	Curing bad breath with the help of a tongue scraper.
		For this reason it is typically the posterior aspect of the tongue that is found to harbor the bacteria that cause a person's bad breath, and thus the posterior tongue is the most important area to clean.
		They revealed that the smell of the anterior portion of a person's tongue is usually less offensive than the smell found emanating from the posterior part.
		While cleaning your tongue with a brush can be satisfactory, many people find that scraping their tongue with a tongue scraper is more effective.

	Tongue - Wikipedia, the free encyclopedia
		The dorsum (top side) of the tongue can be divided into two parts, a pharyngeal part (posterior third of the tongue), which faces backward to the oropharynx, and an oral part (anterior two-thirds of the tongue) that lies mostly in the mouth.
		Tongue rolling is thus a commonly explored experiment in highschool and introductory biology courses, as students examine it as a demonstrative concept for inheritance and in the initial understanding of genotypes and phenotypes.
		The tongue is made mainly of skeletal muscle and attached to the hyoid bone, mandible and the styloid processes of the temporal bone.

	Tongue Cancer Answers
		Like the oral tongue, the base of tongue (or posterior 1/3) can also grow several types of cancers, but again, squamous cell carcinoma is the most common and we will direct our comments with that in mind.
		The tongue is actually divided into 2 separate anatomical areas, the oral tongue is the part you can "stick out" at somebody and extends backward to a V-shaped group of lumps on the back of the tongue which are actually specialized taste buds.
		The oral tongue and the base of the tongue comprise the whole tongue but it is important to know that they develop from different embryonic tissue and really are somewhat dissimilar.

	eMedicine - Hairy Tongue : Article by Denis Lynch, DDS, PhD
		The condition is limited to the posterior two thirds of the dorsal surface of the tongue.
		Hairy tongue clinically appears as an elongation of the filiform papillae on the dorsal surface of the tongue.
		The basic defect in hairy tongue is a hypertrophy of filiform papillae on the dorsal surface of the tongue, usually due to a lack of mechanical stimulation and debridement.

	The Voice & Swallowing Center
		While a functioning anterior two thirds of the tongue is critical to normal functioning of the oral phase of deglutition, the posterior one third of the tongue, or tongue base, also plays an important role in the generation of forces that propel a food bolus posteriorly towards the pharynx.
		Underscoring the importance of normal tongue mobility for normal deglutition to take place is the fact that any condition that affects the anterior two thirds of the tongue will necessarily affect the OPP and that any problems affecting the tongue base will alter the HSP.
		The primary action of the intrinsic muscles are to produce changes in the shape of the tongue during articulation and deglutition.
