- 1what type of tissue prep method was used?spread prep
- 2what type of slide prep was used ?spread prep
- 3what type of preparation was used for this specimen?Teased prep
- 4what is this and what type of prep was used?bone, ground prep
- 5What type microscopy and what type of stain was usedLight Microscopy
H&E
- 6What type of microscopy was used ?scanning electron
- 7What type of microscopy was used ?transmission electron
- 8Name this cytoskeletal elementmicrofilaments, made of action
- 9name this cytoskeletal elementmicrotubule, made of tubulin
- 10Name this cytoskeletal elementCilium, arranged in a 9+2
- 11Name this cytoskeletal elementcentriole, arranged in 9*3 arrangement
- 12What is this formation and what is it made of?Mitotic spindle, made of microtubules
- 13What is this cytoskeletal element?intermediate filament
- 14What is the junction type located at the arrows?Tight junction
- 15What is the junction type located at "AdB"?Adheren Junction
- 16What is a metabolic by-product found on the cytoplasm?inclusions
(Shown: lipid droplets)
- 17What is located below the adheren junction and how can it be seen?Desmosomes, connecting both cells. you can see hairy look around each side of the meeting cells
- 18What type of junction can be see in this and how?This shows a hemidesmosome. you can see that the dark hairy area is only located on one side.
- 19Where will you find a gap junction?they are usually between the adheren junction and the desmosomes. You can see that they have a beaded look. This picture shows the pores of connexons
- 20What is the pale substance within this nucleus? Dark?Pale: euchromatin
Dark: heterochromatin (you can distinguish this from the nucleoli because the nucleoli is more dense)
- 21What is the purpose of the darkest circle that the arrow is pointing to?Nucleoli, within the nucleus
it is the site where rRNA is transcribed and assembled with ribosomal proteins to make functional ribosomes
- 22Name the dense, dark, substancenucleoli
- 23Label 2 3 42. Lumen of RER, black dots are proteins that are spit out by the RER, usually for ejection
3. Heterochromatin
4. Nuclear pore
- 244 things seen in this: RER Lumen of RER Smooth ER Free RibosomesLabels can be seen on lecture
- 25This is an electron micrograph (EM) of?What is C labeling?This is an EM of the RER
C. cytoplasm between the RER
- 26—See Nissl Bodies- stacks of RER
Nucleus, Heterochromatin, nucleolus
- 27—TEM of Golgi, see, cis, medial, and trans
- 28—This is showing a lysosome with ingested material
- 29What are the dark circles and what is their functionPeroxisomes
produce H2O2 and are involve din alcohol detox and breakdown of long chain fatty acids
- 30—Mitochondria
- 31What is this showing and why is there so many?This is muscle tissue, mitochondria (darker) are found in between the contractile units because muscle contraction requires so much ATP
- 32Mitochondria are located at the _____ side of this cell.Basil - this is because there are probably enzymes located there that need the energy. Mitochondria are located in the area where they are used
(you can also see nuclear envelope, cytoplasm, heterochromatin)
- 33Name this stage of mitosis in IFInterphase
- 34Name this stage of mitosis in IFProphase
centrosomes separate, chromosomes condense
- 35Name this stage of mitosis in IFPrometaphase
Nuclear envelope (NE) breaks down
chromosomes attach to spindle
- 36Name this stage of mitosis in IFMetaphase
chromosomes align on spindle equator
- 37Name this stage of mitosis in IFAnaphase A
sister chromatids separate and move to poles
- 38Name this stage of mitosis in IFAnaphase B
Cleavage furrow (CF) assembles
Organized central spindle assembles
Poles separate
- 39Name this stage of mitosis in IFTelophase
Cleavage furrow constricts
Nuclear envelope reassembles
- 40Name this stage of mitosis in IFCytokinesis
Chromosomes decondense
Interphase microtubule network reforms
Daughter cells separate
