Pictures of B3; W1 Flashcards
Describe the different components of the pyruvate dehydrogenase complex & how they all fit together.
The core is a pentagonal dodecahedron, made up of 20 trimers.
E1 is arranged around the core & touches the lipoyl domain of E2.
E3 subunits are also in the core.
What structure is this? What does it require to function? What is it a part of? What does it help make?
TPP
requires Vitamin B1: Thiamine to function
a part of pyruvate dehydrogenase complex
eventually helps make acetyl CoA from pyruvate
Which cofactor does this show? Attached to which enzyme? A part of which complex? What is the end product?
Lipoamide
E2/DLTA (dihydrolipoyl transacetylase)
pyruvate dehydrogenase complex
pyruvate–>acetyl CoA
What structure is this? What does it help activate? What complex are we talking about?
Coenzyme A
DLTA
dihydrolipoyl transacetylase
pyruvate dehydrogenase complex
Just a summary slide. Do you understand everything on here?
AHHH not yet!!

No! I don’t-hopefully soon, though.

What structure is this? Hint: found in the tongue…
What is its function? Is it abundant?
Fungiform Papillae
Located on the margin of the tongue…contains taste buds. 2nd most abundant type of papillae on the human tongue.
Identify this structure. Hint…found in the tongue. What is its function? Where is it located? Is it abundant?
Filiform papillae
located on the dorsum of the tongue
most abundant papillae on the human adult tongue
doesn’t have taste buds, but is meant for creating friction b/w the tongue & the food…scraping!!
Identify these structures.
It’s labeled…but does it make sense?? : )
Label these structures. What is the entire thing called?
Circumvallate papillae
Picture in your head circumvallate & foliate & fungiform papillae & where they are located on the tongue…also…what their shape looks like.
Are you comfortable identifying the things on this picture?
Good luck!! You can do it : )
What is this? What are the arrows pointing to?
What is this? What are the arrows pointing to?
What is this structure? What are the arrows point to?
What is this? What do those cells there secrete?
Diffuse Lymphatic Tissue
plasma cells secreting IgA…
What is the name of the area that is outlined?
Superficial Inguinal Ring
**until the spermatic cord exits the superficial ring it isn’t really a spermatic cord…
Identify the structures indicated.
What are these structures?
Which types of hernias correspond to each location?
Yellow triangle–>direct
Green Circle–>Indirect
Identify these structures.
What is the red lining?
What are the 2 red balls at the top? What will they become?
Red lining is the peritoneal lining. Outside; parietal; Inside; visceral
Intermediate Mesoderm–>urogenital system
The left pic is most likely in the ____ region b/c of the presence of the ____. This means that the dorsal mesentery is _____. However, in the right pic…the dorsal mesentery is ____ b/c there is no _____.
The left pic is most likely in the foregut b/c of the ventral mesentery. This means that the dorsal mesentery is discontinuous. However, in the right pic the dorsal mesentery is continuous b/c there is no ventral mesentery.
What takes place from the left pic to the right pic?
Where is the left coelomic sac? Right coelomic sac? What connects the 2?
The completion of the midgut rotation inside the abdominal cavity around the 10th week.
Note that the cecum was in the upper right quadrant. Then it gets rotated into the lower left quadrant.
Left coelomic sac is pretty much everything you are looking at. The right coelomic sac is the purple sac behind it.
The epiploic foramen connects the 2 sacs.
What does this picture show?
volvulus of diverticulum
the thing on the right is the umbilical sinus
What condition is shown here?
Gastroschisis
What condition is shown here?
Omphalocele
Which hernia is direct? Which hernia is indirect?
