Funeral Service Sciences
About 26 of every 150 questions on a NBE Sciences practice exam come from this topic.
What to know
Review the supporting sciences: microbiology (bacteria, viruses, fungi, sterilization and disinfection), pathology (disease processes, postmortem changes, rigor, livor and algor mortis, decomposition), anatomy (vascular system, body cavities, regions and landmarks) and chemistry (organic compounds, aldehydes, pH and buffers) as they apply to the deceased.

Try a practice question
Mycobacterium tuberculosis is described as acid-fast. This property is mainly due to which cell wall feature?
- AA protective polysaccharide capsule
- BAn outer membrane rich in endotoxin
- CAn unusually thin peptidoglycan layer
- DHigh content of waxy mycolic acids
Show the answer
High content of waxy mycolic acids. Mycolic acids make the mycobacterial wall waxy, so it holds stain even after an acid-alcohol wash. The same waxy wall contributes to its resistance to some disinfectants.
