- The taste buds of the tongue occur within papillae (foliate, fungiform, and vallate) present in the stratified squamous epithelium of the tongue. The taste buds consist of basal cells (near the basal lamina), supporting cells, and gustatory cells (sensory or neuroepithelial cells).The gustatory cells, which can be distinguished from supporting cells with a specific staining only, have microvilli at their apical ends extending in the taste pore.he 20X and 40X micrographs show in detail the layers of squamous stratified epithelium, the foliate papillae, and the taste bud. In the 40X micrograph the cells of the taste buds and its taste pore are visible. © 2004 Texas Histopages.

Epithelial Tissue Epithelial cells may be squamous, cuboidal, or columnar in shape and may be arranged in single or multiple layers. Simple cuboidal epithelium is found in glandular tissue and in the kidney tubules. Simple columnar epithelium lines the stomach and intestines.Pseudostratified columnar epithelium lines portions of the respiratory tract and some of the tubes of the male reproductive tract.hey form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

Types of papillae on tongue Taste buds contain the receptors for taste. They are located around the small structures on the upper surface of the tongue, soft palate, upper esophagus, the cheek, epiglottis, which are called papillae.he 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 tips of the taste cells reach toward a tiny opening on the tongue-the gustatory pore-through which food chemicals can fall. Nerve endings for the taste system and for the touch/temperature/pain system surround the base of the taste bud cells.

Smell & Taste These cells transmit messages to the brain, where specific smells or tastes are identified. 1  Olfactory (smell nerve) cells are stimulated by the odors around usthe fragrance from a rose, the smell of bread baking.  Gustatory (taste nerve) cells are clustered in the taste buds of the mouth and throat. They react to food or drink mixed with saliva. Many of the small bumps that can be seen on the tongue contain taste buds. These surface cells send taste information to nearby nerve fibers, which send messages to the brain.

Taste receptor The gustatory system consists of taste receptor cells in taste buds. Taste buds, in turn, are contained in structures called papillae. There are three types of papillae involved in taste: fungiform papillae, foliate papillae, and circumvallate papillae.(The fourth type-filiform papillae do not contain taste buds).bject A is a taste bud, object B is one taste cell of the taste bud, and object C is the neuron attached to the taste cell. I. Part I shows the reception of a molecule. 1. Sugar, the first messenger, binds to a protein receptor on the cell membrane.

GUSTATORY AND OLFACTORY SENSES Gustatory receptor cells are found in the taste buds of fungiform, foliate, and circumvallate papillae located mainly on the tongue. The distribution of the different papillae on the tongue is shown in Figure 10-1.he receptor cells are really bipolar nerve cells and therefore unlike the receptor cells of the eye, ear, and tongue which are specialized epithelial cells. The olfactory receptor cells have their nuclei in the lower 2/3 of the epithelium, but their apical ends project to the surface.

- Taste buds contain the receptors for taste. They are located around the small structures on the upper surface of the tongue, soft palate, upper esophagus, the cheek, epiglottis, which are called papillae.hese are located on top of the taste receptor cells that constitute the taste buds. The taste receptor cells send information detected by clusters of various receptors and ion channels to the gustatory areas of the brain via the seventh, ninth and tenth cranial nerves.

- Best Answer: sensory receptors. in mammals, the cells in the nose with these receptors are called olfactory cells, while in the tongue it is called taste receptor cells.taste receptor cells are clustered into what we know as taste buds.hope that helps. Source(s):or the tongue, it is more complicated. There are two types of receptors, the pressure sensitive receptors (general somatic afferent) and the chemical receptors (special sensory afferent). The chemical receptors which are located on your taste buds recognize 4 different tastes, sweet, sour, salty and bitter.

They are located around the small structures on the upper surface of the tongue, soft palate, upper esophagus, the cheek, epiglottis, which are called papillae.here are four types of lingual papillae present in the human tongue: 1  Fungiform papillae-as the name suggests, these are slightly mushroom-shaped if looked at in longitudinal section. 2  These are present mostly at the dorsal surface of the tongue, as well as at the sides. 3  Innervated by facial nerve.

Physiology of Taste The sense of taste is mediated by taste receptor cells which are bundled in clusters called taste buds. Taste receptor cells sample oral concentrations of a large number of small molecules and report a sensation of taste to centers in the brainstem.In most animals, including humans, taste buds are most prevalent on small pegs of epithelium on the tongue called papillae.he taste receptor cells within a bud are arranged such that their tips form a small taste pore, and through this pore extend microvilli from the taste cells. The microvilli of the taste cells bear taste receptors.

Simple cuboidal epithelium These cuboidal cells have large, spherical and central nuclei. Simple cuboidal epithelia are found on the surface of ovaries, the lining of nephrons, the walls of the renal tubules, and parts of the eye and thyroid.On these surfaces, the cells perform secretion and absorption.imple cuboidal cells are found in single rows with their spherical nuclei in the center of the cells and are directly attached to the basal surface. Simple ciliated cuboidal cells are also present in the respiratory bronchioles.

Taste Buds 3 terms. Most taste buds are located on the surface and the papillae of the tongue, but some are found in the oral cavity and pharynx. Pictured in slide 1 is a typical taste bud. Note the resemblance to a rose bud with the petal-like neuroepithelial cells NE arranged circularly within the bud.
