Exam 3 Flashcards
Name the branch of the maxillary artery that branches of off the “second part” (as demarcated by the lateral pterygoid muscle). What group of muscles does this supply?
Buccal Artery
supplies the muscles of mastication
Name the branch of the maxillary artery that branches of off the “Third part” (as demarcated by the lateral pterygoid muscle). what does this supply?
Posterior superior alveolar
Supplies upper molars and premolars
Name the branch of the maxillary artery that branches of off the “First part” (as demarcated by the lateral pterygoid muscle). State the path of this artery and the artery it becomes.
Inferior Alveolar
Enters the mandibular foramen where it supplies the lower teeth and gums
THEN passes through the mental foramen and becomes the mental artery
State the cranial foramen that the Middle meningeal artery and the Accessory meningeal artery respectively pass through.
Middle Meningeal Artery: passed through the foramen spinosum (along with the Meningeal branch of the trigeminal nerve)
Accessory Meningeal Artery: passes through the foramen ovale (along with the mandibular branch of the trigeminal nerve)
Compare the 2 branches of the maxillary artery that supply either side of the eardrum surfaces.
The Deep Auricular artery (lies within the parotid gland) supplies the outer surface of the eardrum
The Anterior Tympanic artery supplies the inner surface of the eardrum
What ganglion is described by the following?
Fused inferior cervical ganglion and T1 ganglion
Stellate ganglion
which of the 4 infrahyoid muscles is not innervated by the ansa cervicalis? what nerve innervates this muscle?
The Thyrohyoid muscle, which is innervated by the Hypoglossal nerve
State the 3 structures that pass through the gap between the skull and the superior constrictor muscle
Levator Palatini muscle
Auditory tube
Ascending Palatine Artery
State the 3 structures that pass through the gap between the Superior and Middle pharyngeal constrictor muscles
Stylopharyngeus muscle
Glossopharyngeal nerve
Stylohyoid muscle
State the 3 structures that pass through the gap between the Middle and Inferior pharyngeal constrictor muscles
Internal Laryngeal nerve
Superior Laryngeal Artery
Superior Laryngeal Vein
State the 2 structures that pass just inferior to the Inferior Pharyngeal Constrictor muscle
Recurrent laryngeal nerve
Inferior laryngeal artery
What type of lesion (and on what structure) is associated with the following? occlusion of what artery spares the reticular formation and leaves the pt is this condition?
Consciousness but quadriplegic
Bilateral lesions of the ventral pons
occlusion of the basilar artery
If a pt has bilateral lesions of the ventral pons and is quadriplegic, what neural structure can allow them to communicate via eye movements IF it is still intact?
The Corticobulbar fibers to the oculomotor nuclei
