Module 2 Landmarks of the face and Oral Cavity (4) and Salivary Glands (5)

What are the different papillae of the tongue?

Vallate papilla

• is a upside down V shaped formation in the back of the tonguw (posterior)

Foliate papilla

• is a folded like tissue on the lateral surfaces of the tongue (sides)

Fungiform papilla

• Is more rounded tissues, red in color

• need to be maintained to prevent overgrowth

• have taste buds

Filiform papilla

• the longer thread like tisue

• provide the sense of touch

Where are taste buds present?

In the FUNGIFORM and VALLATE papillae

What are the functions of saliva?

• Lubrication

• protection

• digestion

• antibacterial

• remineralization

What is a salivary gland?

• is an exocrine gland that secretes saliva into the oral cavity

What is a duct?

• a pasageway from the sailvary gland to the destination (oral cavity) of the secretions

What are the 3 major salivary glands?

• Parotid gland

• Submandibular gland

• Sublingual gland

Describe the parotid gland

• Is the largest

• produces 25% of saliva (not a lot)

• Dump into the mouth via the STENSON'S DUCT at the PAROTID PAPILLA (in the buccal mucosa,next the the 2nd molar)

Describe the Submandibular gland

• is the second largest

• Is beneath the mandible and tucked into the submandibular fossa

• Is posterior to the sublingual gland

• Produces 60-65% fo saliva (large producer of saliva)

• Dumps into the mouth via the WHARTON'S DUCT which ends in the SUBLINGUAL CARNICLES

Describe the Sublingual gland

• Is the smallest

• Is underneath the tongue in the anterior poriton

• Produces 10% of saliva

• Dumps into the mouth via the BARTHOLIN'S DUCT along the SUBLINGUAL FOLD

How do minor salivary glands compare to the majot salivary glands?

• There are numerous of them, smaller, and scattered all thorughout the mouth

• They ensure tha the mouth is kept moist
