1. Where can blood drain to superiorly and inferiorly from the esophagus?
2. What part of the GI tract has no goblet cells? |
1. superiorly to azygous system
inferiorly to portal system 2. stomach |
|
|
what are the four gross anatomy regions of the stomach?
Histologically which two regions are same? |
Histologically fundus and body are same
1. Cardia • Narrow, collar‐like region at gastroesophageal junction (2‐3 cm wide) 2. Fundus • Dome‐shaped region to left of esophagus • Frequently filled with gas 3. Body (corpus) • Fundus and body are histologically identical • Largest region • Responsible for chyme production 4. Pylorus (l., Gate‐keeper) • Funnel‐shaped • Pyloric sphincter |
|
|
Main two criteria to distinguish three
histological regions of stomach: |
1. Gastric glands- Named according to their location in stomach• Cardiac glands• Fundic glands • Pyloric glands
2. Gastric pits- Epithelial invaginations into mucosa that increase surface area – Shallow to deep |
|
|
quickly name the four layers of the stomach (histologically)
|
1. Mucosa
2. SUBMUCOSA‐ Sm 3. Muscularis externa‐ME 4. Serosa (arrow) |
|
|
What are the type of stomach mucosa (6)?
|
1. Surface mucous cells
2. Undifferentiated (stem) cells 3. Mucous neck cells 4. Parietal (oxyntic) cells 5. Chief (zymogenic) cells 6. Enteroendocrine cells |
|
|
Produce low-molecular-weight • Secrete hormone‐like substances in the enteric (g., Bowels, relating to intestines) canal low molecular polypeptides
|
(gastro)ENTEROENDOCRINE CELLS
|
|
|
Rugae is?
|
– Mucosa & submucosa
– Irregular temporary folds when stomach is empty |
|
|
1. what is unique concerning the histology of the esophagus?
2. • what is the distinguishing feature of the fundic (body of the) stomach? |
1. – str. Sq epi, Glands in the submucosa, ME has skeletal and smooth muscle–
2. short pits, lots of parietal and chief cells |
|
|
• what is diagnostic for the cardiac stomach?
|
– shallow pits, lots of mucous cells, coiled glands
|
|
|
• what is diagnostic of the pyloric stomach?
|
– Deep‐med pits (may be coiled) and short glands
|
|
|
• what is unique concerning the histology of the stomach?
|
– ME has 3 poorly defined muscular layers
|
|
|
esophagus notice
ME- muscularis externa SM- submucosa MM- muscularis mucosa LP- lamina propria |
|
What does this line separate and what is it a general picture of?
|
Esophagus separates cardiac area
|
|
What does line indicate and what is slide of?
|
gastrointesophageal junction line indicates where it becomes cardiac esophagus
|
|
|
|
|
What is this a slide of and what are the 6 types of cells in it?
|
Stomach Mucosa
1. Surface mucous cells 2. Undifferentiated (stem) cells 3. Mucous neck cells 4. Parietal (oxyntic) cells 5. Chief (zymogenic) cells 6. Enteroendocrine cells |
|
What type of stomach mucosa cells are these?
|
5. Chief (zymogenic) cells
|
|
What type of stomach mucosa pit or gland is this?
What type of gland and how did yo know? |
know that it is cardiac due to coiled bases, wide lumen, predominant mucous cells
|
|
What is this showing and what subtype and how do you know?
|
stomach mucosa: Undifferentiated (stem cell)
- oval nuclei |
|
What part of body does this show and what subtype is it?
What is the role of subtype? |
Stomach mucosa:
MUCOUS NECK CELLS (Mn)- role in reducing friction by secreting soluble acidic mucus that mixes with and lubricates chyme notice pale stain, irregular shape, nucleus on base, granules at apex |
|
type of stomach mucosa and role
|
parietal (large and round "boobs", central nuclei, secrete H+ and Cl-, gastric intrinsic factor for B12, control cholinergic stimulation
|
|
What is this?
What does it contain and composed of? |
submucosa (Sm) of stomach
composed- of DICT Contains- blood and lymph vessels, lymphocytes, macrophages, mast cells |
|
What is this and what are colors (left to right)?
|
Layers of stomach wall
1. Black -Mucosa, muscularis mucosa, 2. Blue - SUBMUCOSA‐ Sm 3. Red- Muscularis externa‐ME 4. Green -Serosa (arrow) |
|
what problem do we see in this stomach slide?
|
H.pylori
|
|
Just from the picture's written description and your amazing brain what are we seeing here?
|
pyloric gastric glands
|
|
Just from the description on the pic what are we seeing?
|
Gastric gland known as fundic gland, long with lots of chief cells
|
|
This is a great picture for general knowledge what are you looking at and lable
|
lower 1/3 esophagus
|
|
|
fundic glands
|
|
Label parts and explain where this is...
|
Esophagus upper part (due to skeletal muscle)
|
