Flashcards in GI Histology LC Deck (12):
1

In this image, identify the deepest component of the mucosa!

Q image thumb

The mucosa of the colon includes epithelium, lamina propria and the muscularis mucosa (deepest part).

2

Which of the following segments of the tubal GI tract is mostly devoid of serosa?

Esophagus

Stomach

Duodenum

Jejunum

Ileum

Cecum

ESOPHAGUS

Only the distal 1 to 2 cm of the esophagus, in the peritoneal cavity, is covered by serosa; the rest is covered by the loose connective tssue of the adventitia which belnds into the surrounding tissue.

Only the distal 1 to 2 cm of the esophagus, in the peritoneal cavity, is covered by serosa; the rest is covered by the loose connective tssue of the adventitia which belnds into the surrounding tissue.

Q image thumb

The submucosa of the esophagus contains small mucus-secreting glands which lubricate and protect the mucosa.

5

In this image, the likely source of this neoplasm is

Glandular Epithelium

Squamous Epithelium

Vascular Epithelium

Q image thumb

GLANDULAR EPITHELIUM

The neoplastic cells are forming glands/lumens.

6

In this image, the likely source of this neoplasm is 

Glandular Epithelium

Squamous Epithelium

Vascular Epithelium

Q image thumb

SQUAMOUS EPITHELIUM

The neoplastic cells are in sheets and producing keratin

7

This mucosa is most likely from what part of the digestive tract?

Esophagus

Stomach

Small Intestine

Large Intestine

Rectum

Q image thumb

SMALL INTESTINE 

The presence of villi and goblet cells strongly suggests small intestine.

8

What histological features in this image favor large intestine over small intestine?

Muscularis Propria

Vessels in the submucosa

Lack of villi

Presence of Goblet cells

Lack of muscularis mucosa

Q image thumb

LACK OF VILLI

The large intestine does not have villi.

9

The main function of these cells is

Production of Bile

Production of RBCs

Storage of Bile

Storage of RBCS

Q image thumb

PRODUCTION OF BILE

These are hepatocytes (liver cells).

10

In this pancreas, identify the Islet of Langerhans!

Q image thumb

Islet of langerhans is the source of endocrine function of the pancreas.

11

In this pancreas, identify the source of digestive enzyme!

Q image thumb

Digestive enzymes are produced by cells of the serous acini.

12

This epithelium is best described as

Stratified Epithelium

Pseudostratified Epithelium

Transitional Epithelium

Q image thumb

PSEUDOSTRATIFIED

Dysplastic colonic epithelium.
