Q

What is the foramen which lies in the midline just behind the incisor teeth called?

A

The incisive foramen

30
Q

What nerve passes through the incisive foramen?

A

The nasopalatine nerve

31
Q

What does the nasopalatine nerve supply?

A

The anterior part of the mucosa of the hard palate

32
Q

Describe the nasopalatine nerve

A

Iy is branch of the maxillary nerve which travels though the nasal cavity before emerging into the hard palate

33
Q

What makes up the posterior part of the hard palate?

A

The right and left palatine bones

34
Q

What is foramen lying more posteriorly on the hard palate called?

A

The greater palatine foramina

35
Q

What do the greater palatine foramina transmit?

A

The greater palatine nerves

36
Q

What do The greater palatine nerves supply?

A

The mucosa over the hard palate

37
Q

What supples the soft palate?

A

The lesser palatine nerves

38
Q

What are the greater and the lesser palatine nerves branches of?

A

The maxillary nerve

39
Q

What is the foramen found on the anterior aspect of the maxilla called?

A

The infraorbital foramen

40
Q

What does the infraorbital foramen transmit?

A

The infraorbital nerve

41
Q

Describe the infraorbital nerve

A

It forms when the maxillary nerve becomes once it starts to travel under the eye.

42
Q

What do the branches of the infraorbital nerve supply?

A

Supply sensation to a large area on the front of the face, including parts of the cheek, the side of the nose and the upper lip.

43
Q

If you could follow the infraorbital nerve back through its foramen what would you find?

A

That it lies in a canal called the infraorbital canal

44
Q

What is the difference between a canal and a groove?

A

A groove doesn’t have a roof

45
Q

More posterior to the infraorbital canal where does the infraorbital nerve lie?

A

In a groove

46
Q

What branch does the infraorbital nerve give off when its in the canal an groove?

A

Anteriorly there are the anterior superior alveolar nerves

47
Q

What do the the anterior superior alveolar nerves supply?

A

The anterior teeth

48
Q

What does the maxilla contain?

A

A large maxillary sinus

49
Q

Where does the anterior super alveolar nerve travel??

A

Travels immediately under the mucosa lining this maxillary sinus

50
Q

Where do the the middle superior alveolar nerves arise from?

A

The infraorbital nerve more posteriorly that the anterior superior nerves

51
Q

Does everyone have a middle superior alveolar nerve?

A

No it is absent in a sizeable proportion of the population

52
Q

If you were to follow the infraorbital nerve even more posteriorly past the infraorbital groove what would you find?

A

a space lying immediately posterior to the maxilla called the pterygopalatine fossa

53
Q

What happens at the pterygopalatine fossa?

A

The maxillary nerve gives off the posterior superior alveolar nerves

54
Q

When does the maxillary nerve become the infraorbital nerve?

A

When it passes into the infraorbital groove

55
Q

Where do the posterior superior alveolar nerves run?

A
  1. Down the posterior surface of the maxilla
  2. Through the posterior superior alveolar canal
  3. Then under the mucosa of the maxillary sinus before reaching the teeth
56
Q

Where is the mandibular foramen found?

A

On the medial surface of the ramus

57
Q

What is the lingula?

A

A small projection of bone that partially covers the mandibular foramen

58
Q

What does the sphenomandibular ligament attach to?

A

The lingula

59
Q

Where is the mylohyoid groove found?

A

the groove that begins at the inferior margin of the mandibular foramen

60
Q

Where is the prominent mylohyoid line found?

A

Superior to the mylohyoid groove

61
Q

Where is the mental foramen found?

A

on the external surface of the mandible It lies approximately between the apices of the two premolar teeth

62
Q

Where is the incisive foramen found?

A

The midline just behind the incisor teeth

63
Q

What supplies the anterior part of the mucosa of the hard palate?

A

The nasopalatine nerve

64
Q

What do the right and left palatine bones make up?

A

The posterior part of the hard palate

65
Q

Where are the greater palatine foramina found?

A

Found posteriorly on the hard palate

66
Q

What supplies the mucosa over the hard palate?

A

The greater palatine nerves

67
Q

The lesser palatine nerves supply what?

A

The soft palate

68
Q

What Supplies sensation to a large area on the front of the face, including parts of the cheek, the side of the nose and the upper lip?

A

The infraorbital nerve

69
Q

What lies in the infraorbital canal?

A

The infraorbital nerve before it goes through the infraorbital foramen

70
Q

What supplies anterior teeth?

A

The anterior superior alveolar nerves
