The tissue shown in image A is which organ? (pg w52)

small intestine

The tissue shown in image A (pg w52) is:

well-preserved

autolyzed

mechanically damaged

overfixed

autolyzed

The problem shown in image A (pg w52) could have been prevented by:

placing the tissue in fixative sooner

handling the tissue more carefully during gross examination

decreasing the fixation time

buffering the fixative

placing the tissue in fixative sooner

The tissue component that should be present but is missing in the tissue shown in image A (pg w52) is the:

lamina propria

muscularis mucosa

epithelium

adventitia

epithelium

The pigment seen in image B (pg w52) is most likely:

iron

formalin

mercury

bile

formalin pigment

The pigment seen in image B (pg w52) could most likely be removed by treating with:

alcoholic iodine

alcoholic picric acid

dilute hydrochloric acid

running water

alcoholic picric acid

The pigment shown in image B (pg w52) most likely:

is an exogenous hematogenous pigment

is an endogenous nonhematogenous pigment

occurred during fixation with mercury

occurred during fixation with acidic formalin

occurred during fixation with acidic formalin

The pigment shown in image B (pg w52) could have been prevented by:

washing well after fixation

keeping the pH of the fixative >6.0

treating the tissue with iodine and sodium thiosulfate

substituting paraformaldehyde for the formaldehyde

keeping the pH of the fixative >6.0

The tissue in image C (pg w53) has been screened for artifactual pigment by the use of:

fluorescent microscopy

dark field microscopy

polarizing microscopy

electron microscopy

polarizing microscopy

The technique used in image C (pg w53) uses a/an:

polarizer & analyzer

halogen lamp

electron gun

oblique light

polarizer & analyzer
