Ventral surface of tongue histology

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.

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

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.
