The dorsum of the tongue is covered by a stratified squamous keratinized epithelium with filiform, fungiform, and circumvallate (not seen here) papillae. The ventral surface of the tongue is covered by a stratified squamous moist epithelium (lining mucosa) In histology of tongue, you will find stratified squamous epithelium on the mucosa of animal tongue. You know, it is keratinized and thick at dorsal part of the tongue and non-keratinized, thin at ventral part of the tongue. The dorsal surface of tongue have numerous projection like structure called papillae Deep to the ventral muscles is the layer of transverse muscles of the tongue. They take a lateral route, extending from either side of the medial lingual septum (origin) to the fibrous submucosa along the lateral margins of the tongue (insertion). As these muscles contract, they cause the tongue to narrow and elongate
In slide 116, the dorsal surface of the tongue is covered with tiny projections called papillae View Image, which are lacking on the ventral surface. The body of the tongue is composed of interlacing bundles of skeletal muscle View Image that cross one another at right angles. The dense lamina propria of the mucosa is continuous with the.

HISTOLOGY OF THE TONGUE AND SALIVARY GLAND ODERINDE, Gbenga Peter 2. TONGUE Introduction • The tongue lies on the floor of the oral cavity, it is attached to the floor of the oral cavity posteriorly • It has a dorsal surface that is free; and a ventral surface that is free anteriorly (Singh 2011) Midline fold of tissue between ventral surface of tongue and floor of the mouth Lingual papillae Small elevated structures of specialized mucosa on the tongue Lingual Tonsils Irregular mass of tonsillar tissue located posteriorly on the dorsal surface of the tongue Circumvallate papillae Larger mushroom shaped lingual papillae that line up. 3 Describe the Features of Ventral Surface of Tongue. 4 Describe the Features of Dorsal Surface of Tongue. 5 What are the Types of Lingual Papillae? 6 Describe Origin, Insertion, Action and Nerve Supply of Tongue. 7 Describe the Sensory Nerve of Tongue and Correlate it with It's Development. 8 Describe Blood Supply of Tongue
The following emerged from the primary trunk(s): thin branches for the ipsilateral mucosa of the ventral surface of the tongue and 4-9 thick secondary trunks, with palisade disposition and translingual courses that followed the outer surface of the genioglossus muscle towards the dorsal mucosa of the ipsilateral part of the tongue, anterior to. Ventral Surface of Tongue • Ventral or undersurface of the tongue is shiny, and blood vessels are visible • Lingual frenum - thin sheet of tissue at the midline that attaches the undersurface of the tongue to the floor of the mouth • Sublingual papilla - A swelling on both sides of the lingual frenulum at the tongue base - Marks the. Nonkeratinized squamous epithelium covers the soft palate, inner lips, inner cheeks, and the floor of the mouth, and ventral surface of the tongue. Keratinized squamous epithelium is present in the gingiva and hard palate as well as areas of the dorsal surface of the tongue White lesion (leukoplakia) involving left lateral border of tongue (ellipse) which proved on histology as hairy leukoplakia. Biopsy site marked as (+). Retroviral disease needs to be ruled out. Multiple small size ulcers involving ventral surface of tongue (arrows). Multiple larger size ulcers involving ventral surface of tongue
Minor salivary glands (labial glands) are located in the submucosa beneath the lamina propria. The minor salivary glands produce both serous and mucous secretions. Mucosal epithelium also lines the cheeks, floor of the mouth and the ventral surface of the tongue. 10x, 100 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.It is sensitive and kept moist by saliva and is richly supplied with nerves and blood vessels Abstract The epithelium of the ventral surface of the apex of the tongue in most birds is specified by the presence of the special superficial layer called lingual nail In the body cylindrical papillae with a flat surface are present, aborally gradually substituted by imbricated papillae. Foliate-like papillae were observed in the lateral parts of the tongue body. No sensory structures were showed on the lingual dorsal surface, while they were numerous in the oral cavity, particularly on the gingival epithelium
The ventral surface of lingual apex was divided into two portions by the U-shaped fungiform line into papillary and non-papillary region. Histological investigation on the lingual surface epithelium and lamina propria submucosa reflects differences in these layers in different parts of the tongue ducts open on to the ventral surface. Glands of Von Ebner: • Purely serous glands located in circumvallate papillae and their ducts open into the grooves of circumvallate papillae. Mucous glands of the root: • Purely mucous glands lie in the posterior one third of the tongue and their ducts open into the crypts of lingual tonsil Upon examination, a well-demarcated, dome-shaped, smooth-surfaced, exophytic, pink to focally gray nodule was identified on the ventral surface of the tongue (Figure 1). The lesion was firm to palpation but was not painful, and there was no evidence of calcification associated with the lesion. Figure 1. Clinical photograph taken at the first visit

