Q1. Classify salivary secretion?
Ans.
- Serous.
- Mucous.
- Mixed.
Q2. Classify salivary gland.
Ans.
- Parotid gland [serous].
- Submandibular [mixed predominantly mucous].
- Sublingual [mixed].
Q3. Define Anatomical opening of the parotid duct.
Ans.Parotid duct [stenson’s duct] opening is seen as a papilla in the buccal mucosa opposite the maxillary second molar.
Q4. Define Anatomical opening of Wharton’s duct [submandibular duct].
Ans. The submandibular duct opens at the sublingual papilla in the floor of the mouth.
Q5. Define salivary calculus.
Ans. It is defined as proteinaceous substances formed due to the obstruction of salivary flow, it is commonly seen in the salivary gland duct.
Q6. Define sialorrhea or ptyalism.
Ans. It is defined as excessive salivation seen in the affected patients. It can be mild intermittent or continuous profuse drooling, it can cause severe drooling, choking and social embracement to the patient.
Q7. Define sialolithiasis.
Ans. Sialolithiasis is the formation of sialolith (salivary calculi, salivary stone) in the salivary duct or the gland, restricting or the obstruction of the salivary flow.
Q8. Define sialolith.
Ans. The sialolith is a calcified mass with inorganic substance. It results from the crystallization of salivary solutes. The sialolith is yellowish white in colour, Single or multiple, may be round, ovoid, or elongated having the size of 2 cms or more in diameter.
Q9. Define sialadenitis.
Ans. It is defined as inflammation of the salivary gland. It may be a cute or chronic, the main etiology is due to bacterial or viral infection.
Q10. Define Mucocele.
Ans. It is defined as salivary sweating due to obstruction of salivary gland duct or due to trauma.
Q11. Classify Mucocele?
Ans.
- Extravasation type.
- Retention type.
Q12. Define ranula.
Ans. It is a type of Mucocele which occurs in the floor of the mouth. Since the lesion appears like the belly of frog it is called ranula [Rana-Frog].
Q13. Define sialadenosis.
Ans. It is non-inflammatory, non-neoplastic swelling of the salivary gland. (e.g.) Auto immune disorder, diabetes mellitus, Malnutrition.
Q14. Define Necrotizing sialometaplasia.
Ans. It is an inflammatory lesion of unknown aetiology, which affects the minor salivary glands trauma, which leads to ischemia, acinar necrosis and squamous metaplasia of ductal epithelium is through of to be the pathogenesis.
