscles of mastication
Tensor palati, tensory tympani, anterior belly of digastric & mylohyoid
Describe path of Edinger-Westphal nucleus fibers
Fibers pass with oculomotor nerve to its inferior division to nerve to inferior oblique muscle then leave the nerve to relay in ciliary ganglion then give postganglionic parasymp fibers to ciliary muscles & sphincter pupillae muscle.
Nucleus solitarius gives CN……..
VII, IX, X
Spinal nucleus of V gives fibers to CN……
V, VII, IX, X
