Question 1

ARISES FROM

Answer 1

Answer 2

the foramen ovale into the infratemporal fossa

Question 3

branches are

Answer 3

A,URICOTEMPORAL nerve
inferior alveolar nerve
lingual nerve
buccal nerve

Question 4

auricotemporal nerve

Answer 4

1. sends articular/sensory fibers to the TMJ

2. conveys postsynaptic secretomotor fibers from otic ganglion to the parotid gland

Question 5

inferior alveolar nerve

Answer 5

1. enters the mandibular foramen
2. forms dental plexus
3. mental nerve passes through mental foramen and supply the skin and mucous membrane of the lower lip, skin of the chin and the mandibular incisor teeth
