Impaired smell and taste impairs quality of life such as loss of food enjoyment, weight loss or weight gain, decreased appetite and safety concerns such as inability to smell smoke, gas, spoiled food and one’s body odor. Dysosmia and Dysgeusia are very unpleasant disorders that often accompany smell and taste impairments.

    Oral Cavity Histology Histology > Digestive System > Digestive System Oral Cavity LINGUAL PAPILLAE OF THE TONGUE Lingual papillae cover 2/3rds of its anterior surface; lingual tonsils cover its posterior surface. There are three types of lingual papillae: - Filiform, fungiform, and circumvallate; a 4th type, called foliate papillae, are rudimentary in humans. - Surface comprises stratified squamous epithelia - Core comprises lamina propria (connective tissue and vasculature) - Skeletal muscle lies deep to submucosa; skeletal muscle fibers run in multiple directions, allowing the tongue to move freely. - Taste buds lie within furrows or clefts between papillae; each taste bud comprises precursor, immature, and mature taste receptor cells and opens to the furrow via a taste pore. Distinguishing Features: Filiform papillae • Most numerous papillae • Their role is to provide a rough surface that aids in chewing via their keratinized, stratified squamous epithelia, which forms characteristic spikes. • They do not have taste buds. Fungiform papillae • "Fungi" refers to its rounded, mushroom-like surface, which is covered by stratified squamous epithelium. Circumvallate papillae • Are also rounded, but much larger and more bulbous. • On either side of the circumvallate papillae are wide clefts, aka, furrows or trenches; though not visible in our sample, serous Ebner's glands open into these spaces. DENTITION Comprise layers of calcified tissues surrounding a cavity that houses neurovascular structures. Key Features Regions 1 / 3 • The crown, which lies above the gums • The neck, the constricted area • The root, which lies within the alveoli (aka, sockets) of the jaw bones. • Pulp cavity lies in the center of the tooth, and extends into the root as the root canal.

Although it is a common condition that affects more than half of the population, few cases have been reported in the dermatological literature. Therefore, it is a condition uncommonly recognized by dermatologists though it has a distinct clinical presentation that may be easily diagnosed by clinicians familiar with the entity. We report an interesting case of transient lingual papillitis in a 27 year-old healthy woman following the consumption of the hard candy, Atomic Fireball.

    Tongue Anatomy 25/03/13 11:05 Medscape Reference Reference News Reference Education MEDLINE Tongue Anatomy Author: Eelam Aalia Adil, MD, MBA; Chief Editor: Arlen D Meyers, MD, MBA more... Updated: Jun 29, 2011 Overview The tongue is basically a mass of muscle that is almost completely covered by a mucous membrane. It occupies most of the oral cavity and oropharynx. It is known for its role in taste, but it also assists with mastication (chewing), deglutition (swallowing), articulation (speech), and oral cleaning. Five cranial nerves contribute to the complex innervation of this multifunctional organ. The embryologic origins of the tongue first appear at 4 weeks' gestation.[1] The body of the tongue forms from derivatives of the first branchial arch. This gives rise to 2 lateral lingual swellings and 1 median swelling (known as the tuberculum impar). The lateral lingual swellings slowly grow over the tuberculum impar and merge, forming the anterior two thirds of the tongue. Parts of the second, third, and fourth branchial arches give rise to the base of the tongue. Occipital somites give rise to myoblasts, which form the intrinsic tongue musculature. Gross Anatomy From anterior to posterior, the tongue has 3 surfaces: tip, body, and base. The tip is the highly mobile, pointed anterior portion of the tongue. Posterior to the tip lies the body of the tongue, which has dorsal (superior) and ventral (inferior) surfaces (see the image and the video below). Tongue, dorsal view. View of ventral (top) and dorsal (bottom) surfaces of tongue. On dorsal surface, taste buds (vallate papillae) are visible along junction of anterior two thirds and posterior one third of the tongue.

When transection occurs during neonatal development in the rat, the effects on fungiform taste bud and papillae structure are markedly more severe than observed following a comparable surgery in the adult rat.

The histological and ultrastructural analysis of the lingual papillae and lingual glands revealed the presence of two types of mechanical papillae, namely the filiform and conical papillae, while papillae with taste buds (including the fungiform papillae, vallate papillae, and foliate papillae) formed the second, less numerous group. The filiform papillae differed from those of Equidae or Rhinocerotidae. The presence of nine vallate papillae, localized in groups of two surrounded by a ring, or individually, was unique for the examined female tapir.

Ten adult Rock dove, (5 males and 5 females) were used in this study. Samples of the different regions of the tongue were routinel prepared for light and electron microscopic study. Results showed that the dorsal surface of the tongue is covered by a stratified squamous epithelium that is thicker in the dorsal surface than that of the ventral surface in the free portion of the tongue and is characterized by the presence of downward folds. The ventral epithelium that covers the free portion of the tongue is highly keratinized. The posterior of the free portion of the tongue ended by paired giant lingual wing. The dorsal surface of the lingual wing is smooth and carries one row of lingual papillae. The outer layers of the preglottal area are formed of squamous cells which is furnished by non-keratinized epithelium. The preglottal epithelium is characterized by the appearance of the dermal papillae.

Taste buds, which are clusters of neuroepithelial receptor cells, are housed in highly organized structures called taste papillae in the oral cavity. Whereas the overall structure of the taste periph- ery is conserved in almost all vertebrates examined to date, the anatomical, histological, and cell biological, as well as potentially the molecular details of taste buds in the oral cavity are diverse across species and even among individuals.

  • TONGUE DIAGNOSIS Introduction
    TONGUE DIAGNOSIS Introduction Tongue is generally known as the organ of taste. It also helps to articulate speech. The secondary functions of the tongue are to help swallowing and chewing the food. Tongue is made up of many muscles. The upper surface contains the taste buds that act as the primary organ of taste. The tongue's upper surface is also covered with numerous lingual papillae. Saliva keeps the tongue moist, which is necessary to keep it sensitive, and is abundantly supplied with nerves and blood vessels. The tongue also serves as a natural means of cleaning the teeth. The tongue is the only visible part of the digestive tract and therefore, considered as the mirror that reflects the conditions of the body's internal organs, particularly the organs of digestion and metabolism. The tongue also reflects the overall digestive, nutritive and metabolic conditions of the entire organism. It can prove to be a key factor in determining many conditions and the overall health of the body. Healthy tongue is free of any discomfort such as pain, stinging, burning, swelling or numbness. It is moist, with a rough surface and has an evenly coloured pink surface overlaying pale red. Greek physicians like Hippocrates and Galen considered different characteristics of the tongue to be an important indicator of health and diseases. Ayurveda, Unnai and Siddha systems have refined methods of tongue diagnosis. The Chinese medicine, considers tongue as a map that corresponds to different parts of the body. The tip is connected to the heart; the sides are connected to the liver; the centre to the spleen and the back to the kidney.
