Step by step
Solved in 2 steps
- All the structures of the alimentary canal have 4 similar major histological tissues . Which of the following descriptions of the tissue layers contains innacurate information? A) The mucosa layer consits of a simple epithelium (responsible for absoprtion), a lamina proprioa (supports the epithelium) and muscularis mucosae (thats ivolved with peristalsis. B) The muscularis externa has 2 or 3 layers of smooth msulce and is involced with persistalsis C) The submucosa layer is a connective tissue layer that anchors the mucosa layer and contains many blood vessels, lyphatic vessels, and nerves D) The serosa layer is a connective tissue layer that tethers the alimnetary canal to the appropirate body cavitities. I believe that D is false but I am not certainOn the histologic section of the glands stomach's fundus, relatively large electron-microscopically cells with acidophilic cytoplasm can be seen, and in these cells there is a complicated system of intracellular tubules. What component of gastric juice is formed due to the activity of these cells? Serotonin Mucus Gastrin O Hydrochloric acid Opepsinogen20 years old patient is prescribed long-term treatment of aspirin in the reason of rheumatism. What structural component of the stomach mucou membrane will be most ensuring its protection against damage? non keratinized stratified squamous epithelium O Muscle tissue O Simple columnar glandular epithelium O Pseudostratified epithelium O Connective tissue

What are these cells? goblet cells. Columnar cell with a border. O Endocrine cells. Cells without border. Paneth cells.A histological specimen of submandibular salivary gland represents basket * cells from which some processes radiate and embrace the secretory unit. Contraction of the processes of these cells helps in expelling secretions from the lumen of secretory units and moving them to the system of excretory ducts. Name these cells: Serous cells O Mucocytes Epithelial cells O Adipocytes O Myoepithelial Cells

It picks up cholesterol from extra-hepatic tissues and brings it back to the liver. It acts as a cholesterol store for tissues that need cholesterol to function.The pancreases secretes insulin which is made up of chain of 51 amino acids. How is insulin able to enter the bloodstream despite its relatively large size? 1. The pancreas contains continuous capillatries. 2. The pancreas contains cell that are very good at exocytosic which creastes a larher concentration of isulin in the interstitial fluid that diffuses into the blood. 3. The pansrea contains fenestrated cappilaries. 4. Insullin is hydropholic so it can diffuse across cell membranesThe effect of some harmful factors caused focal damage to the gastric epithelium.
