Do dogs have an adam's apple?

A:

A dog's tongue has a structure similar to a cat's, and for a dog the top of the tongue is the part that contacts the r in the mouth. If the dog were to be seen from the side you would see a bulge of tissue on the top of the dog's tongue, but it's not an actual gland of the type you mention. Dogs have three pharyngeal tonsils:

A canine version of a human tonsil (or adenoid), they are the small, pale-yellow, swollen structures located just in front of the pharyngeal opening, on either side of the larynx. The three canine tonsils vary in size and number (one to three). The position of the tonsils and their shape remn constant and do not change with age. The number of tonsils is directly related to the size of the tongue. There is also a canine faucial tonsil that does not come into contact with the r, but rather with the faucial arches.

You can see it, but there is no real way to tell if you are right. (In general, how you know what you know is irrelevant).

That sd, I agree with the consensus that there is no distinct gland in a dog's tongue.

In dogs, the tongue is divided into the hard, smooth, mobile dorsal and

soft, smooth, mobile ventral parts. The dorsal part is covered by a

mucosal layer that is thickened over the posterior 1/3. The mucosa

thins over the anterior 1/3, forming a thin and mobile mucosa. The

tonsillar grooves lie dorsal to the tongue root. The tonsillar crypts

are located in the tonsillar fossae. The crypts are connected to each

other by a narrow channel and are composed of lymphoid tissue. In

some species, such as ferrets, the crypts of the hard palate also

contn lymphoid tissue. The crypts are connected to the crypts of the

soft palate. There are additional tonsils in dogs: the palatine tonsils

and the lingual tonsils. The palatine tonsils are the largest of the

tonsils in dogs. They are the largest and most mobile of the

tonsils. The tongue folds are not true tonsils, they are composed of

muscle, fibrous tissue, and some thin, short palisade-like processes.

The fold of the soft palate is attached dorsally, and extends

posteriorly. The fold of the soft palate is a site of adhesion to the

medial part of the vomer, and is often the site of inflammation in

dogs with chronic pharyngotonsillar disease. The fold of the soft

palate is also attached to the nasopharynx. The dorsal surface of the

tongue is smooth and covered by a mucosal layer. The mucosal layer is

covered by numerous papillae, some of which are ciliated. The

fungiform papillae are sensory buds that have taste buds.

The fungiform papillae are oval, with the broad end placed posteriorly

in the soft palate. The mucosal lining of the tongue can be easily

exposed when the tongue is pulled forward and protruded. Taste buds

are found on the undersurface of the tongue. Taste buds are oval or

cylindrical in shape. Taste buds are found near the lingual mucosal

surface. Each taste bud has three concentric rows of receptor cells.

There are two separate zones of taste buds, one near the surface and

one near the base of the taste buds. Taste buds respond to sweet,

bitter, sour, salty, and umami tastes. The tonsil is the principal

lymphoid organ of the pharynx and nasopharynx in the dog. The

crypts of the tonsil are continuous with the crypts of the soft

palate, forming the cryptopatch. There is a sublingual tonsil, which

is similar to the canine tonsil, located on the dorsum of the tongue

beneath the circumvallate papillae and fungiform papillae. The

circumvallate papillae are located in a groove on the dorsum of the

tongue. There are four grooves, each one running between three rows of

papillae. Each circumvallate papilla is oval or round in shape and is

surrounded by a shallow groove contning mucosal lymphoid tissue.

Taste buds are located on the undersurface of the circumvallate papillae.

The sublingual tonsil is located on the floor of the oral cavity

between the tongue and the gingiva. The mucosal lining of the tonsil is

composed of an overlying stratified squamous epithelium, which is

covered by nonkeratinized stratified squamous epithelium. The tonsillar

crypts are lined with the same type of epithelium as the rest of the

nasopharyngeal mucosa. The crypts are covered by a pseudostratified

ciliated columnar epithelium.

A lymphatic system is usually present within the lymphatic parenchyma

of the tonsils. The tonsillar artery is the only major artery of the

tonsil. Its branches supply the tonsil and the crypts of the tonsil and

the sublingual tonsil. Both the lingual and palatine tonsils are

directly supplied by branches of the occipital artery. The lingual

tonsil receives its blood supply from the middle meningeal artery, the

greater palatine artery, and the occipital artery. The palatine tonsil

is also supplied by the occipital artery, as well as the sublingual

tonsil.

A lymphatic network spreads into the tonsillar crypts. As in the

nasopharynx, the tonsils usually drn lymph from the tonsil into the

tonsillar crypts. The lymphatics of the tonsil extend backward into the

sublingual gland. The tonsils form an important part of the

retropharyngeal lymph nodes.

_Cellular Elements._--The cellular elements of the lymphoid tissues

are lymphocytes, macrophages, and plasma cells. The lymphocytes are

derived from the stem cells of the bone marrow. The lymphocytes are

subdivided into three classes, the small lymphocytes, the large

lymphocytes, and the intercalated cells. The small lymphocytes make up

the mn component of the white cells in the blood and in the

lymphatic tissues.
