MODULE 1 : CYTOLOGY Flashcards
A part of slide preparation in which to obtain a rigid consistency of the specimen for sectioning
EMBEDDING
A part of Slide preparation to preserve tissue morphology and architecture and prevent cell digestion
FIXATION
A part of slide preparation which uses lipid solvent like Benzene or Xylene to remove Alcohol
CLEARING
Part of Slide preparation where the tissue is cut for light microscopy or electron microscopy using a microtone
SECTIONING
A common type of basic dye used for staining
HEMATOXYLIN
BLUE : nucleus; acidic regions of cytoplasm; cartilage matrix
A common type of acidic dye used for staining
EOSIN
PINK : basic regions of cytoplasm; collagen fibers
Contains the DNA that encodes the instructions for synthesis of all proteins and enzymes of the cell
NUCLEUS
Contains the organelles and inclusions suspended in a fluid medium called CYTOSOL / Principal site of metabolic functions of the cell
CYTOPLASM
- metabolically active
- internal cellular organs w/ specific funtions
- essential
- membrane bound
ORGANELLES (compare with INCLUSIONS)
- metabolically inert
- accumulation of cell products
- dispensable
- not bounded by a membrane
INCLUSIONS (compare with ORGANELLES)
Composed of phospholipids and proteins
CELL MEMBRANE
Found in the OUTER and INNER SURFACE of cell
HYDROPHILIC head portion of lipid (plasma membrane)
found in the MIDDLE portion of plasma membrane
HYDROPHOBIC tail portion of lipid
A type of membrane protein which spans the entire width of plasma membrane
INTRINSIC PROTEIN
A type of membrane protein which is found in inner or outer surface
EXTRINSIC PROTEIN
