-Skin
-Dense connective tissue
-Aponeurosis
-Loose connective tissue
-Periosteum
In which layer of scalp do vessels travel
Dense CT

-Palatopharyngeus - CN X
-Salpingopharyngeus - CN X
Identify nerves which form pharyngeal plexus
- On middle constrictor - pharyngeal branches of CN IX and X and sympathetic branches from superior cervical ganglion.
Vagal - all muscles except stylopharyngeus (CN IX)
Glands of pharynx are innervated by _
CN VII - greater petrosal nerve
Major arteries supplying pharyngeal wall
-Ascending pharyngeal
-Superior thyroid
Identify muscle that when contracts opens auditory pharyngeal tube
Tensor veli palatini
What is torus tubaris
Elevation of mucosa made by cartilaginous portion of auditory tube
What structures exit beneath torus tubaris
