What is this labelled here

A

Maxillary labial frenum

33
Q

How is sulci created

A

Mucosa lining the cheeks and lips arches over to form the roof and floor of the vestibule before reflecting onto the gingivae

34
Q

Label this

A

Deep lingual vein

35
Q

39
Q

What separates the posterior 1/3rds of the tongue from the anterior 2/3rds of the tongue

A

The sulcus terminalis

40
Q

What is the palate made up of

A

2 parts, the larger anterior hard palate and the posterior soft palate

The anterior hard palate is the maxilla

The posterior hard palate is the palatine bone

41
Q

How is the 4 bones of the palate joined by

A

Sutures

42
Q

How does cleft palate/lip occur?

A

Right and left halves of the palate begin life in embryo as separate structures. They migrate towards each other and fuse in midline. If this goes wrong cleft is caused
