Labelling and fixation (histopathology)

In histology procedure, once the tissue has been selected for processing, what is the next step?

• trimming

• labeling

• embedding of tissue

• sectioning

Is it true, after biopsy or specimen collection, they must be labelled and bear the same number in all stages of procedure.

• yes

• no

By using which of the following materials can the labeling be done in the histological procedure?

• graphite pencil-led typewritten

• yes

• no

In histological procedures, labeling with SK (stock kept) at the end of grossing notes are written for which type of specimen?

• no tissue is left or no remainings left from the specimen

• remainings of all specimens and are preserved in formalin

What is the primary function of fixatives?

• preserve cell structure

• damages the specimen

• increases autolysis

• sectioning of specimen

The process in which, there is degradation of cellular structure due to degenerative enzymes from excised tissue itself is called?

• necrosis

• autolysis

• autopsy

• all of the above

What is the other use of fixative in histology?

• allowing easy handling of specimen during processing

• to protect and harden the tissue

• increases autolysis

• both A and B

What amount (volume) of fixative should be used for the specimen (tissue)?

• 5 times more fixatives than the tissue volume

• 20 times more fixatives than the tissue volume

• 10 times more fixatives than the tissue volume

Which types of samples take longer hours to reach deeper tissue?

• larger samples

• smaller samples

• it does not depend on the size
