Nasal, Lacrimal, Maxillary, and Palatine Bones

There are 14 Facial bones:

• Two Nasal Bones

• Two Lacrimal Bones

• Two Maxillary Bones

• Two Palatine Bones

• Two Zygomatic Bones

• Two Inferior Nasal Conchae

• The Vomer

• The Mandible

The two nasal bones form the _

bony bridge of the nose

Posterior to the two nasal bones are the lacrimal bones, which are situated on the _

medial wall of each orbit

The junction of the lacrimal bones to the maxillary bones or maxillae is the _

lacrimal groove

The lacrimal groove accommodates the _

lacrimal sacs, the drainage route for excess lacrimal fluid (tears)

The two largest immovable bones are the _

maxillary bones

The maxillary bones fuse at the

midline to form a pointed process termed the anterior nasal spine

The maxillary bones contain the _

maxillary sinuses

The maxillary bones have four processes:

• The frontal process

• The alveolar process

• The zygomatic process

• The palatine process

The _ articulates with the frontal bone of the cranium

frontal process

The _ has several depressions and accepts the roots of the teeth

alveolar process

The _ communicate with the zygoma bones (cheekbones) of the face

zygomatic process

The _ extends posteriorly to form three-fourths of the hard palate

palatine process

The _ create the last quarter of the hard palate, and extend vertically to form part of the nasal cavity

palatine bones
