AS&RM
| Question | Answer |
|---|---|
| What does supra mean? | above |
| What does glottic mean? | Glottis (space between vocal folds) |
| What does Supraglottic deal with? | structures above the glottis |
| What does biological function mean? | a function needed to sustain life |
| What is the function of the respiratory tract? | it filters, warms, and moistens incoming air either through the mouth or nose |
| What does the Alimentary tract do? | provides nourishment, helps with chewing and swallowing |
| What is the alimentary track? | mouth, esophagus, and rest of the digestive system |
| What is another name for chewing? | mastication |
| What is another name for swallowing? | deglutition |
| What is dysphagia? | problems with swallowing |
| Which airway warms air better, but takes longer to reach the lungs? | the nasal airway |
| Why does the nose warm air better? | Because of mucosa |
| What is resonance? | deals with the hyper- or hypo- nasal qaulity of speech |
| What is the source for speech? | the laryngeal system |
| Speech is NOT | a biological function |
| What is the power for speech? | the lungs |
| What is the filter for speech? | the supraglottic airway |
| What is another name for the supraglottic airway? | the vocal tract |
| What are the three sections of the Pharyngeal cavity? | the laryngopharynx, the oropharynx, and the nasopharynx |
| What is another name for the laryngopharynx? | the hypopharynx |
| What is the laryngopharynx? | the most inferior section where the laryngeal system meets the pharynx, continuous with the larynx and esophagus, extends superiorly to the hyoid bone |
| What are adenoids? | lymphoid tissue that is located on the posterior wall of the nasopharynx |
| What is the oropharynx? | the cavity behind the oral cavity, superior to the laryngopharynx, goes from the soft palate to the level of the hyoid bone |
| What is the nasopharynx? | the cavity behind the nasal cavity, bounded superiorly by the base of the skull, the inferior border is the soft palate, contains adenoids, eustachian tube, and pharyngeal recess |
| What are other names for the nasopharynx? | the epipharynx or velopharynx |
| What are structures found in the Pharyngeal cavity? | the eustachian tube, pharyngeal recess, torus tubarius, and salpingopharyngeal fold |
| What is another name for the eustachian tube? | the auditory tube |
| What is the course of the eustachian tube? | runs from the nasopharynx to the middle ear cavity, opening is right at the torus tubarius |
| What is the eustachian tube? | a flat tube that allows for ear drainage and pressure equalization of the middle ear, in the Pharyngeal cavity |
| Why is the eustachian tube flat? | so things within the nasal cavity do not enter |
| What is the Pharyngeal recess? | a deep groove behind the torus tubarius, in the Pharyngeal cavity |
| What is another name for the Pharyngeal recess? | The fossa of Rosenmuller |
| What is the torus tubarius? | a ring of cartilage that surrounds the opening of the eustachian tube in the Pharyngeal cavity |
| What is the salpingopharyngeal fold? | a fold of tissue that extends inferiorly beyond the torus tubarius in the Pharyngeal cavity |
| What is the salipngopharyngious? | the muscle that helps open the eustachian tube |
| What bounds the Pharyngeal cavity posteriorly? | the cervical vertebrae |
| What does the Pharyngeal cavity do during speech? | it does not change much normally, just for low vowel sounds |
| What is posterior to the oral cavity? | the oropharynx |
| How does the oral cavity change during speech? | it changes shape considerably to help with speech production |
| What are faucial pillars? | the sides of the oral cavity that make an M with the uvula, has anterior and posterior versions |
| What is the fauces of the oral cavity? | the space between the anterior and posterior faucial pillars where the Palestine tonsils sit |
| What is another name for the fauces of the oral cavity? | the faucial isthmus |
| What cavity includes the posterior faucial pillars and everything behind it? | the oropharnyx |
| What cavity includes everything in front of the posterior faucial pillars? | the oral cavity |
| What does ankyloglossia mean? | directly translates to anchored tongue, is commonly known as a tongue tie |
| What is a labial or lingual frenulum? | the little attachments from the lips to gums or tongue to the base of the mouth |
| What does labial mean? | lips |
| What does lingual mean? | tongue |
| When is a cut of the lingual frenulum needed? | for oral hygiene or feeding, not usually needed for speech (but happens anyway) |
| What is the nasal cavity joined by posteriorly? | the nasopharynx |
| The nasopharynx is singular, but the nasal cavity is...? | paired |
| The nasal cavity is paired, but the nasopharynx is...? | singular |
| What is a choanae? | the entrance to the pharynx from the nasal cavity, very small |
| What is a nasal conchae? | the bony segments in the nasal cavity |
| How many nasal conchae do we have? | three total |
| What are the names of the nasal conchae? | superior, middle, and inferior |
| What is a conchae referring to? | the bone itself |
| What is a turbinate referring to? | the bone and mucosa covering it |
| What is a meatus of the nasal cavity? | each space under the nasal conchae |
| Which meatus of the nasal cavity is usually the biggest? | the middle, where covid tests were SUPPOSED to go |
| What are the names of the meatuses of the nasal cavity? | superior, middle, and inferior |
| What is covering the nasal cavity? | a mucous membrane/mucosa |
| What is the midline of the nasal cavity? | the nasal septum |
| What is the nasal septum made of? | two bones and one cartilage |
| What happens to the nasal cavity during speech? | it does not change shape but transmits energy for /m, n, ŋ/ |
| What are paranasal sinuses? | different pockets located around the body that communicate with the nasal cavity, influence speech sounds through resonance, and why we sound different when we are sick |
| What is the buccal cavity? | the small space bounded externally by the lips and cheeks and internally by the gums and teeth. |
