21
Q

How are the major salivary glands categorized?

A

By their location and structure

They are paired, encapsulated glands.

22
Q

What is the function of the Parotid Gland?

A

Produces saliva to aid in digestion and oral health

It is the largest salivary gland.

23
Q

Fill in the blank: The _______ gland is also known as the Submaxillary Gland.

A

Submandibular

24
Q

True or False: The Sublingual Glands are located beneath the tongue.

A

True

Their position allows for rapid saliva secretion.

25
Q

What is the largest of the three major salivary glands?

A

Parotid gland

The parotid gland is the largest salivary gland, located on the side of the face near the ear.

26
Q

What percentage of saliva does the parotid gland produce?

A

Approximately 25%

This indicates the parotid gland’s contribution to overall saliva production.

27
Q

Where is the parotid gland located?

A

On the side of the face near the ear, behind the ramus

The specific anatomical positioning of the parotid gland is important for understanding its function and potential medical issues.

28
Q

What is the name of the duct associated with the parotid gland?

A

Stenson’s Duct

Stenson’s Duct is also referred to as the parotid duct, and it plays a key role in saliva drainage.

29
Q

Which muscle does Stenson’s Duct pierce?

A

Buccinator muscle

The buccinator muscle is located in the cheek and aids in the function of the parotid gland.

30
Q

What is the anatomical relationship of Stenson’s Duct to the masseter muscle?

A

Superficial to the masseter muscle

This positioning is relevant for surgical approaches and understanding potential complications.

31
Q

Fill in the blank: The parotid gland is responsible for producing _______ of saliva.

A

approximately 25%

This figure reflects the gland’s significant role in saliva production.

32
Q

True or False: The parotid gland is located underneath the jaw.

A

False

The parotid gland is actually located on the side of the face near the ear, not underneath the jaw.

33
Q

What is the largest of the three major salivary glands?

A

Parotid gland

Q

Fill in the blank: The parotid gland is responsible for producing _______ of saliva.

A

approximately 25%

This figure reflects the gland’s significant role in saliva production.

40
Q

True or False: The parotid gland is located underneath the jaw.

What type of secretions does the parotid gland produce?

A

Pure serous

42
Q

Where is the orifice of the parotid gland located?
