The parasympathetic nervous system controls salivary gland secretion.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The parasympathetic nervous system controls salivary gland secretion. This is because the parasympathetic division of the autonomic nervous system is responsible for regulating rest and digestion. When activated, it stimulates the salivary glands to produce saliva, which aids in the digestion process. Therefore, the statement is true.Rate this question:

Major salivary glands are purely or mostly mucous in nature.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The major salivary glands, such as the parotid, submandibular, and sublingual glands, are predominantly composed of mucous cells. These cells secrete a thick and viscous fluid called mucus, which helps to lubricate and protect the oral cavity. Mucous cells produce a type of saliva that is rich in mucins, glycoproteins that give mucus its characteristic slimy texture. Therefore, it is correct to say that the major salivary glands are mostly mucous in nature.Rate this question:

Major salivary glands are compound tubuloalveolar glands.
- A.
True
- B.
FALSE
Correct Answer
A. TrueExplanation
Major salivary glands are compound tubuloalveolar glands. This means that these glands have both tubular and alveolar structures. Tubular structures refer to the presence of small tubes or ducts within the gland, while alveolar structures refer to the presence of small sac-like structures called alveoli. The combination of these structures allows the major salivary glands to produce and secrete saliva, which is essential for digestion and oral health. Therefore, the statement is true.Rate this question:

Submandibular gland.
Correct Answer
mostly serousExplanation
The submandibular gland is mostly composed of serous cells. Serous cells are responsible for producing a watery secretion that contains enzymes, electrolytes, and other proteins. This type of secretion helps in the digestion and breakdown of food. Therefore, the correct answer is that the submandibular gland is mostly serous.Rate this question:
- 10.
Sublingual gland.
Correct Answer
mostly mucousExplanation
The sublingual gland is predominantly composed of mucous cells. This means that it secretes a thick, viscous fluid rich in glycoproteins called mucins. Mucous cells play a role in lubricating and protecting the oral cavity, as well as aiding in the initial stages of digestion by moistening food particles. Other salivary glands, such as the parotid and submandibular glands, have a higher proportion of serous cells, which secrete a watery fluid containing enzymes. However, the sublingual gland is known to have a higher concentration of mucous cells, hence the description "mostly mucous."Rate this question:
- 11.
Parotid gland.
Correct Answer
purely serousExplanation
The parotid gland is a major salivary gland located near the ear. It produces saliva, which helps in the digestion of food. The term "purely serous" refers to the type of cells present in the gland. Serous cells produce a watery secretion that contains enzymes, electrolytes, and antibodies. Therefore, the correct answer indicates that the parotid gland is composed of serous cells that produce a watery secretion.Rate this question:
- 12.
Gland of von ebner
Correct Answer
purely serousExplanation
The gland of von Ebner is a salivary gland located in the tongue. It is known for secreting a purely serous type of saliva. Serous saliva is thin and watery, containing enzymes such as amylase that aid in the digestion of carbohydrates. This type of saliva is different from mucous saliva, which is thicker and provides lubrication. Therefore, the correct answer is "purely serous" as it accurately describes the type of saliva secreted by the gland of von Ebner.Rate this question:
- 13.
Anterior lingual gland.
Correct Answer
mostly mucousExplanation
The correct answer is "mostly mucous." This suggests that the anterior lingual gland predominantly secretes a mucous substance. Mucous is a viscous fluid that helps to lubricate and protect the oral cavity, making it easier for food to be swallowed.Rate this question:

The submandibular gland is also called the:
- A.
Submaxillary
- B.
Mandibular
- C.
Sublingual
- D.
Lingual
Correct Answer
A. SubmaxillaryExplanation
The submandibular gland is also known as the submaxillary gland. Both terms refer to the same salivary gland located beneath the mandible (lower jaw). The gland produces saliva that helps in the digestion process. The term "submaxillary" is derived from the Latin words "sub" meaning under and "maxilla" meaning jawbone, indicating its location. Therefore, the correct answer is submaxillary.Rate this question:

Which structure does not have minor salivary glands?
- A.
Tongue
- B.
Anterior hard palate
- C.
Labial mucosa
- D.
Buccal mucosa
Correct Answer
B. Anterior hard palateExplanation
The anterior hard palate does not have minor salivary glands. Salivary glands are responsible for producing saliva, which helps in the process of digestion. The tongue, labial mucosa, and buccal mucosa all contain minor salivary glands. However, the anterior hard palate, which is the front part of the roof of the mouth, does not have these glands.Rate this question:

Which of the following is not true of minor salivary glands?
- A.
Less branching
- B.
Short ducts
- C.
Fewer duct openings
- D.
Keep mucous membranes moist
Correct Answer
C. Fewer duct openingsExplanation
Minor salivary glands are small glands located throughout the oral cavity that secrete saliva. They have short ducts, meaning that the distance between the gland and the opening where saliva is released is relatively short. Additionally, they help keep the mucous membranes moist, which is important for maintaining oral health. However, it is not true that minor salivary glands have fewer duct openings. In fact, they have numerous duct openings that allow for the secretion of saliva into the oral cavity.Rate this question:

The nerve supply to all salivary glands comes from the:
- A.
Autonomic nervous system
- B.
Parasympathethic nervous system
- C.
Sympathetic nerous system
- D.
A and b
- E.
A and c
Correct Answer
E. A and cExplanation
The nerve supply to all salivary glands is provided by both the autonomic nervous system and the sympathetic nervous system. The autonomic nervous system as a whole includes both the parasympathetic and sympathetic divisions, which play complementary roles in the function of the salivary glands.
The parasympathetic nervous system primarily stimulates salivation, promoting the secretion of saliva which is rich in enzymes and aids in digestion.
The sympathetic nervous system contributes by influencing the blood flow to the glands and slightly altering the composition of the saliva, generally reducing the volume of saliva produced but making it more rich in mucous.
Thus, the correct answer reflects the involvement of both the autonomic nervous system as a whole (including the parasympathetic division) and the sympathetic nervous system specifically in regulating the activity of the salivary glands.Rate this question:

Which of the following major salivary glands has more than one duct?
- A.
Parotid
- B.
Submandibular
- C.
Sublingual
- D.
Both a and b
- E.
Both a and c
Correct Answer
C. SublingualExplanation
The sublingual gland is the major salivary gland that has more than one duct. This gland is located underneath the tongue and has multiple small ducts that secrete saliva into the mouth. The parotid gland, on the other hand, has a single duct called the Stensen's duct, while the submandibular gland has a single duct called the Wharton's duct. Therefore, the correct answer is sublingual.Rate this question:
