Question 3

Auditory ear

Answer 3

Connects nasopharynx with tympanic cavity
Normally closed, lumen opens when tensor veli palatine contracts
Sensory via glossopharyngeal

Question 4

Middle ear: arterial supply

Answer 4

Anterior tympanic artery form first part of maxillary
Contributions form ascending pharyngeal, middle meningeal, posterior auricular, artery of pterygoid canal and caroticotympanic branch of internal carotid

Question 5

Chords tympani

Answer 5

Crosses medial surface of tympanic membrane and handle of the malleus
Leaves tympanic cavity via petrotympanic fissure
Joins lingual nerve

Question 6

External auditory meatus

Answer 6

2.5cm long

Mainly auriculo-temporal form CNV3 and auricular branches form facial nerve and vagus

Question 7

Tympanic membrane

Answer 7

8mm in diameter
Chorda tympani across medial surface
Malleus attached to inner surface, lateral; auriculotemporal nerve and auricular branch of vagus. Medial; tympanic branches of glossopharyngeal nerve

Question 8

Answer 8

Elastic cartilage
Muscle of facial expression but vestigial in humans
Lymph to parotid and cervical lymph nodes

Question 9

Divisions of the ear

Answer 9

External- auricle, external auditory meatus, external surface of tympanic membrane
Middle- internal surface of the tympanic membrane, tympanic cavity, ossicles, pharyngotympanic tube
