Step by step
Solved in 2 steps
- Describe the role of these cells found in gastric glands: parietal, chief, mucous neck, and enteroendocrine.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 certainA 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
