Swallow A&P

Cranial Nerves

100

This CN is motor only and responsible to tongue movement 

XII Hypoglossal 

200

This Cranial Nerve is responsible for sensory and motor function in the larynx, pharynx, and esophagus

X Vagus Baby! 

300

Cranial nerves are part of the _________ nervous system 

peripheral 

400

Muscles of chewing (mastication) are innervated by CN 

V Trigeminal 

500

The labial muscles (obicularis oris) are innervated by CN 

VII Facial 

Oral Phase

100

This cavity / area is located on the lingual side of the epiglottis

valleculae 

200

the superior and inferior longitudinal muscles are intrinsic muscles of the 

tongue 

300

Dysfunction of this structure may result in nasal regurgitation.

vellum / soft palate 

400

digastric and mylohyoid muscles are located on the floor of the mouth and are extrinsic muscles of the 

Tongue 

500

These muscles of the cheek compress the oral cavity to prevent pocketing 

buccinators 

Pharyngeal Phase

100

this forms the opening to the esophagus 

UES 

200

Aspiration occurs when the bolus travels into the 

trachea 

300

These spaces or recesses are located at the bottom of the hypopharynx, near the esophageal inlet.

pyriform sinuses 

400

This set of 3 muscles contract sequentially and send the bolus inferiorly through the throat towards the esophagus

upper middle and inferior pharyngeal constrictors 

500

The cricopharyngeus muscle is also called the 

Upper Esophageal Sphincter 

larynx

100

This bone is connected to no other bone but is a point of origin or insertion for a number of muscles involved in swallowing

Hyoid 

200

This structure is characterized by the presence of cartilaginous rings

trachea 

300

This cavity / area is located on the laryngeal side of the epiglottis.

Laryngeal vestibule 

400

The 3 cartilages that make up the larynx are

thyroid, cricoid, arytenoids 

500

The supraglottis is the area above the 

vocal folds / glottis 

MISC.

100

When completing Simucase studies, I will use _______ mode. 

learning 

200

There are 3 phases of the swallow including oral phase, pharyngeal phase, and the _________________.

esophageal phase 

300

The primary structure for the neurologic control of the swallow is the 

brainstem 

400

NPO means 

nothing per oral (nothing by mouth) 

500

Dysphagia with aspiration may lead to 

aspiration pneumonia
