Histology of the intestine
4 layers are mucosa, submucosa, muscularis, and serosa
Describe the tissue types found in each 4 layers and discuss their functions
Step by step
Solved in 5 steps
- On the histological preparation of the walls of the small intestine: there * are groups of cells at the bottom of the crypt, in the apical part of which there are large acidophilic secretory granules; the cytoplasm is basophilic. What are these cells? goblet cells. Columnar cell with a border. O Endocrine cells. Cells without border. Paneth cells.Histology of Large Intestine Walls Label the mucosa and submucosa of the large intestine wall by clicking and dragging the labels to the correct location. Lumen Mucosa with mucous glands Muscularis (circular and longitudinal layers) Submucosa Serosa O Victor P. Eroschenko Prav 18 of 20 Next >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 certain

- The small bowel biopsy results state, "flat mucosa with villus atrophy and hyperplastic crypts-inflammatory infiltrate in lamina propria." What do these results tell you about the change in the anatomy of the small intestine?Describe the role of these cells found in gastric glands: parietal, chief, mucous neck, and enteroendocrine.What is the importance of goblet cells in intestinal epithelium? Differentiate the types of exocrine glands based on the manner by which their glandular cells release their secretory glands. Name atleast 3 exocrine glands of the digestive system, give the organ where they are found and classify each gland according to morphology and number of secretory units. Tabulate your answer.
