What are the papillae on the tongue?
Lingual papillae are little elevations of the tongue surface. Some have taste buds and some don’t. There are four kinds of papillae on the human tongue: 1 Fungiform papillae. Fungiform means “mushroom-shaped.” These are widely distributed across the tongue, but are especially numerous at the tip and along the margins (all those in figure 1 are fungiform). They’re shaped like mushroom caps or round footstools. Each one has two or three taste buds at its apical surface. 2 Foliate papillae. Foliate means “leaflike.” These are parallel ridges along the sides of the tongue (fig. 4), at the rear near the molar teeth. Foliate papillae have taste buds on their lateral surfaces, opening into the trenches between them. They’re rather weakly developed in humans compared to other mammals, found mostly in young children, and largely disappear after age 2 or 3. They’re well positioned, though, to immediately sense tastants liberated from the food by chewing, and I suspect they might be part of the reason toddlers are more fussy eaters than adults. It would be adaptive to reject and spit out bad-tasting items at such a young age when the brain is rapidly developing and especially vulnerable to toxins.
Why do I have red bumps on my tongue?
Little red bumps on the tip of the tongue is a sign of inflammation of your taste buds, taste buds at the tip of your tongue is known clinically as filiform papillae, they do not contribute to taste but rather the texture of the tongue, giving the tongue a cleaning and rasping action.
What are taste cells?
Taste cells are somewhat banana-shaped. Supporting cells are more flattened, shaped like curved barrel staves, and mostly form a surrounding capsule around the perimeter of the taste bud. Taste cells are epithelial cells, not neurons, but they have neuron-like synaptic vesicles at the base.

What are the taste buds on the tongue?
The taste buds on the tongue sit on raised protrusions of the tongue surface called papillae. There are four types of lingual papillae; all except one contain taste buds: 1 Fungiform papillae - as the name suggests, these are slightly mushroom -shaped if looked at in longitudinal section. These are present mostly at the dorsal surface of the tongue, as well as at the sides. Innervated by facial nerve. 2 Foliate papillae - these are ridges and grooves towards the posterior part of the tongue found at the lateral borders. Innervated by facial nerve (anterior papillae) and glossopharyngeal nerve (posterior papillae). 3 Circumvallate papillae - there are only about 10 to 14 of these papillae on most people, and they are present at the back of the oral part of the tongue. They are arranged in a circular-shaped row just in front of the sulcus terminalis of the tongue. They are associated with ducts of Von Ebner's glands, and are innervated by the glossopharyngeal nerve. 4 Filiform papillae - the most numerous type but do not contain taste buds. They are characterized by increased keratinisation and are involved in the mechanical aspect of providing abrasion.

What are the two types of cells that make up the taste buds?
The bud is formed by two kinds of cells: supporting cells and gustatory cells . The supporting ( sustentacular cells) are mostly arranged like the staves of a cask, and form an outer envelope for the bud. Some, however, are found in the interior of the bud between the gustatory cells. The gustatory (taste) cells, which are chemoreceptors, occupy the central portion of the bud; they are spindle-shaped, and each possesses a large spherical nucleus near the middle of the cell. The peripheral end of the cell terminates at the gustatory pore in a fine hair filament, the gustatory hair. The central process passes toward the deep extremity of the bud, and there ends in single or bifurcated varicosities. The nerve fibrils after losing their medullary sheaths enter the taste bud, and end in fine extremities between the gustatory cells; other nerve fibrils ramify between the supporting cells and terminate in fine extremities; these, however, are believed to be nerves of ordinary sensation and not gustatory.
Which type of papillae do not contain taste buds?

The gustatory (taste) cells, which are chemoreceptors, occupy the central portion of the bud; they are spindle-shaped, and each possesses a large spherical nucleus near the middle of the cell.

What is the primary organ of taste?
The tongue is a muscular organ in the mouth of a typical vertebrate. It manipulates food for mastication and swallowing as part of the digestive process, and is the primary organ of taste. The tongue's upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae.
Which nerve is responsible for taste perception?
The pharyngeal part is supplied by the glossopharyngeal nerve and the oral part is supplied by the lingual nerve (a branch of the mandibular branch (V3) of the trigeminal nerve) for somatosensory perception and by the chorda tympani (a branch of the facial nerve) for taste perception . Both parts of the tongue develop from different pharyngeal ...
What is the groove on the left side of the tongue?
The left and right sides are also separated along most of its length by a vertical section of fibrous tissue (the lingual septum) that results in a groove, the median sulcus, on the tongue's surface. There are two groups of muscles of the tongue. The four intrinsic muscles alter the shape of the tongue and are not attached to bone.
What is the function of the tongue?
The tongue also serves as a natural means of cleaning the teeth. A major function of the tongue is the enabling of speech in humans and vocalization in other animals. The human tongue is divided into two parts, an oral part at the front and a pharyngeal part at the back.
How many muscles are there in the tongue?
The eight muscles of the human tongue are classified as either intrinsic or extrinsic. The four intrinsic muscles act to change the shape of the tongue, and are not attached to any bone. The four extrinsic muscles act to change the position of the tongue, and are anchored to bone.
Why is the tongue important?
The tongue is used for crushing food against the hard palate, during mastication and manipulation of food for softening prior to swallowing . The epithelium on the tongue's upper, or dorsal surface is keratinised. Consequently, the tongue can grind against the hard palate without being itself damaged or irritated.
