Why do the auditory tubes open into the nasopharynx? To clear mucus from the middle ear into the nasopharynx.
What are the 7 openings of pharynx?
Seven cavities communicate with it, viz., the two nasal cavities, the two tympanic cavities, the mouth, the larynx, and the esophagus. The cavity of the pharynx may be subdivided from above downward into three parts: nasal, oral, and laryngeal (Fig.
What does the laryngopharynx do?
The laryngopharynx, also referred to as the hypopharynx, is the most caudal portion of the pharynx and is a crucial connection point through which food, water, and air pass. Specifically, it refers to the point at which the pharynx divides anteriorly into the larynx and posteriorly into the esophagus.
What are the three parts of the pharynx and their functions?
The pharynx anatomy includes:
- Nasopharynx: The top part of the throat connects to the nasal cavities (nose) and lets air pass through.
- Oropharynx: The middle part of the throat connects to the oral cavity (mouth). …
- Laryngopharynx (or hypopharynx): The bottom part of the throat is near the larynx (or voice box).

Where are the openings of the auditory tubes?
The opening of the auditory tube (which leads to the middle ear) lies on the dorsolateral wall of the nasopharynx.
What are the 3 functions of the pharynx?
It: Carries air to the respiratory system. Delivers food and liquid to the digestive system. Pushes food into the esophagus so it's not breathed in.
Where are the openings of the auditory tubes located?
The pharynx communicates with the: Choanae: the paired openings between the nasopharynx and the nasal cavity. Pharyngeal openings of the auditory tube located in the lateral walls of the nasopharynx.
What opens auditory tube?
The muscles of the eustachian tube system help open and close the tube, thus allowing it to perform its function. These muscles are the (1) tensor veli palatini, (2) levator veli palatini, (3) salpingopharyngeus, and (4) tensor tympani.
What is the glottic opening?
The glottis is the opening between the vocal folds in the larynx that is generally thought of as the primary valve between the lungs and the mouth; the states of the glottis are the positions generally considered to characterize the different possible shapes of this opening.
What is nasopharynx oropharynx and laryngopharynx?
The oropharynx is the middle chamber of the pharynx that passes food from the mouth into the laryngopharynx. The nasopharynx opens above it as well. The laryngopharynx is the bottom part of the pharynx that marks the branching pathway between the digestive and respiratory systems.
Where is the pharynx and how did it become an important part of human sound production?
Where is the pharynx and why did it become an important part in the human sound production? The pharynx is above the larynx (or the voice box of the oral box). When the larynx moved lower, the pharynx became longer and acted as a resonator, resulting in increased range and clarity of sounds produced via the larynx.
Where is the opening of the auditory tube located quizlet?
The openings of the Eustachian or auditory tubes are located in the region. The portion of the pharynx between the soft palate and the epiglottis. It is the common passageway for the digestive and respiratory systems.
What two regions are connected by the auditory tube?
In anatomy, the Eustachian tube, also known as the auditory tube or pharyngotympanic tube, is a tube that links the nasopharynx to the middle ear, of which it is also a part.
What is the opening between vocal cords?
Glottis – This is the space between the two vocal folds. When the vocal folds adduct, the glottis closes; when the vocal folds abduct, the glottis opens. The adjectives "glottal" and "glottic" are used to describe many aspects of vocal fold movement. The glottis opens and closes during vibration.
Where is the Vallecula Epiglottica located?
The epiglottic vallecula consists of a small mucosa-lined depression (vallecula) located at the base of the tongue just between the folds of the throat on either side of the median glossoepiglottic fold. It is usually not seen by the naked eye as it is far back and deep at the root of the tongue.

What is called the upper region of pharynx in man?
The upper portion of the pharynx, the nasopharynx, extends from the base of the skull to the upper surface of the soft palate. It includes the space between the internal nares and the soft palate and lies above the oral cavity.
Where is the opening of the distal auditory tube located?
The tube opens about 1.25 cm behind and slightly below the posterior end of the inferior turbinate. The bony portion is widest at its tympanic end. It passes through the squamous and petrous portions of the temporal bone but narrows gradually to the isthmus, which is the narrowest part of the eustachian tube.
