Q

Which way does the squamous portion and the mastoid process of the temporal bones move during SBS extension?

A

Squamous portions move medially

Zygomatic processes and mastoid move laterally

17
Q

What clinical symptoms are associated with temporal bone dysfunction?

A

TMJ
Head Pain
Neck Pain (SCM attaches to mastoid)

Ear: Dizziness, ear infections, tinnitus

18
Q

Why is the frontal bone considered a paired bone?

A

In babies, the suture is still there and fuses as adults

19
Q

What bones does the frontal bone contact? (7)

A

Parietals
Sphenoid
Zygoma

Lacrimals
Ethmoid
Maxillae
Nasals

20
Q

How many axises does the frontal bone have?

A

2 vertical axises

21
Q

Describe the movement in the lateral portion of the frontal bone and the glabella during SBS flexion?

A

Lateral portions move anterior,
Glabella moves posterior
-kind of like if you were folding the frontal bone in half

22
Q

Describe the movement in the lateral portion of the frontal bone and the glabella during SBS extension?

A

Lateral portions move posterior
Glabella moves anterior

Prayer hands as you exhale

23
Q

What are the clinical symptoms of frontal bone issues?

A 
Frontal or global head pain
Frontalis muscle issues
Sinusitis
Visual issues
Anosmia (Cant Smell)
24
Q

What is a bicoronal synostosis?

A

Where both of the frontal bones fuse with the parietal bones at coronal suture, leaving space for the head to grow very wide

wide head=brachycephaly
Tall head=turricephaly

25
Q

What is a unicoronal synostosis?

What does it Create?

How is forehead?

A
  • Where one of the frontal bones fuses with the parietal bones at coronal suture, leaving space for the head to grow crooked
  • Creating a facial twist

Affected forehead is flat, while contra forehead is more anterior
