Oral Biology Unit 3 Study Guide

Gland

An organ that produces a specific product or secretion

Duct

A canal or passage for fluids

Major salivary glands

parotid, submandibular, sublingual

Minor salivary glands 

Labial, buccal, palatine, lingual

Largest salivary gland 

Parotid gland 

what type of saliva is secreted from the parotid gland

serous

what is the percentage of salivary volume secreted from the parotid gland

25%

Location of parotid gland 

Located on the side of the face below and in front of ear

Covering of stensons duct called

Parotid papilla

Stensons duct

From parotid gland to buccal oral cavity

Type of saliva secreted from submandibular gland

Mixed 80% serous, 20% mucous, 60-65% of total salivary volume

Where is the sublingual gland located

in front of and underneath the inferior border of the mandible

A small part extends to the mylo-hyoid muscle and lies deep to it

The remainder lies superficially to mylo-hyoid muscle

What artery is embedded into the submandibular gland

facial artery

Whartons duct of submandibular gland 

Opens into mouth at sublingual caruncle

Is the submandibular gland encapsulated

Yes

Smallest salivary gland 

Sublingual gland 

What type of saliva is produced by the sublingual gland

Mixed

What percentage of saliva is secreted from the sublingual gland

10%

Is the sublingual gland encapsulated

no 

Location of sublingual gland

beneath the sublingual mucosa in the floor of mouth

Rests of the mylo-hyoid muscle and its projection forms the sublingual fold on the floor of the mouth

Ducts of sublingual gland

Bartholin’s duct and Duct of Rivinis

Bartholin’s Duct

Major duct, opens along with Wharton’s Duct at the sublingual caruncle

Duct of Rivinus 

8-20 in number, these small ducts empty into sublingual fold 

Labial glands

Mixed glands that are found on the submucosa of the lips

Palatine glands

Purely mucous secretion found on the posterior third of the palate and soft palate 

3 groups of lingual glands

Anterior lingual glands, lingual glands of von ebner, posterior lingual glands

Anterior lingual glands

Located on apex of tongue

mainly mucous

Lingual glands of Von Ebner

Found beneath the circumvallate papillae

Purely serous

Posterior lingual glands 

Found near the lingual tonsils on the posterior third of the tongue 

Purely mucous 

Functions of the sinuses

Reduce weight of the skull

Resonance to voice 

produces mucous 

Where is the maxillary sinus located

Maxillae

Which is the largest sinus 

Maxillary sinuses

Symptoms of maxillary sinusitis

tenderness of maxillary teeth

blocked nose with discharge

Low grade temp

Headache 

Swelling of nasal mucosa 

Symptoms of a frontal sinus infection

Pressure and pain above the eyes

Symptoms of a sphenoid sinus infection

Pressure and congested feeling

hard to localize, deep in midline

Symptoms of an ethmoid sinus infection

Feeling of congestion, aching with nasal cavity area
