| Why is saliva so important? |
|
Definition
-Limits growth of bacteria
-Preserves teeth by bathing in minerals

|
Definition
| Parotid, Submandibular and Sublingual |
|
|
Term
| What are the Parotid Glands? |
|
Definition
| Glands that produce a serous fluid that makes up 25% of saliva |
|
|
Term
| Size and Location of Parotid Glands |
|
Definition
| Large gands located anterior and inferior to the ear, inbetween the masseter and the skin. |
|
|
Term
| Where do Parotid Glands secrete saliva? (which duct) |
|
Definition
| Stenson's duct, exiting the buccinator muscle near the buccal maxillary 1st/2nd molars. |
|
|
Term
| What activates the parotid gland? |
|
Definition
| Spicy foods, parasympathetic response |
|
|
Term
| Blood supply of parotid gland |
|
Definition
| Branch of the carotid artery and dumps into the jugular vein. |
|
|
Term
| Describe the submandibular glands |
|
Definition
| Produce a slightly viscous secretion that makes up 50%-60% of saliva. |
|
|
Term
| Size and Location of Submandibular Glands |
|
Definition
| Smaller than parotid, located inferior to base of tongue and posterior to floor of mouth. |
|
|
Term
| Ducts of the Submandibular gland |
|
Definition
| Secrete saliva into Wharton's Ducts, which exit into mouth on either side of the lingual frenum. |
|
|
Term
| Activation of Submandibular Gland |
|
Definition
| Stimulated by food, parasympathetic response |
|
|
Term
| Blood Supply to the Submandibular Glands |
|
Definition
|
|
Term
| How much saliva do the Sublingual Glands produce? |
|
Definition
|
|
Term
| Size and Location of Sublingual glands |
|
Definition
| Small glands, located superior to submandibular glands |
|
|
Term
| Ducts of Sublingual glands |
|
Definition
| Dump into Bartholins ducts, exit floor of mouth near sublingual caruncle |
|
|
Term
| Activation of Sublingual glands |
|
Definition
| Stimulated by food and is a parasympathetic response |
|
|
Term
| Blood supply to sublingual glands |
|
Definition
| Sublingual branches of lingual artery and drain into sublingual veins. |
|
|
Term
| What are the Minor Salivary glands? |
|
Definition
| Labial/Buccal, Palatine and Lingual Glands |
|
|
Term
| Size and Location of Labial and Buccal Glands |
|
Definition
| Very small, located in the vestibule of upper and lower lips in cheek region. |
|
|
Term
| Ducts of Labial/Buccal Glands |
|
Definition
| Distribution of ducts and openings in the vestibule of the cheek |
|
|
Term
| Histochemical nature of labial/buccal glands |
|
Definition
| Mixed glands but mostly mucous glands |
|
|
Term
| Size and location of Palatine Glands |
|
Definition
| Very small glands located in the soft palate and posterior/lateral hard palate. |
|
|
Term
| Ducts of the Palatine gland |
|
Definition
| Numerous openings in the hard and soft palate. |
|
|
Term
| Histochemical nature of Palatine glands |
|
Definition
|
|
Term
| What are the 4 lingual glands? |
|
Definition
1. Anterior: Tip of tongue
2. Von Ebner: Beneath vallate papilla
3. Posterior: Around lingual tonsils
4. Sublingual: Surrounding major sublingual gland |
|
|
Term
| How is secretion controlled? |
|
Definition
| The secretion of saliva is physiologically controlled and mediated through the parasympathetic nervous system |
|
|
Term
|
Definition
| Commonly known as dry mouth, glands secrete less saliva with age, causing difficulty with swallowing and speaking. |
|
