TOPIC 5

Question 1

1. N. Mylohyoideus

Answer 1

Nr 1. Easiest to find
Running ventrally on the mandible
Branches of the N. alveolaris inferior coming from the N.mandibularis (V3)

Question 2

2. N.Hypoglossus

Answer 2

Brachiocephalicus m, go under, behind omotransversarius and brachiocephalic.
Transect cleidocervicalis
A thick nerve
Motor nerve XII
Foramen: Foramen hypoglossus
Runs with A.lingualis: Divide into deep + superf as it enters the tounge
Innervates instrinsic and extrinsic toung muscles

Running between the level of the median raphe and the median margin of the mandible.

Question 3

N. Alveolaris inferior

Answer 3

Location: Passes inbetween the median and lateral pterygiod muscle
Branches of N.mandibularis (V3)
Gives of N. mylohyoideus (motor nerve)
Foramen: Foramen mandibularis - alveolar chanel - Exits foramina mentalia

Question 4

N. Lingualis

Answer 4

Branches of N.mandibularis (V3)
Leaves the mandibular nerve by stylohyoid bone
Crosses medialy on the mylohyoid muscle
Gives of: N.sublingualis
Devides into superf & deep branch in the tongue

Question 5

mm. Pterigoidei

Answer 5

Lateral:
O: Processus Pterigoidea of sphenoid bone
I: Medial surface of mandible and thr condylar process
A: Raises, pushes and draws the mandible forward

Medial:
O: Same as lateral + pterigoid bone and peripendicular plate
I: Medial surface of the mandible
A: Raises mandible

Question 6

N. mandibularis (V3)

Answer 6

Sensory and motor nerve
Foramen: Foramen Ovale
Gives of 2 branches before deviding intonits terminal branches
- N. Autuculotemporal nerve - Transverse facial
- N. Buccalis

Terminal branches

• N. alveolaris inferior -> N.Mylohyoideus - N.mentalia
• N. lingualis -> N.Sublingualis
