Swallowing Anaphysio Flashcards
What is mastication?
This is the process of preparing food for swallowing, also known as chewing;
Moving unchewed food onto the grinding surface of the teeth, chewing it, and mixing it with saliva
What is deglutition?
The processing of swallowing
This is the ball of food or liquid to be swallowed
Bolus
Moving unchewed food on the grinding surface of the teeth, chewing it and mixing it with saliva
Mastication
Why do we prepare the food for swallowing?
Answer: You chew to increase the food surface area –the food gets smaller but the surface area gets bigger (food surface area, meaning the area where the food is exposed to saliva or digestive enzymes). This aids in our digestion.
The act of chewing will trigger what?
The act of chewing will trigger the secretion of saliva and digestive enzymes–responsible for helping the breakdown of food in out stomach and intestine
When we say swallowing, how many phases are there?
3 but some include 4
What are the four phases of swallowing? (According to Seikel, et al.,)
Oral preparatory phase, oral stage, pharyngeal stage, esophageal stage
What are the three phases?
Oral phase, pharyngeal phase, esophageal phase
What is the oral preparatory stage?
The stage in which food is prepared for swallowing (mastication)
Stage of swallow in which the bolus is transmitted to the pharynx (propulsion of the bolus)
Oral stage
What is peristalsis?
The alternating contraction of the esophagus, responsible for propelling down the bolus to the esophagus to the stomach.
This is the roof of the mouth
Palate
Anterior part of the palate, and is known as a immobile bone. When we are chewing, the tongue rubs against this palate, thereby aiding the breakdown of the food.
Hard palate
This is the posterior part of the palate, and is a mobile muscle covered with mucous membrane. This keeps the nasal passages closed, elevating it which protects us from nasal regurgitation.
Soft palate
This is a pit “parang dimple” which is the origin of the thyroid gland. Marks the boundary between anterior ⅔ and posterior ⅓ of the tongue. This is where the thyroid gland originated from.
Foramen cecum
Taste buds are located at the palate. True or False.
True
The midline groove on our tongue or sulcus is called
Sulcus terminalis
What are faucial pillars?
Serve as boundary between oral cavity and pharynx
Difference between anterior pillars and posterior pillars
Anterior pillar are palatoglossal arches palato - palate, glossal - tongue, extend from soft palate to the sides of the tongue
Posterior pillars are palatopharyngeal arches, which extend from soft palate to the walls of the throat
Which mucous membrane builds up the anterior pillars?
Palatoglossus mucous membrane
Which mucous membrane counterparts the anterior pillars?
Palatopharyngeus mucous membrane
What is the eustachian tube?
This is an auditory tube also known as the pharyngotympanic tube which connects the middle ear to the back of the nose and throat (nasopharynx)
Equalizes pressure of the middle ear
It is a funnel-shaped conductive structure that is shared by the GIT and respiratory system
Ends at the level of C6 (where esophagus starts)
Pharynx
