Final Exam Flashcards
what organ is this?
(and context for next slide)
colon (large intestine)
what structure is this tissue part of (outlined)?
meissner’s plexus (colon)
(above it: inner circular
below it: outer longitudinal)
what are these structures inside dotted line?
alveoli sac
blue dotted line?
yellow?
blue: bronchiole
yellow: alveoli
what is this organ?
trachea
what is 1?
- Type 1
Alveolar Septa is a thin layer of CT that surrounds and separates alveoli
Type I pneumocytes (I) are thin squamous cells that line the alveolar surface
Type II pneumocytes (II) are secretory cells that aggregate at septal junctions (so the bottom 2 arrows for #2 are incorrect)
What is this outlined structure?
Distal convoluted tubule – if the cells are arranged in order with no microvilli. Cuboidal to columnar cells.
Distal straight tubule – still missing a few cells, but fewer cells are missing and they are smaller. A few microvilli.
Organ: kidney
what are these circles?
Proximal Convoluted tubule (PCT) is the first segment of renal tubule and is made of simple cuboidal epithelia with microvilli.
Organ: kidney
Outlined structure?
Visceral layer of Bowman’s capsule
(if the white part was included, then it’d be Parietal Bowman’s capsule, I think)
General tissue type?
Specific tissue type?
General: Transitional epithelium
Specific: Lining of bladder
What is this layer?
Circular layer of smooth muscle / muscularis
(Transitional epithelium of Ureter)
general tissue type?
specific?
General: parakeratinized stratified squamous epithelium
Specific: mastitory mucosa
Creepy Mouth Thing?
Tonsillar crypt!
Tissue type?
Simple columnar epithelia with microvilli (OR w/ striated border)
Cell?
Organ?
The cell is enteroendocrine cell. Organ is small intestine
Aqua structure?
Orange circle in upper left?
Red circle?
Aqua structure? goblet cells
Orange circle in upper left? Mast cells
Red circle? Lymphocytes
Green Circle?
Blue structure?
Yellow circles?
Green: Paneth cells with granules that contain lysozyme and stain very pink
Blue: Enteroendocrine cells have basophilic (purple granules)
Yellow: plasma cells
Organ?
APPENDIX. Lots of lymph nodules in a ring. No villi.
What is this?
General tissue type
Specific tissue type
Bronchiole!
General: Pseudostratified columnar epithelia with cilia.
Specific: bronchiole epithelium
If it was a terminal bronchiole it would have smaller cilia and it would be simple columnar or simple cuboidal.
Tissue type?
Tissue type: pseudostratified columnar epithelia with cilia. Also has hyaline cartilage.
Outline?
Spongy urethra
what are these cells?
Purple cells: Secretory acinar cells
The red squamous cells on the outside like pink fibroblasts are
myoepithelial cells.
Organ: Mammary gland.
what are the stages?
Left: Proliferative phase.
Organ: uterus.
Layer: endometrium.
Right image is showing secretory phase (99% sure)
phase?
proliferative phase
what structure is this in the outline?
tertiary/graafian follicle
what are these cells?
spermatazoa
within testes
what are the Christmas trees (A)?
B - condensed chromatin cells?
C - rest on basal lamina?
D - uniform dots?
A - sertoli cells
B - spermatocytes
C - spermatagonia
D - spermatids
