KROK 1 2014 – Question 121 · KROK (Medicine) · Histology, Cytology, and Embryology
An electron micrograph shows a cell-to-cell adhesion consisting, in each cell, of an attachment plaque. The intercellular space is filled with electron-dense substance including transmembrane fibrillar structures. Specify this adhesion:
- A. Synapse
- B. Tight junction
- C. Desmosome
- D. Nexus
- E. Adherens junction
Hint
Compare what lies on the cytoplasmic face of the membrane and what spans the gap between the cells in each type of junction.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
