(a) What is the structure of the macula in the ear? (b) What is its function? What structure has external nares? What is the role of the epiglottis? Describe the structure of the larynx. What structures in the mouth play a role in mechanical and chemical digestion?
It was found that the histology as well as the ultrastructure of the secretory product of these gland cells varied depending upon the location of the glands in the airway. For this reason, the glands of the epiglottis, larynx and trachea have been described separately. Epiglottal glands ...
What structure has epiglottis? How is fluid balance associated with liver disease? What are the functions of each organ of the gastrointestinal tract and of the accessory glands: liver, gallbladder, and pancreas? (a) Describe the structure of the nasopharynx. (b) What is its function? What ...
Food and fluids from the pharynx usually are prevented from entering the larynx by the epiglottis, a thin, leaflike tissue. The “stem” of the leaf attaches to the front and top of the larynx. When a person is breathing, the epiglottis is held in a vertical position, like an open trap...
The laryngopharynx (or hypopharynx) extends from inferior to the superior border of the epiglottis and the pharyngoepiglottic folds to the superior border of the cartilage. The hypopharynx communicates with the larynx anteriorly. There are two groups of muscles in the wall of the pharynx, the ...
epiglottis- a flap of cartilage that covers the windpipe while swallowing auricle,pinna,ear- the externally visible cartilaginous structure of the external ear tragus- a small cartilaginous flap in front of the external opening of the ear
Food and fluids from the pharynx usually are prevented from entering the larynx by the epiglottis, a thin, leaflike tissue. The “stem ” of the leaf attaches to the front and top of the larynx. When a person is breathing, the epiglottis is held in a vertical position, like an open ...
The junction of the oropharynx at the level of the hyoid bone (often near the top of the epiglottis). Inferior Boundary: The transition point at the cricopharyngeus muscle (the upper esophageal sphincter), where the hypopharynx merges into the cervical esophagus. ...
Fig. 7 shows the constructed 3D structure of airway, tongue, soft palate, mandible, hard palate, nasal cavity, epiglottis, cricothyroid cartilage, trachea, skull, skin, etc., based on multi-directional cross-sectional images. The adjacency or contact between the tissues was accurately represented...
Nasal pharynx:It is the anterior portion or back of the throat, it is connected to the next section through a passageway called the isthmus. Oral pharynx:It begins at the back of the mouth which continues down to the epiglottis. Laryngeal pharynx:It begins at the epiglottis region and contin...
