    Tissue remains in one container but reagents get changed at schedule interval

    TISSUE TRANSFER PROCESSOR

  • 3

    Automated tissue transfer processor where the cassettes are in the processing chamber while the different reagent are pumped into the chamber

    FLUID TRANSFER PROCESSOR

  • 4

    Fixation primary aim is to preserve cell

    MORPHOLOGY, CHEMICAL INTEGRITY

  • 5

    Fixation secondary aim is to make tissues

    HARDEN

  • 6

    Formaldehyde fixes tissue by forming

    METHYLENE BRIDGE

  • 7

    Type of fixative which is taken in and become part of the tissue

    ADDITIVE

  • 8

    Type of fixative which is not taken in and it facilitates the removal of water forcross-links to form

    NON-ADDITIVE

  • 9

    Practical consideration which the specimen should be placed in fixative as soon as it is removed from the body

    SPEED

  • 10

    Volume of fixative must be placed in a tissue that is not yet fixed

    20x THE VOLUME OF TISSUE

  • 11

    Formalin diffuses into the tissue approximately

    1 MM/HOUR

  • 12

    Important in maintaining the microenvironment of cells as it ensures that cells are morphologically clear (especially under microscope) ensuring that cells are intact

    OSMOLALITY

  • 13

    The best general fixative

    10% NEUTRAL BUFFERED FORMALIN

  • 14

    Microscopy use in slightly hypertonic (400-450 mOsm)

    LIGHT MICROSCOPY

  • 15

    Microscopy use in more or less isotonic (340 mOsm)

    ELECTRON MICROSCOPY

  • 16

    Hasten the penetration of formalin into the tissue

    TEMPERATURE

  • 17

    Increases the penetration of formaldehyde

    AGITATION

  • 18

    Type of fixative made up of only one component /substance

    SIMPLE

  • 19

    Type of fixative made of 2 or more fixatives

    COMPOUND

  • 20

    Type of fixative that permits the general microscopic study of tissue structures. It Focuses on the anatomy of cells

    MICROANATOMIC

  • 21

    Type of fixative that preserve the specific parts and particular microscopic structure. It preserves Nuclear and Cytoplasmic fixatives

    CYTOLOGICAL

  • 22

    Type of fixative that preserve chemical contents (CHO, glycogen, mucopolysaccharide)

    HISTOCHEMICAL

  • 23

    To improve the demonstration of particular substances. For special staining techniques possible (with secondary fixative acting as a mordant) to ensure complete hardening and preservation

    SECONDARY FIXATION

  • 24

    For grams staining; mordant is

    IODINE

  • 25

    Improves the staining, optical differentiation of diff parts of tissue

    MORDANT

  • 26

    A form of secondary fixation whereby a primarily fixed tissue is placed in aqueous solution of 2.5-3% potassium dichromate for 24hours to act as mordant. It is for better staining effects and to aid in cytologic preservation of tissues

    POST CHROMATIZATION

  • 27

    Process of removing excess fixative from the tissue after fixation in order to improve staining and remove artifacts from the tissues

    WASHING OUT

  • 28

    Removal of black granular deposit using alcoholic iodine

    OSMOLALITY

  • 13

    The best general fixative

    10% NEUTRAL BUFFERED FORMALIN

  • 14

    Microscopy use in slightly hypertonic (400-450 mOsm)

    LIGHT MICROSCOPY

  • 15

    Microscopy use in more or less isotonic (340 mOsm)

    ELECTRON MICROSCOPY

  • 16

    Hasten the penetration of formalin into the tissue

    TEMPERATURE

  • 17

    Increases the penetration of formaldehyde

    AGITATION

  • 18

    Type of fixative made up of only one component /substance

    SIMPLE

  • 19

    Type of fixative made of 2 or more fixatives

    COMPOUND

  • 20

    Type of fixative that permits the general microscopic study of tissue structures. It Focuses on the anatomy of cells

    MICROANATOMIC

  • 21

    Type of fixative that preserve the specific parts and particular microscopic structure. It preserves Nuclear and Cytoplasmic fixatives

    CYTOLOGICAL

  • 22

    Type of fixative that preserve chemical contents (CHO, glycogen, mucopolysaccharide)

    HISTOCHEMICAL

  • 23

    To improve the demonstration of particular substances. For special staining techniques possible (with secondary fixative acting as a mordant) to ensure complete hardening and preservation

    SECONDARY FIXATION

  • 24

    For grams staining; mordant is

    IODINE

  • 25

    Improves the staining, optical differentiation of diff parts of tissue

    MORDANT

  • 26

    A form of secondary fixation whereby a primarily fixed tissue is placed in aqueous solution of 2.5-3% potassium dichromate for 24hours to act as mordant. It is for better staining effects and to aid in cytologic preservation of tissues

    POST CHROMATIZATION

  • 27

    Process of removing excess fixative from the tissue after fixation in order to improve staining and remove artifacts from the tissues

    WASHING OUT

  • 28

    Removal of black granular deposit using alcoholic iodine

    DEZENKERIZATION
