Infratentorial Vascular Anatomy
Of note, the degree of variability in the anatomy of the posterior circulation (point of origin of different arteries, the size of the PICA-AICA complex, degree of asymmetry, etc.) often…
Cranial Nerve XI: Spinal Accessory
Fig. 22.2 Axial thin CISS MRI image at the level of the medulla shows the cranial root of CN11 (arrows) emerging from the post-olivary sulcus just inferior to CN10. The cranial…
Cranial Nerve XII: Hypoglossal
23.2 Function The hypoglossal nerve has only GSE motor fibers. It innervates the intrinsic and all of the extrinsic tongue muscles except the palatoglossus (which is innervated by CN X)….
Cranial Nerve X: Vagus
21.2 Function Special visceral motor function (SVE): from nucleus ambiguus to all intrinsic muscles of the larynx, all pharyngeal and soft palate muscles except for stylopharyngeal muscle (CN IX) and…
Cranial Nerve IX: Glossopharyngeal
20.2 Function Branchial motor function (SVE): The muscular branch from the nucleus ambiguus innervates the stylopharyngeal muscle to elevate the pharynx during phases of swallowing and speech. It also innervates…
Cranial Nerve VI: Abducens
17.2 Function The abducens nerve has only GSE motor fibers. It innervates the lateral rectus muscle, the activation of which causes abduction of the eye allowing for conjugate horizontal gaze….
