Salivary Glands Questions: Quiz!

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.

The parotid gland is the largest salivary gland located on each side of the face, in front of the ears. It secretes saliva into the mouth through a duct called Stensen's duct. This duct opens into the vestibule, which is the area between the cheek and the upper and lower gums. The location specified in the question, opposite the maxillary 2nd molar, is consistent with the opening of Stensen's duct from the parotid gland.

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.

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.

The parotid gland is located lateral, posterior, and medial to the ramus. This means that the gland is positioned around the lower part of the ear and extends towards the back of the jawbone. The parotid gland is one of the major salivary glands and is responsible for producing saliva, which aids in the digestion of food.

The buccinator muscle is responsible for compressing the cheeks against the teeth and gums. It helps to keep food in the mouth while chewing and also aids in blowing air out of the mouth. The opening of the duct for the parotid gland is located in the buccinator muscle.

circumvallate

The serous glands of von Ebner are found in the tongue. These glands are responsible for secreting a serous fluid that helps in the digestion of food. They are located in the circumvallate papillae, which are large papillae at the back of the tongue. These glands play a crucial role in the perception of taste and the cleansing of taste buds.

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.

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.

The submandibular gland is mostly serous with some mucous acini. This means that it primarily secretes a watery fluid containing enzymes (serous) but also produces some mucus. The other glands listed, such as the buccal, sublingual, and parotid glands, have different compositions and primarily secrete either serous or mucous fluids.

The submandibular duct opens onto the sublingual caruncle. The sublingual caruncle is a small papilla located on either side of the frenulum linguae, near the base of the tongue. It is the opening for both the submandibular duct and the sublingual duct.

The sublingual caruncle is a small elevation of tissue located on the floor of the mouth, near the base of the tongue. It is the site where the submandibular duct opens into the oral cavity. Therefore, the correct answer is "on the sublingual caruncle".

increase

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.

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.

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."

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.

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.

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.

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.
