Term
______ is called voice box. At this level of speech production, there is no phonemic discrimination yet.
Definition
Larynx
Term
The process of bringing two or more moveable speech structures together to form the sounds of speech.
Definition
Articulation
Term
Immobile articulators
Definition
Term
Complete velopharyngeal closure is required for the production of oral sounds since it will prevent air leakage to nasopharyngeal space and nasal cavity. A muscle that contributes to velopharyngeal closure through elevating the velum is:
Definition
Levator veli palatini
Term
The following are facial bones except for:
Definition

1. maxilla bone

2. lacrimal bone

3. palatine bone

4. zygomatic bone

5. parietal bone

Term
A single bone forming the anterior and posterior part of the medial nasal cavities.
Definition
Vomer
Term
Important for chewing
Definition
Buccinators
Term
The primary muscle of the lips
Definition
Orbicularis oris
Term
The laryngealpharynx and the oropharynx change resonance characteristics of each phoneme. The nasopharynx adds noticeable resonance to which sounds?
Definition
/m,n, ng/
Term
____ is an important structure because it contains the lower teeth and major extrinsic tongue muscles which are crucial for correct production of consonantal phonemes. This is also a major bone for mastication.
Definition
Mandible
Term
____ forms the floor of the nose and the nasal cavity. It is also a major bone of the roof of the mouth.
Definition
Palatine process of the maxilla
Term
All of the following bones form a part of the eye socket except for:
Definition

1. Zygomatic bone

2. Frontal bone

3. Ethomoid bone

4. Sphenoid bone

5. Lacrimal bone

Term
Facial expressions are important for
Definition
efficient verbal communication
Term
In humans, the tooth-bearing bones are ____ and the ______.
Definition

1. Maxilla

2.Mandible

Term
Retrognatic jaw corresponds to (mal) occlusion of:
Definition
Type II
Term
Prognatic jaw corresponds to (mal) occlusion of:

Type III
Term

An adult has 34 permanent teeth.

Definition
False
Term

True or False

 

An adult has 18 permanent molars.

Definition
False
Term
For alveolar stop sounds, the tip of the tongue should be blocked by
Definition
upper incisors
Term

True or False

 

We have two alveolar processes by which tooth roots are supported.

Definition
True
Term

True or False

 

The movements of the tongue, necessary for rapid articulation of phonemes, require very delicate control of the related muscles.

Definition
True
Term
Superior longitudinal muscle:
Definition
shorten the tongue and raise the tip of the tongue.
Term
Velopharyngeal insufficiency causes
Definition
hypernasality
Term
Flattens tongue
Definition
Vertical muscle
Term
All of the following are extrinsic tongue muscles except for:
Definition

1. Genioglossus

2. Hyoglossus

3. Superior longitudinal muscle

4. Styloglossus

5. Palatoglassus

Term
Posterior portion of genioglossus muscle:
Definition
Protrudes the tongue
Term
Palatoglossus muscles:
Definition
Depress the velum and elevates the tongue
Term
Levator veli palatine:
Definition
Originate from the temporal bone
Term
Hyoglossus muscle:
Definition
Pulls the tongue backwards
Term
The structure at the inferior portion of the tongue that connects the tongue with the lower jaw (mandible) is called:
Definition
Lingual frenum
Term
_______ is the most superficial of the mastication muscles. It is a massive and very strong muscle that is efficient for chewing. 
Definition
Masseter
Term
All of the following muscles are used for depressing the mandible except for:
Definition

1. Digastric muscles

2. Stylohyoid muscles

3. Mylohyoid muscles

4. Geniohyoid muscles

Term
When a person is producing voiced and voiceless sounds 'th' sounds as in 'think' or 'they', the muscle that is most involved is the:
Definition
Genioglossus
Term
When a person is adducting and abducting the vocal fold, which muscles are most involved with that process?
Definition

1. Thyroaryteniods

2. LCA (lateral cricoaryteniod)

3. Transverse aryteniods

Term
Styloglossus muscle is important for the articulation of:

1. Levator anguli oris

2. Buccinators

3. Rizorius

4. Levator Labii Superios

5. None of the above
