Identify the incorrectly matched pair:
Type of epithelium | Location | |
1. | Simple squamous | Blood vessels and alveoli |
2. | Simple cuboidal non brush bordered epithelium | Proximal convoluted tubule |
3. | Columnar epithelium | Stomach and small intestine |
4. | Ciliated epithelium | Bronchioles and fallopian tubes |
Unicellular glands located in the alimentary canal are called as:
1. | Paneth cells | 2. | Peyer’s patches |
3. | Goblet cells | 4. | Histiocytes |
What type of epithelial cell junctions facilitate the cells to communicate with each other?
1. Gap junctions
2. Adhering junctions
3. Tight junctions
4. Plasmodesmata
The cell junctions in animal tissues that perform the function of cementing to keep neighbouring cells together are known as:
1. Tight junctions
2. Adhering junctions
3. Gap junctions
4. Desmosomes
Column I | Column II | ||
A. | Tight junctions | i. | Allow passage of ions and small molecules between cells |
B. | Desmosomes | ii. | Prevent the passage of molecules between cells |
C. | Gap junctions | iii. | Provide mechanical strength |
Presence of intercalated discs help cardiac muscles to act as a functional syncytium. This is possible because the structure of these discs have:
1. | Tight junctions | 2. | Gap junctions |
3. | Adhering junctions | 4. | Plasmodesmata |
