25
Define Adenoid Pad
The Posterior wall of the Nasopharynx it is characterized by an aggregate of lymphatic tissue known as pharyngeal tonsil (adenoids)
26
Nasal Cavity
Consist of the following: Nasal Septum Conchae or Turbinates Nasal tip Columella Nares(naris)
27
Define the Nasal Septum
Separates the Nasal Cavity into two symmetrical chambers
28
Describe Conchae or Turbinates
These are the lateral walls of the nasal cavitities that are composed of superior, middle and inferior nasal (shell) to include their corresponding nasal passages (meatus, meati)
29
Where is the Nasal Tip located
At the very tip of the Nose. Also known as the Apex
30
What is the Columella
The Columella is the continuous portion of the Philtrum of the nasal septum.
31
What distinction does the Philtrum give the Nose
It is the vertical groove that connects the septum to the Nose.
32
How do You describe Nares?
It is the base of the nose that includes the nostrils (nares)
33
How is the Posterior Conchae different from the Inferior Conchae of the nose?
Also known a the posterior nares allows the nostrils and the pharynx to communicate within the nasal cavity
34
Name the Oral Cavity Articulators
Tongue Tongue Muscles Intrinsic Tongue Muscles Extrinsic Innervation Teeth Lips Hard Palate Faucial Pillars Tonsils Buccal Cavity
35
What is the oral cavity bounded how?
Anteriorly and laterally by the teeth, and the alveolar process, superiorly by the hard and soft palates, posteriorly by the palatoglossal arch and inferiorly by the muscular floor primarily the tongue
36
The Lips
Are composed of four layers of tissue, which are cutaneous, muscular, glandular, and mucous
37
The Hard Palate
Articulates at the mid-line and contribute to about the anterior 3/4ths of the bony roof of the mouth and floor of the nasal cavity.
38
The Rugae
Are transverse ridges or wrinkles that are mucous membranes that develop on the posterior slope of the alveolar arch.
39
The Raphe are
Presents mid-line and is Posterior to the rugae and continued back throughout the length of the palate.
40
Palatal Vault or arch is
The physiology of the hard palate, from thick at the anterior and lateral margins, becoming progressively thinner toward the midline
41
Faucial Pillars are
Anterior and Posterior It is the the mouth cavity has been transversely slit at the cheeks and the tongue is pulled backward. it is notice between the uvlula
42
The Tonsils are
A small triangular space that is wider below than above the arches of the Fauces, which are between the palatoglossal and the palatopharyngeal arches.
43
Buccal Cavity is
The small limited space that is by the lips and cheeks externally and by the gums and teeth internally. When jaw is closed it is the small space on either side behind the molars or wisdom teeth.
44
What ring consists of the palatine tonsils laterally, the adenoids superiorly, and the lingual tonsil inferiorly.
Waldeyer's Ring
45
The Tongue is considered to be
The most important and the most active of articulators
46
The Divisions of the Tongue are?
Front Blade Tip Back
47
The Dorsum of the tongue has division as well. What are they?
Foramen Cecum- is a remanant of the embryonic origin of the thyroid gland. Sulcus terminalis- a shallow V-Shaped groove that courses anteriorly and laterally to the margins of the tongue. Longitudinal Sulcus- it continues from front to back to a pit of variable extent.(foramen cecum)
48
What are the INTRINSIC MUSCLE of the TONGUE
Superior Longitudinal Inferior Longitudinal Transverse Vertical
49
The muscle of the tongue that is a thin layer of oblique and longitudinal muscle fibers, lying deep of the membrane of the dorsum of the tongue is called
Superior Longitudinal Muscle
50
What physical effects does the Inferior Longitudinal muscle of the tongue have.
Upon contractions this muscle either shortens the tongue or pulls the tip downward.
51
True or False? The contraction of the transverse muscle causes the tongue to narrow and to become elongated.
True
52
Besides being confined to the lateral portion of the tongue. What else does the Vertical Muscle of the tongue do?
It flattens the Tongue
53
The Extrinsic Muscle of the Tongue are?
Genioglossus- which forms the bulk of the Tongue tissue. Styloglossus- the smallest of the three muscle that arise at the styloid processes. Palatoglossus- may be regarded as a muscle of the tongue or of the palate. Hyoglossus Muscle- a thin quadrilateral sheet muscle, It originates from the upper border of the greater cornu and from the corpus of the hyoid bones.
54
What are the Innverator's of the Tongue?
CN XII, CN VII, and CN V
55
What is the Teeth considered to a precursor to?
The Digestive Process.
56
The Teeth are connected to what features?
Alveolar Ridge, Surfaces, and Deciduous
57

What are the dental Surfaces
Buccal Surface -----Lingual Surface left side Labial surface--------Lingual Surface left side to the front teeth, Mesial Surface---------Distal Surface middle front to the right side. Distal-Occlusal-Distal Surface-------Mesial Surface right side to back right.
59
What is the formula for Deciduous Dental Arch?
I 2/2 C 1/1 M 2/2 X 2= 20
60
What are the names of the the Primary Dental Arch?
I= incisor C= canine M= molar
