Study Notes
Branches of the Artery
- Zygomatic branch
- Buccal branch
- Mandibular branch
- Cervical branch
Origin and Intrapontine Course
- Has 6 nuclei of origin:
- 1 motor nucleus
- 2 sensory nuclei
- 3 parasympathetic nuclei
- Located in the lower part of the pons
- Runs a sinuous course to accommodate the mobility of surrounding structures
- Can be palpated against the mandible, at the antero-inferior border of the masseter muscle
Composition and Ganglia
- Mixed sensory and parasympathetic composition
- Immediately outside the jugular foramen, lies two ganglia (collections of nerve cell bodies)
Nerve Connections
- Gives rise to the carotid sinus nerve, which enters the pharynx by passing between the superior and middle pharyngeal constrictors
Venous Connections
- Communicates with the cavernous sinus via emissary veins
- Communicates with the facial vein via the deep facial vein
