The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
The human nose is the first organ of the respiratory system.It is also the principal organ in the olfactory system.The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two.
The Smithsonian Institution Building (also known as "The Castle") was completed in 1855 to house an art gallery, a library, a chemical laboratory, lecture halls, museum galleries, and offices. [3] During this time the Smithsonian was a learning institution concerned mainly with enhancing science and less interested in being a museum.
By differential growth the neck elongates and new arches form, so the pharynx has six arches ultimately. Each pharyngeal arch has a cartilaginous stick, a muscle component that differentiates from the cartilaginous tissue, an artery, and a cranial nerve. Each of these is surrounded by mesenchyme. Arches do not develop simultaneously but instead ...

Entrance to the Science Museum of Virginia. A science museum is a museum devoted primarily to science.Older science museums tended to concentrate on static displays of objects related to natural history, paleontology, geology, industry and industrial machinery, etc. Modern trends in museology have broadened the range of subject matter and introduced many interactive exhibits.
Pharyngeal slits are repeated openings that appear along the pharynx caudal to the mouth. With this position, they allow for the movement of water in the mouth and out the pharyngeal slits. It is postulated that this is how pharyngeal slits first assisted in filter-feeding, and later, with the addition of gills along their walls, aided in ...
The pharynx is the region of the vocal tract below the velum and above the larynx. Vowels may be made pharyngealized (also epiglottalized , sphincteric or strident ) by means of a retraction of the tongue root .
