Large intestine. Liver. Pancreas

The mucous membrane of the large intestine differs from the mucous membrane of the small intestine:

• a lot of villi

• lack of villi

• fewer villi

• the presence of crypts

The epithelium of the colon mucosa differs from the epithelium of the small intestine:

• cell shape

• a large number of goblet cells

• lack of limb epithelial cells

• lack of borderless epithelial cells

The wall of the appendix is ​​characterized by:

• the presence of transitional epithelium in the mucous membrane

• the presence of a large accumulation of lymphoid tissue

• many crypts and villi

• lack of muscle

In the histological specimen, lobules and ducts of the pancreas are visible. The common duct of the gland is lined with epithelium:

• single-layer prismatic

• single layer flat

• multi-row

• multilayer non-keratinizing

On a histological specimen, the mucous membrane of the gallbladder is presented, this organ is lined with epithelium:

• multi-row ciliated

• transitional

• multilayered with signs of keratinization

• single-layer prismatic fringed

Intramural parasympathetic nerve ganglia in the colon wall are located in:

• muscular layer

• adventitia

• mucous membrane

• submucosa

The micrograph shows the acinus of the pancreas. The secretory cells (3.1) in the pancreas are:

• acinocytes

• insulocytes

• myoepithelial cells

• centroacinous

The micrograph shows the acinus of the pancreas. The composition of the pancreatic acinus includes:

• exocrine pancreatocytes

• insulocytes

• intermediate cells

• centroacinous cells

The structure on the histological preparation of the organ parenchyma is represented by lobules, which are shaped like hexagonal prisms and consist of anastomosing beams, between which lie sinusoidal capillaries that radially converge to the central vein. What anatomical organ has this morphological structure?

• Liver 

• Pancreas

• Thymus 

• Spleen

The patient is observed by an endocrinologist about a violation of the endocrine function of the pancreas, which is manifested by a decrease in the amount of the hormone glucagon in the blood. In this case, the function of the Langerhans islet cells is impaired.