It reflects up onto the ventral surface of the tongue above (A).Note the glands (B) and fat cells in the submucosa of the floor of the mouth.The height of the connective tissue papillae in this region is also relatively low The papillae are separated from the surface of the tongue with a 'V' shaped sulcus located around the papillae. Coming to the Histology, it is lined by keratinized stratified squamous epithelium at the superficial surface and non-keratinized epithelium on the lateral surface, taste buds are seen on this lateral surface Texture: The tongue should have a rough dorsal surface due to papillae (taste buds). There should be no hairs, furrows, or ulceration. The ventral side of the tongue should have a smooth surface. Size: The tongue should fit comfortably in the mouth with the tip against the lower incisors. The sublingual glands should not be displaced

In this cross-section through the tongue of a newborn infant, can you identify fungiform (A) and filiform (B) papillae of its dorsal surface? On either side of the midline in the lower half of the tongue are two masses of bracketed glandular tissue. These are the anterior lingual glands (C). They secrete onto the ventral surface of the tongue The tongue showed three modes of tongue flicking: simple downward extension, single oscillation, and multiple oscillations. At each tongue flick, the ventral surface of the tips was observed contacting the substratum.

The ventral surface of the tongue is smooth and is covered by thin non-keratinized stratified squamous epithelium continuous with that of the floor of the mouth. The dorsal surface is covered by stratified squamous keratinized epithelium and is raised into a series of elevations called lingual papillae The dorsal surface of tongue is very rarely involved. Usually, SCC of the posterior tongue is more aggressive than that of the anterior tongue. Around 78% of base of tongue SCCs show early metastasis, especially to regional lymph nodes; in this group about 69% of tongue carci-nomas show evidence of metastasis at admission This is a healthy four-year-old girl whose mother was the first to notice a single, smooth-surfaced, well-demarcated and grayish-pink nodule on the right side of the ventral surface of tongue about 4 X 4 mm in size.

On the ventral surface of the tongue, there is the deep lingual vein that joins the sublingual vein coming from the sublingual salivary gland. Fig. 1: Human Tongue and its Parts. Tongue Definition: You can define the tongue in several ways. For example, The Free Online Dictionary defines it as The lower surface of the tongue is smooth, with typical lining mucosa. The dorsal surface is irregular, having hundreds of small protruding papillae of various types on its anterior two-thirds and the massed lingual tonsils on the posterior third, or root of the tongue (Figure (a)) Moreover, round fungiform papillae were more numerous on the lateral surface of the apex and body of the tongue (they were large close to the ventral surface of the apex) (Figure 1B). Nine vallate papillae located in a semicircle between the body and root of the tongue were also distinguished ( Figure 1 A) DISCONTINUED SITE-SPECIFIC FACTORS: SSF7, SSF8, SSF10; C02.0 Dorsal surface of tongue, NOS; C02.1 Border of tongue (Tip) C02.2 Ventral surface of tongue, NO tongue showed mucous acini in pharyngeal part (Fig. 3).

The tongue's embryonic orgin is derived from all pharyngeal arches contributing different components. As the tongue (Latin, lingua; Greek, glossa) develops inside the floor of the oral cavity, it is not readily visible in the external views of the embryonic (Carnegie) stages of development.Tongue muscle cells originate from somites mesoderm, while muscles of mastication derive from the. Tongue is formed of a mass of muscles and salivary gland embedded in anterior highly vascular and posterior lymphoid stroma and covered by specialized surface epithelium.

6 Special Senses . The human body experiences its environment by reacting to stimuli that reach the brain via the nervous system. The somatic or general senses, including touch, temperature perception, pain, and proprioception (the awareness of one's position and movement in space), use the free nerve endings in the skin, muscles, and membranes of the body to detect change and communicate. The need for early extraction in the presence of two risk factors is highlighted in this case report.
