Final - Digestive, Respiratory, Urinary Flashcards
What structure is this?
General tissue?
Specific?
esophagus
General tissue: nonkeratinized stratified squamous epithelium
Specific: esophageal tissue
B is specialized cell/gland
(see notes for answers)
What is this tissue?
esophagus
What gland is this?
General tissue?
Specific tissue?
What is P?
Stomach
General: Simple columnar epithelium with microvilli (and mucous neck cells)
Specific: stomach tissue
G: Gastric pits
What does the stomach look like?
Visualize
- PC- parietal cells (fluffy pink)
- N- gastric neck
- CC- chief cells (dark purple)
- MP- Meissner’s Plexus
MM- muscularis mucosa
BV- blood vessel
A- adipose cells
ME- muscularis externa
SMC- surface mucus cells
MNC- mucus neck cells
PC- parietal cells (fluffy pink)
N- gastric neck
CC- chief cells (dark purple)
GC- ganglion cells
SubM- submucosa
MP- Meissner’s Plexus
organ?
general tissue type?
specific?
Small Intestine
Gen: Simple columnar epithelium with microvilli made of enterocytes and goblet cells lines lumen (L)
Specific: intestinal tissue
what is this organ?
general tissue?
specific tissue?
what is special here?
Ilium
General: simple columnar epithelium with microvilli
Specific: intestinal tissue
Peyer’s patches: lymphatic nodules with visible germinal centers ONLY in ilium
Organ?
What is the blank spot that makes this organ special?
Duodenom
Brunner’s Glands: they can look like crypts, but crypts would be found above the submucosa and Brunner’s glands are in the submucosa. Secrete: alkaline mucous
What is the organ?
What is PC?
Plicae Ccirculares – transverse folds in intestinal lining
Villi (V) series of fingerlike projections in mucosa, covered by simple columnar epithelium
Microvilli projections off the villi, linked to the terminal web of cytoskeleton to form striated border
what is this organ?
what is special about it?
Colon
All that white is goblet cells lining the crypts.
Colon Mucosa does not have villi. It has crypts!! (arrows) which form tubular glands (GI)
Specialized cells/glands: goblet cells, paneth cells
What is this?
What does it secrete?
Sublingual Gland - acinar gland
each acinus drains into the smallest segment of the excretory duct system
what structure is this?
what 3 things make it different from another circular structure?
What is the blank white spot?
Appendix
Blank white: lymphatic nodules
Appendix is similar to colon but does not have: Teniae coli, Villi, Plicae Circulares
what is this organ?
pancreatic lobules separated by CT septa
what are these cells inside the pancreas?
Islets of Langerhans
what is this structure?
what makes it specialised? name the 2 spaces
(Palatine) Tonsil
Specialized:
- top space - tonsillar crypts
- bottom space - lymphatic nodules
what is this structure?
Liver
Remember: hepatic artery, hepatic portal vein, bile ducts (portal triad). Hepatic artery and Hepatic portal vein are easy to identify because they are found in relation to one another within the surrounding CT of the portal canal. Hepatic portal vein is typically thin walled, largest BV in portal triad. Hepatic artery is typically smaller with thicker wall. Typically appears as small diameter with thin layer of smooth muscle present in tunica media.
what is this structure?
Liver
BD- bile duct
CT- connective tissue
CV- central vein (terminal hepatic venule)
HA- hepatic artery
HV- hepatic portal vein
L- lymph nodule
PV- portal vein
what is this?
Trachea Mucosa
what is this?
Kidney
Cortical tissue is where you can see glomeruli (singular: glomerulus). Glomerular (Bowman’s capsule) is connected to initial segment of renal tubule and forms the outer wall of renal corpuscle and encapsulates glomerular capillaries.
RC- renal corpuscles
Arrows- medullary rays
what is the green “triangle” space plugging the hole?
what are the whitish lines?
what are they all called together?
- juxtaglomerular cells
- macula densa of DCT
- juxtaglomerular complex
