O: Soft palate
I: Blends w/wall of pharynx
N: Vagus nerve CN X
Sensory Innervation of pharynx
Mucus membrane by glossopharyngeal nerve, lower portion of wall via internal laryngeal branch of vagus
Blood supply to the pharynx
Ascending pharyngeal artery
Maxillary artery branches
Facial artery branches
Contributions to the pharyngeal plexus
1) Vagus- motor (pharyngeal branches)
2) Glossopharyngeal nerve- sensor innervation, motor to stylopharyngeus from mucus membrane
3) Maxillary division of Trigeminal - sensory to nasopharynx
4) Sympathetic fibers (derived from SCG), Act on BV of pharyx
5) Parasympathetic - CN7 and Vagus to mucus glands of mucus membrane
Origin and path of Spinal accessory nerve (spinal levels)
C1-C4 Ascend through foramen magnum, join vagus briefly in cranial vault, leave through jugular foramen and head to SCM and trapezius
Articular surfaces involved in TMJ
Head of condylar process of mandible
Mandibular fossa of temporal bone
Articular tubercle of temporal bone
Postglenoid tubercle of temporal bone
Division of joint and actions of TMJ spaces
Superior joint (above articular disk)- gliding movement
Inferior joint space- Hinge movement
