Question 1

Which of the following glands can be palpated within the sublingual space in the floor of the mouth?

Accepted Answer

The sublingual gland is located within the sublingual space in the floor of the mouth and can be palpated. The parotid gland is located in front of the ear and cannot be palpated within the floor of the mouth. The parathyroid gland is located on or near the thyroid gland and also cannot be palpated within the floor of the mouth. The submandibular gland is located in the submandibular triangle and cannot be palpated within the sublingual space.

Question 2

Which of the following nerves can be damaged during surgery on the submandibular salivary gland?

Accepted Answer

The lingual nerve supplies sensory innervation to the anterior 2/3 of the tongue and can be damaged during surgery on the submandibular salivary gland due to its close proximity. The cervical nerve supplies sensory innervation to the skin of the neck, the inferior alveolar nerve supplies sensory innervation to the mandibular teeth and lower lip, and the mental nerve supplies sensory innervation to the lower lip and chin, but are not typically at risk during submandibular gland surgery.

Question 3

The lacrimal glands are considered exocrine glands because their secretion enters directly into the vascular system without the use of any ducts.

Accepted Answer

The statement is correct as tears secreted by lacrimal glands enter directly into the vascular system. However, the reason provided is not entirely correct as exocrine glands are defined by the fact that they secrete their products through ducts, while endocrine glands secrete products directly into the bloodstream. Therefore, the reason does not support the statement.

Question 4

Which of the following glands wraps around the mylohyoid muscle?

Accepted Answer

The submandibular gland wraps around the mylohyoid muscle.

Question 5

Which of the following nerves when damaged can affect the production of the serous type of saliva?

Accepted Answer

The ninth cranial nerve, also known as the glossopharyngeal nerve, innervates the parotid gland, which produces the serous type of saliva. Damage to this nerve can affect the production of serous saliva. The chorda tympani and greater petrosal nerves are branches of the seventh cranial nerve, which innervate the sublingual and submandibular glands, respectively, producing the mixed type of saliva.

Question 6

Which of the following nerves innervates the minor salivary glands?

Accepted Answer

The answer of Which of the following nerves innervates the...

Question 7

At which of the following bony junctions does the nasolacrimal duct begin?

Accepted Answer

The nasolacrimal duct begins at the junction of the maxilla and lacrimal bone, where tears from the lacrimal sac drain into the nasal cavity.

Question 8

If there is an infection involving the submandibular salivary gland, what lymph nodes would be initially involved?

Accepted Answer

The submandibular salivary gland drains primarily into the submandibular lymph nodes.

Question 9

Which of the following lingual papillae are DIRECTLY associated with salivary glands?

Accepted Answer

The answer of Which of the following lingual papillae are...

Question 10

What is the location for the parathyroid glands?

Accepted Answer

The parathyroid glands are typically located on or within the posterior surface of the thyroid gland. They are small, typically four glands, and are responsible for regulating calcium levels in the body.

Question 11

Which of the following lymph nodes are initially involved when the patient has contracted mumps?

Accepted Answer

Mumps virus primarily affects the parotid glands, so the initial lymph nodes involved would be the deep parotid nodes.

Question 12

Which of the following glands is associated with the pterygopalatine ganglion?

Accepted Answer

The pterygopalatine ganglion is associated with the lacrimal gland, which is responsible for producing tears. This ganglion also provides innervation to other structures in the face, such as the nasal glands and palate. The parotid gland is associated with the otic ganglion, while the sublingual and submandibular glands are associated with the submandibular ganglion.

Question 13

Which of the following glands is associated with Wharton's duct?

Accepted Answer

Wharton's duct is also known as the submandibular duct, and it is associated with the submandibular gland, which is choice D.

Question 14

Which of the ducts when blocked is involved in the formation of a ranula in the posterior floor of the mouth?

Accepted Answer

Wharton's duct is located in the submandibular gland and is responsible for draining saliva into the mouth. When it becomes blocked, saliva can accumulate and form a cyst known as a ranula in the posterior floor of the mouth. Bartholin's duct is located in the vulva and is responsible for the secretion of lubricating fluid. Nasolacrimal duct is located in the eye and is responsible for draining tears. Stensen's duct is located in the parotid gland and is responsible for draining saliva into the mouth.

Question 15

Both the major and minor salivary glands are _______ glands.

Accepted Answer

Salivary glands are exocrine glands, which means that they secrete their products (in this case saliva) through a duct that leads to a specific site (in this case the oral cavity). Endocrine glands, on the other hand, secrete their products (hormones) directly into the bloodstream. The terms "large" and "small" are not accurate descriptors for salivary glands, as some major salivary glands (such as the parotid glands) are larger than some minor salivary glands.

Question 16

Which of the following glands can be palpated as part of an extraoral examination?

Accepted Answer

The thyroid gland is located in the neck and is often palpable during an extraoral examination. The lacrimal gland is located near the eye and cannot be palpated. The parathyroid gland is located on the back of the thyroid gland and is not typically palpable. The thymus gland is located in the chest and is not palpable during an extraoral examination.

Question 17

Which of the following glands secrete only a serous type of saliva?

Accepted Answer

The parotid gland secretes serous type saliva only, while von Ebner's gland secretes only serous type saliva for taste perception. Submandibular and sublingual glands secretes both serous and mucous type of saliva.

Question 18

Which of the following glands listed below is NOT an endocrine gland?

Accepted Answer

The lacrimal gland is responsible for producing tears, which lubricate and protect the eyes. However, it is not an endocrine gland as it does not secrete hormones into the bloodstream. The parathyroid, thyroid, and thymus glands are all endocrine glands.

Question 19

Which of the following exocrine glands produces 60% to 65% of the total volume of saliva for the oral cavity?

Accepted Answer

The submandibular gland produces 60% to 65% of the total volume of saliva for the oral cavity. The sublingual gland produces 10% to 15%, while the parotid gland produces 25% to 30%. The lacrimal gland is responsible for producing tears.

Question 20

Which type of secretion is produced from MOST minor salivary glands within the oral cavity?

Accepted Answer

Most minor salivary glands within the oral cavity produce mainly mucous secretion.
