This is another name for loss of taste. 

What is ageusia 

100

In this phase, the pharyngeal constrictor muscles relax to let the bolus pass through, while the superior and middle pharyngeal constrictors relax. 

What is the esophageal phase? 

200

These four muscles make up the masticatory muscles. 

The masseter, the temporalis, the medial pterygoid, and the lateral pterygoid. 

200

TMJ disorders affect this percent of the population. 

What is 20%
200

This set of teeth are tusk like. 

What are canines? 

200

This nerve is responsible for motor control of the tongue. 

What is the hypoglossus nerve?

200
In this phase of feeding, the bolus resides in the oropharynx. 

What is the pharyngeal phase?

300
The masticatory muscles work to elevate, protrude, and retract the mandible. This muscle is responsible for retracting the mandible. 

What is the temporalis muscle? 

300

This disorder of the TMJ is characterized by a restricted range of motion of the jaw. 

What is Trismus? 

300

Mandible protrusion can be achieved by bilateral activation of these muscles. 

What are the inferior bellies of the lateral pterygoid muscles? 

300

This gland produces mainly saliva. 

What is the submandibular gland? 

300

In this phase of feeding, the larynx remains open.  

What is the oral phase?

400

These three muscles are known as the mandible depressors. 

What is the mylohyoid, the anterior belly of the digastric, and the geniohyoid?
400

This TMJ disorder is characterized by fusion of the joint. 

What is ankylosis? 

400

This these structures located in the periodontal ligament can detect tooth motion. 

What are mechanoreceptors? 

400

This gland produces mainly mucous

What is the sublingual glands?

400

In the pharyngeal phase, this group of muscles is responsible for guiding the bolus towards the esophagus and raising the larynx. 

What are the longitudinal pharyngeal muscles? (made up of the stylopharyngeus, salpingopharyngeus and the palatopharyngeus)

500

The masticatory muscles are innervated by this cranial nerve. 

What is CN V - the trigeminal nerve?

500

The TMJ is characterized by the articulation of these three structures. 

What is the head of the condylar process + the articular disk + the mandibular fossa

500

Lateral movement while chewing can be achieved by simultaneous contraction of these six muscles. 

What are the ipsilateral temporalis, the deep masseter muscles, the contralateral superficial masseter, the medial and lateral pterygoids, and the mylohyoid muscle fibres. 

500

This type of papillae cover a large area of the tongue and have taste buds. 

What are fungiform papillae? (note: papillae are projections of the dermis containing taste buds). 

500

In this phase of feeding, activity of the thyroarytenoids and the posterior cricoarytenoid muscles is increased.

What is the pharyngeal phase?
