Ethmoid Bone

Term

 

 

 

What makes up the nasal septum?

Definition
Perpendicular plate of the ethmoid bone superiorly, vomer inferiorly, cartilaginous septum anteriorly.
Term

 

 

 

Where is the eustachian tube and what does it do?

Definition

 

 

 

The Eustachian Tube or, the Pharyngotympanic tube, goes from the middle ear to the narsopharynx and it drains the middle ear and equalizes pressure on both sides of the tempanic membrane to prevent the tempanic membran from rupturing.

Term

 

 

What structures make up the hard palate?

Definition

 

 

Maxillary and palatine bones.

Term

 

 

What is another word for Eustachian tube?

Definition

 

 

Pharyngotympanic tube

Term

 

 

Where is the soft palate and what is it's job?

Definition

 

 

The soft palate is deep to the hard palate (behind it- an extension of it) and it's job is to assist in peristalsis when swallowing.

Term

 

 

Where is the uvula?

Definition

 

 

It is located posteriorly on the soft palate

Term

 

 

Where is the nasopharynx and what's in it?

Definition

 

 

Uppermost part of the pharynx, extends from the base of the skull up to upper surface of the soft palate. Contains 2 tonsils, Pharyngeal and tubal.

Term

 

 

Where and what is the ornopharynx?

Definition

 

 

From  the soft palate to the epiglottis and it contains the palatine and the lingual tonsils.

Term

Definition

 

 

Acidic foods, stomach acids (throwing up, regurgitating) bacterial wastes.

Term

 

 

 

How does fluoride work?

Definition

 

 

It changes the tooth chemistry to preven it from dissolving.

Term

 

 

What is the functional importance of chewing?

Definition

 

 

It is the begining of the digestive process, also, excellent example of miniaturization, smaller pieces make for easier motility (swallowing) mixes the food with saliva.

Term
Describe the anatomy of a tooth.
Definition

1)Enamel: 92% hydroxyapatite, 2 to 2.5 mm thick, hardest material in the body.

2) Dentin: Deep to the enamel, more porous than enamel, 64.5% hydroxyapatite. Extends down into root, hard material of root.

3) Pulp cavity: Inside the dentin, contains the nerves and the vascular supply.

Term

 

 

What are dental nerves sensitive too?

Definition

 

 

Pressure and temperature.

Term

Definition

 

 

Maxillary nerve V2

Term

 

What nerve serves the teeth in the mandible?

Definition

 

 

Mandibular nerve V3

Term

 

 

What does the gingiva do?

Definition

 

 

Forms a seal against the tooth and protects the dentin.

Term

 

What is the alveolus and what is it's purpose?

Definition

 

 

It is a depression in the bone that the root of the tooth anchors to and it is form from the alveolar bone.

Term

 

 

What is cementum and what does it do?

Definition

 

 

Cementum is calcified connective tissue and it helps to anchor the tooth into the alveolus.

Term

 

 

Define periodontal ligament.

Definition

 

 

It is a continuation of the periosteum, surrounds the root of the tooth and attaches to cementum.

Term

Term

 

 

Where does the mandibular salivary gland duct open in the mouth?

Definition

 

 

This duct dumps saliva out at the angle of the mandibular bone.

Term

It opens superior to the gland itself and inferior to the tongue.
