The wall of the stomach is composed of a mucosa, submucosa, muscularis and serosa. Tunica mucosa consists of- Surface epithelium, The glandular lamina propria, and Muscularis mucosae Mucosa Surface epithelium It begins abruptly at the jagged border of stratified squamous epithelium of the oesophageal mucosa. It consists of a single layer of high columnar cells. […]
The wall of the fore stomach consists of a non-glandular mucous membrane, a two-layered muscular tunic, and a serosa. Rumen The mucosa forms large tongue shaped or conical papillae. The mucosa has neither gland nor lymph nodules. The stratified squamous epithelium is of the cornifying type and the stratum corneum forms relatively thick layer on
The wall of the stomach consists of a mucosa, submucosa, muscularis and serosa tunics. The true gastric mucosa is characterized by the presence of gastric glands. Only the stomach of man and carnivores are lined by gastric mucosa exclusively. In solipeds and swine the oesophageal portion of the stomach bears a cutaneous mucosa (stratified squamous
The wall of Oesophagus consists of a mucous membrane lined by stratified squamous epithelium and a muscular coat, which in the cervical region is covered by a loose fibrous adventitia. In the thoracic region, the latter is replaced by a serous membrane. Mucosa It is lined by stratified squamous epithelium and is thrown into longitudinal
The digestive tube is lined internally by a continuous mucous membrane, which begins at the mouth and ends at the anus. Beginning with the Oesophagus, the alimentary canal has a wall made up of four layers or tunics, which have some common general, features and specific regional characteristics. The four coats are from within outwards.
Taste buds are microscopic structures found in the epithelium of the fungiform, foliate and circumvallate papillae of the tongue; they are also found widely separated in the soft palate; epiglottis and the free edge of the vocal folds. They are ellipsoid bodies embedded in an upright position in the epithelium of the mucous membrane. The
Tongue organ consists essentially of a lining of stratified squamous epithelium and striated muscle, arranged in a number of layers. The connective tissue attaches the tough mucous membrane of the tongue to the muscular mass. The epithelium of the tongue is thickest and has the heaviest stratum corneum on the dorsal surface. The tongue bears
The Salivary glands may be classified on the basis of their secretion and the epithelium of their end-pieces as serous, mucous and mixed glands. Of the three pairs of salivary glands in mammals, the parotid glands is the serous type, the mandibular and sublingual glands are of the mixed type. The salivary glands are true
The digestive system consists of the alimentary tract and other associated structures like the tongue, teeth, salivary gland, liver and pancreas. In Histology of Digestive system, these given headings will be discussed in detail- Salivary glands Tongue Taste buds Digestive tube Oesophagus Stomach Forestomach of ruminants Glandular stomach Small intestine Large intestine Blood vessels to
Besides the blood vessels, the body contains a collateral system of channels, lined by endothelium which collect the tissue fluid and return into the blood stream. The fluid in these vessels is lymph. Unlike blood, the lymph circulates in one direction only, from the periphery towards the heart. The lymphatic capillaries starts blindly from the
