the incisors

4

Condyloid process

5

What is the very top of the mandible called?

Coronoid process

6

What is the genu of the mandible?

Where the L/R meet

7

Where do sensory nerves for teeth enter and leave?

Enter inferior alveolar foramen
exit mental foramen

8

What passes through infraorbital foramen?

Infraorbital nerve

9

What bones fuse to form the hard palate?

Palatine, maxilla, incisive

10

What makes up the primary and secondary palate?

Primary- lip and incisive bone
Secondary- hard and soft palate

11

What 3 bones make up the occipital bone?

supraccipital, exoccoiptal, basioccipital

12

Where does the spinal cord leave?

Foramen magnum

13

What articulates with C1?

Occipital condyles

14

What does the hyoid apparatus support?

Tongue and larynx

15

What causes a cleft lip and a cleft palate?

Cleft lip- failure to close primary palate
Cleft palate- failure to close secondary palate

16

What is syringomyelia?

Occipital bone is undersized and cerebellum presses against foramen magnum and interrupts flow of CSF
