The columella

The opening of the nasal cavity starts with vibrissae(catches large particles) and transitions to...

ciliated mucous membranes (trap dust/mucous)

The nasal cavity is split by the septum and its anterior portion holds the...

Kiesselbach complex, a blood vessel rich network , common site of nosebleeds

Lateral walls of the nasal cavity are lined by

Superior/middle/inferior turbinates which increase surface area to warm/filter inhaled air

Underneath each turbinate is the meatus where what happens?

Sinuses drain out of middle meatus

Tears drain from nasolacrimal duct via inferior sinus

The olfactory hair cells line upper part of nasal cavity and transition into...

cranial nerve one, and terminate in temporal lobe

What purpose do para-nasal sinuses serve?

(Hint: they are lined with ciliated mucous membranes like the nasal cavity)

1) Lighten weight of skull

2) Secrete mucus that drains into middle meatus

3) Help resonate sounds

What/where at the 4 para-nasal sinuses?

Ethmoid: between eye orbits, within ethmoid bone

Sphenoid: deep in skull, posterior to ethmoid

Frontal: bilateral, above and medial to eye orbits

Maxillary: bilateral, just below eye orbits on either side of nose

Describe anatomy of mouth

Roof is palate, divided into anterior hard palate and posterior soft palate (note: soft palate has some tastebuds)

Tongue is a striated, crosswise muscle so it can change shape/position, connected to floor of mouth by frenulum. Taste buds line the side and the vallate papillae at the back of the tongue.

Describe the three pairs of salivary glands

Largest= parotid, triangular shaped, stretches from front of ear to angle of jaw--Stensen duct is its drain, exits just opposite the second molar

Sub-Mandibular= walnut size, rests below angle of jaw, whartons duct is its drain, exits at base of frenulum

Sub-lingual: almond sized, rests at floor of mouth under tongue, has numerous exit ducts along tongue base

How many teeth do humans have? Describe their basic anatomy and arrangement in gum line .

32 total, 16 above and below, teeth are described to have a crown, neck, and root

Central incisor-->lateral incisor-->canine-->1st premolar-->2nd premolar-->then 1st, 2nd, and 3rd molars respectively

The tonsil pillars are the dividing line between oral cavity and the...

oropharynx. Tonsils contain lymphoid tissue as 1st line defense against micro-organisms

What is bruxism?

Teeth grinding, usually occurs in sleep (nervous tension or dental problem etiology)

Does chronic tobacco use affect teeth

Yes, significant risk for gum disease/atrophy, dental caries

Does saliva production decrease with age?

Yes, however the major cause of xerostomia is the increased use of anticholinergics in later years.

When inspecting for oral malignancies, where is the most likely place they develop?

Area under the tongue and behind the teeth...any lesion older than 2 weeks must be investigated

Dappled, brown patches on buccual mucosa indicate?

Presence of addisons disease (chronic adrenal insufficiency)
