Question

Dead skin cells are shed in thin sheets because they are held together by "spots" of proteoglycan reinforced by intermediate filaments. Such strong intercellular connections are called
A) tight junctions.
B) intermediate junctions.
C) desmosomes.
D) junctional complexes.
E) gap junctions.

Answer 1

Answer:

Desmosomes.

Explanation:

The cell communication can occur through the signaling molecules and the junctions present in the body. These junctions allows the molecules to pass through the different sites of the body.

Desmosomes are the cell adhesion molecules that transmit the information between two cells only and not between the cell and extracellular matrix. This junction is also known as macula adherens. The dead and injured cells are drained in the desmosomes.

Thus, the correct answer is option (C).

Answer 2

Answer:

Option C, desmosomes

Explanation:

Desmosomes are adhesive proteins that are found in the intercellular junction and maintain the mechanical strength of tissue by forming stable adhesive junctions between the cells . They are also known as adhering spots. Desmosomes can interact with the intermediate filaments of muscle cells and proteins to maintain tissue rigidity and structure. Apart from holding cells together, they are also responsible for regulating the biochemical signaling pathways.

Hence, option C is correct
