A

part of the orbits, lateral walls and floor of the nasal cavity and hard palate

32
Q

What bone contains the largest of paranasal sinuses ?

33
Q

What does the maxillae contain

A

largest of paranasal sinuses, infraorbital foramen, upper teeth, maxillary sinuses

34

A

to hold firmly the bones of the skull together

38
Q

What type of joints are sutures

A

fibrous joints

39
Q

What are the main sutures of the skull

A

squamous, lamboid, sagittal, coronal

40
Q

What do the squamous sutures unite?

A

unites the parietal bone with temporal bone

41
Q

What do the lamboid sutures unite?

A

unites parietal bones with the occipital bone

42

44
Q

What is a sinus?

A

cavity filled with air in skeleton of the head

45
Q

What are paranasal sinuses?

A

cavities around the nasal cavity within bones of the skull that are lined with extensions of the nasal mucous membrane

46
Q

Where do the paranasal sinuses open to?

A

all open into the nasal cavity

47
Q

What are the paranasal sinuses?

A

frontal, maxillary, sphenoidal, ethmoidal

48
Q

What is the purpose of the paranasal sinuses?

A
  • lighten the weight of the skull reducing muscle effort to keep it erect against gravity
  • contribute to the preparation of air for lungs by warming, cleaning, and moisturizing inhaled air
  • serve as resonating chambers for the sounds we speak/sing
49

A

suspended by ligaments and muscles

54
Q

What is the purpose of the hyoid bone

A

genetics
arthritis
jaw injury
