Jugular foramen
What nerve is found in the submandibular triangle? Where does it pass in relationship to vessels?

IX, X, XI, XII
What originates from the styloid process superiorly and then passes between the superior and middle constrictors?
Stylopharyngeus
What is found superior to the opening of the auditory tube?

Superior laryngeal nerve
What is a superior continuation of the posterior longitudinal ligament? What is superior to this?
Tectorial membrane
The foramen magnum
What muscle attaches at an oblique line to the thyroid cartilage and the lateral surface of the cricoid cartilage?
What are the lowest set of inferior constrictor fibers that attach horizontally to the cricoid cartilage?
Inferior pharyngeal constrictor
Cricopharyngeus
Which constrictor has anterior attachments to the greater and lesser horns of the hyoid bone and the stylohyoid ligament?
Middle pharyngeal- the upper fibers of the inferior constrictor overlay the lower portion of the middle constrictor
What is a pear-shaped recess, bounded by the larynx (medially), thyroid cartilage (laterally) and the inferior constrictor (posteriorly)?
Piriform recess- REMEMBER- medial is the larynx, lateral is the thyroid cartilage, and posterior is the inferior constrictor
What is deep to the cruciform ligament and lateral to the superior longitudinal ligament?
Alar ligaments
What does the hypoglossal nerve pass through? ;)
Hypoglossal canal
What 2 things are found on the anterior surface of the cervical vertebral column?
Sympathetic trunk and the superior cervical sympathetic ganglion
What nerve is found posterolateral to the stylopharyngeus?
Glossopharyngeal nerve (CN IX)
What is the main dividing line between the oral cavity and the oropharynx, from soft palate to the tongue?
Palatoglossal fold
What constrictor has a superior attachment to the pharyngeal tubercle and anterior attachment to the pterygomandibular raphe?
Possible test question??
Superior pharyngeal constrictor- this is covered posteriorly by both he middle and inferior constrictor muscles
Found at the superior border of the superior pharyngeal constrictor you will find _________, the dense connective tissue that fills in the gap below the base of the skull and this constrictor.
Pharyngobasilar fascia
What is found within the oropharynx?
Palatoglossal fold (arch) Palatopharyngeal fold (arch) Palatine tonsil
Where is the pharyngeal nerve plexus found?
Posterolateral aspect of the pharynx
Where does the vertebral artery enter and exit?
The transverse foramen of C6 and the transverse foramen of C1
What is the opening into the larynx?
Inlet of the larynx (aditus)
What is posterior and superior to the torus tubarius?
Pharyngeal recess
What is found on the lateral wall of the nasopharnyx?
Opening of the pharyngotympanic tube Torus tubarius Salpingopharyngeal fold Pharyngeal recess Pharyngeal tonsil (adenoid)
The cruciate (cruciform) ligament of the atlas has 3 parts, what are they?
Superior longitudinal ligament (band)
Inferior longitudinal ligament (band)
Transverse ligament of the atlas
What is the posterior nasal apertures which are separated by the nasal septum?
Choana
Cleaning what fascia away from the posterior aspect of the cervical viscera reveals the musculature of what?
Buccopharyngeal
Posterior pharyngeal wall
What are the contents of the laryngopharynx?
Epiglottis
Inlet of the larynx (aditus)
Piriform recess
What are the contents of the carotid sheath? (Seen from the posterior view)
Where are these in relationship to one another?
ICA
IJV
Vagus nerve (CN X)
The IJV is lateral to the ICA, the vagus is in between (Vagus sandwich ;) )
The brain system, vertebral arteries, and cervical roots of the accessory nerves pass through what?
