What is shotgun histology?

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 histology of Oesophagus?

The epithelium, lamina propria, and muscularis mucosa. The thick epithelial layer lines the lumen of the esophagus and consists of stratified squamous non-keratinized cells, which has their typical appearance of flat, overlapping cells that are more flat as they move away from the base or basal cell layer.

What are the 4 layers of the Oesophagus?

Structurally, the esophageal wall is composed of four layers: innermost mucosa, submucosa, muscularis propria, and adventitia. Unlike the remainder of the GI tract, the esophagus has no serosa. On endoscopy, the esophageal lumen appears as a smooth, pale pink tube with visible submucosal blood vessels.

What epithelium is in Oesophagus?

Squamous epithelium, seen in the esophagus and skin, consists of layers of flat cells. Columnar epithelium, characteristic of the rest of the gut, consists of a single layer of tall, rectangular cells.

What is histology of liver?

The liver is a mixed gland surrounded by a thin capsule of connective tissue, the Glisson capsule, dividing the parenchyma into lobules and lobuli. The histological unity of the liver is composed of the liver lobuli, with classic, portal and acini conceptions.

What is histology of kidney?

The kidneys have a tough fibrous capsule (irregular dense connective tissue) for protection. Otherwise they have very little connective tissue between the nephrons. The kidney has a granular cortex (outer region). This is an H&E stained section of kidney -showing the cortex and the medulla.

What type of cells are in the esophagus?

It has 3 parts:

• The epithelium is the innermost lining of the esophagus and is normally made up of flat, thin cells called squamous cells.
• The lamina propria is a thin layer of connective tissue right under the epithelium.
• The muscularis mucosa is a very thin layer of muscle under the lamina propria.

What are the two muscles present in Oesophagus?

The muscular layer of the esophagus has two types of muscle. The upper third of the esophagus contains striated muscle, the lower third contains smooth muscle, and the middle third contains a mixture of both.

How long is the human Oesophagus?

about 8 inches long
The esophagus is about 8 inches long, and is lined by moist pink tissue called mucosa. The esophagus runs behind the windpipe (trachea) and heart, and in front of the spine. Just before entering the stomach, the esophagus passes through the diaphragm.

Is esophagus on right or left?

Esophagus is located at left of midline at level of 1st dorsal vertebra, right of midline at level of 6th dorsal vertebra, and left of midline again at level of 10th dorsal vertebra. Thus, esophagus makes a reverse “S” all the way in front of vertebral column.

Which is the function of the oesophagus?

Oesophagus 1 Function of the Oesophagus. The oesophagus is a muscular tube through which food is carried from the pharynx to the stomach. 2 Layers of the Oesophagus. 3 Oesophageal Epithelium. 4 Oesophogeal Mucosa. 5 Other layers of the Oesophagus.

What are the layers of esophagus and histology?

Which is the transverse section of the oesophagus?

This photograph shows a a transverse section of the oesophagus at low power, so you can see almost all of the whole oesophagus, including its four layers: – mucosa, submucosa, muscularis externa, and adventitia.

Where is the sphincter located in the oesophagus?

At the junction with the stomach (oesophago-gastic junction), there is a sphincter, which usually prevents reflux or regurgitation. This photograph shows a a transverse section of the oesophagus at low power, so you can see almost all of the whole oesophagus, including its four layers: – mucosa, submucosa, muscularis externa, and adventitia.
