Flashcards in Dissection 8: Pharynx, Larynx, and Nasal Cavity Deck (35):
Mucosal folds extending from epiglottis to arytenoid cartilages and forming the borders of the laryngeal inlet.
Auditory tube opening
Located within the nasopharynx just under the torus tubarius.
Cervical sympathetic trunk
Slender, vertically coursing nerve lying medial to the vagus nerve having ganglion along its length, particularly the large superior cervical ganglion.
Common carotid artery
Medial to IJV.
Just inferior to the laryngeal inlet; its lamina forms a bulge that projects into the laryngopharynx forming the piriform recesses on each side.
Small, paired muscles on the external surface of the larynx spanning between cricoid cartilage and thyroid cartilage.
Paired concavities between the posterior one third of the tongue and the tip of the epiglottis.
Pear-shaped cartilage that occupies the anterior superior aspect of the larynx.
Small, midline depression in the tongue at the junction of its anterior two thirds and posterior one third.
Seen coursing somewhat vertically as it wraps around the stylopharyngeus muscle.
Seen descending from base of skull and coursing laterally and anteriorly around the external carotid artery at the origin of the occipital artery.
Area of the larynx below the true vocal folds.
Internal jugular vein
Lies lateral to the common carotid artery.
Area of the pharynx below the tip of the epiglottis and extending down to the level of the cricoid cartilage.
Levator veli palatini muscle
Vertically oriented muscle between the torus tubarius and the soft palate. It elevates the soft palate when swallowing and is innervated by the vagus nerve.
Located on the posterior one third of the tongue.
Two parallel muscles of the soft palate that extend to the uvula.
Upper area of the pharynx between the sphenoid sinus and the uvula.
Area of the pharynx between the soft palate and the tip of the epiglottis.
Two vertical gutters in the laryngopharynx that lie on either side of the cricoid lamina that bulges into the pharynx.
Posterior cricoarytenoid muscle
Muscle that spans between the lamina of the cricoid cartilage to the muscular processes of the arytenoid cartilages.
Small fold in the nasopharynx that extends from the torus to the soft palate. It overlies the levator veli palatini muscle.
A small fold in the nasopharynx that extends downward from the torus to the pharynx. It overlies the salpingopharyngeus
Small vertical muscle deep to the salpingopharyngeal fold. It is one of the elevators of the pharynx when swallowing.
Soft palate and uvula
Moveable structure attached to the posterior end of the hard palate; the uvula moves up and down to seal the oropharynx from the nasopharynx.
A paranasal sinus located in the body of the sphenoid bone. It is lined by mucosa and drains into the sphenoethmoidal recess.
A cylindrical muscle that is obliquely positioned lateral to the pharynx; it inserts into the pharyngeal wall by passing between
the superior and middle pharyngeal constrictor muscles. CN IX wraps around it.
Two, raised, mucosal folds on the floor of the mouth.
Superior cervical sympathetic ganglion
Large swelling at the upper end of the cervical sympathetic trunk.
Tensor veli palatini muscle
A vertically oriented muscle just anterior and lateral to the levator veli palatini. It tendon turns 900 around the hamulus of the medial pterygoid plate.
Vertically coursing nerve lying lateral to the cervical sympathetic trunk and between the common carotid artery and the IJV.
Ventricle of larynx
Small pocket or cul-de-sac that extends laterally between the true and false vocal folds.
Mucosal folds above the ventricle of the larynx. Also known as false folds.
Vestibule of larynx
Region of the inner larynx between the aryepiglottic folds and the true vocal folds. Also called supraglottic region.
