The third instalment of our biomedical science quiz. This time, we have a picture round and eight questions relating to ultrastructure, compiled by Catherine Griffiths, an Electron Microscopist from the Biomedical Imaging Unit at University Hospital Southampton.
Round 1: Picture round
- What is the tubular structure in the centre of the image? (Nucleus to the right)
- Which insulating layer shown here allows efficient transmission of electrical impulses?
- These cilia and microvilli in cross section can be found on which type of cell?
- What is the name for this cluster of capillaries?
- A symptom of multiple myeloma, this image shows crystalline paraprotein deposit in which tissue type?
- What is the banded fibrous structure shown here?
- What sort of cells are these homogeneous electron-dense structures?
- Which technique allows us to see viruses by TEM, such as this rotavirus cluster, by staining the background?
