Histology
Cards in this deck (21)
- 1—Lipid Droplets
- perfectly even/round/lighter shaded because they are less electron dense.
- located in adiposite (fat cells)
- always same size
- usually aggregate - 2—Rough Endoplasmic Reticulum
- ribosomes only
- highly organized cisterna
- continuous with SER
- 3—Smooth Endoplasmic Reticulum
- productions of sterols
- continuous with RER
- unorganized random and different orientation / some oblong
- 4—Ribosomes
- only of rough ER
- part of protein synthesis
- 5—Cell Membrane
- dark line, surrounds cilia (fingers in gloves)
- 6—Secretory Vesicles
- dark shaded (normally)
- circular but not all the same shape and size as opposed to lipid droplets
- 7—Rough Endoplasmic Reticulum
- ribosomes only
- highly organized cisterna
- continuous with SER
- 8—Mitochondria
- OMM / IMM / CRISTAE (folds of IMM to increase SA)
- matrix (Krebs) is space inside, intermembrane space is between OMM and IMM
-
- 9—Golgi Complex
- highly organized stacks of cisterna
- NO RIBOSOMES
- SECRETORY VESICLES RELEASED FROM
- 10—Secretory Vesicles
- dark shaded (normally)
- circular but not all the same shape and size as opposed to lipid droplets
- 11—Secretory Vesicles
- dark shaded (normally)
- circular but not all the same shape and size as opposed to lipid droplets
- 12—Rough Endoplasmic Reticulum
- ribosomes only
- highly organized cisterna
- continuous with SER
- 13—Microtubules
- Cilia made from, hollow (2 lines)
- MF not hollow
- 14—Microfilaments
- hard to tell from intermediate filaments
- not hollow but filled/filamentous
- inside microvilli
- 15—Intermediate Filaments
- hard to tell from microfilaments
- 16—Glycogen Granules
- storage of glycogen
- 17—Nucleolus
- large (1 or 2)
- dark and electron dense
- CIRCULAR
- 18—Heterochromatin
- very dense ( electron dense) = dark
- small scattered and not circular
- DNA wrapped around histones
- 19—Euchromatin
- light / loosely packed ( not electron dense)
- don't need to be dense because needs to have room for the machinery of transcription to occur.
- spread out
- 20—Nuclear Pore Complexes
- many many proteins that assist in bringing things in and out of nucleus
- 21—Nuclear Pore Complexes
- many many proteins that assist in bringing things in and out of nucleus
