What is shotgun histology?

Shotgun Histology is a series of YouTube videos that explain lab slides. The viewing time for all the videos amounts to 7 hours in total. The slides are manipulated and explained by the narrator. The slides are not labeled and the videos are not organized as a course.

What is the histology of the pancreas?

The pancreas is divided into lobules by connective tissue septae. Lobules are composed largely of grape-like clusters of exocrine cells called acini, which secrete digestive enzymes. Embedded within the pancreatic exocrine tissue are Islets of Langerhans, the endocrine component of the pancreas.

What is the pancreatic duct histology?

They have flattened cuboidal epithelium that extends up into the lumen of the acinus to form what are called centroacinar cells. The smaller forms have a cuboidal epithelium, while a columnar epithelium lines the larger ducts. Intralobular ducts transmit secretions from intralobular ducts to the major pancreatic duct.

What kind of tissue is in pancreas?

Almost all of the pancreas (95%) consists of exocrine tissue that produces pancreatic enzymes for digestion. The remaining tissue consists of endocrine cells called islets of Langerhans.

Where was the shotgun invented?

The earliest shotguns, or “Haile Shotte peics,” as they were called, date back to the 16th century in England, where they were used for hunting by the aristocracy, chief among them Henry VIII. These were multiple shot firearms and were used primarily for hunting birds.

What are pancreatic ducts?

The pancreatic duct, or duct of Wirsung (also, the major pancreatic duct due to the existence of an accessory pancreatic duct), is a duct joining the pancreas to the common bile duct. This supplies it with pancreatic juice from the exocrine pancreas, which aids in digestion.

Which type of epithelium is found in pancreatic duct?

All pancreatic ducts and the inter- lobular ducts were lined by simple columnar epithelium, with folds, while the ducts lumen was filled with secretory material.

What are the parts of shotgun ammunition?

The basic components of ammunition are the case, primer, powder, and projectile.

What is the structure of the pancreas at histological level?

At the histological level the pancreas is made up of compound glands in “bunch of grapes” fashion. The pancreas has an exocrine and endocrine component. The exocrine compnent is demonstrated above in 3D with acini in “cluster of grapes” formation subtended by a duct.

Where is the islet of Langerhans in the pancreas?

Normal histology of the pancreas showing the islet of Langerhans in the right lower corner of the image with the remaining glandular tissue being the exocrine portion of the gland. The islets only make up about 2% of the gland. A duct can be seen in the left lower quadrant surrounded by a thicklayer of connective tissue.

What is the exocrine component of the pancreas made up of?

The exocrine component of the pancreas makes up about 98% of the pancreatic tissue. It is comprised of densely packed serous acinar (tubuloacinar) glands. These glands are called pancreatic acini, which represent the secretory units of the pancreas. They are formed out of simple epithelium.

How do pancreatic secretions leave the acini?

Once synthesized, the pancreatic secretions leave the acini via the intercalated ducts. The latter are short ducts with a small lumen that start within the acini.
