Glandula parotidea

The video tutorial provides an in-depth look at the parotid gland, the largest salivary gland in the head. It covers the gland's anatomy, location, and function, including its role in saliva production. The tutorial explains the gland's anatomical position, its blood supply, and the complex nerve innervation, detailing the sensory, parasympathetic, and sympathetic pathways. The video also describes the pathway of saliva from the gland to the oral cavity and highlights the continuous production of saliva, even between meals.

What is the primary function of the parotid gland?

• To produce digestive enzymes

• To produce saliva

• To filter blood

• To regulate body temperature

Where is the parotid gland located?

• In the chest cavity

• On either side of the head

• In the abdominal cavity

• In the lower back

What is the name of the duct that carries saliva from the parotid gland to the oral cavity?

• Ductus Parotideus

• Stensen's duct

• Wharton's duct

• Sublingual duct

Which arteries supply blood to the parotid gland?

• Femoral and brachial arteries

• Carotid and radial arteries

• Maxillary and superficial temporal arteries

• Pulmonary and aortic arteries

Which nerve is responsible for the parasympathetic innervation of the parotid gland?

• Hypoglossal nerve

• Vagus nerve

• Glossopharyngeal nerve

• Facial nerve

What effect does the sympathetic nervous system have on saliva production?

• Changes the composition of saliva

• Increases saliva production

• No effect on saliva production

• Decreases saliva production

What triggers the production of saliva in the parotid gland?
