Question

Welded areas between adjacent cells are :

• A. Desosomes
• B. Gap junctions
• C. Intercellular bridges
• D. Inter digitations

Answer 1

The correct option is A Desosomes

Welded areas between adjacent cells are desmosomes. Adjacent membranes possess disc-shaped thickenings of about 0.5 $\mu$m diameter, a number of tonofibrils and trans-membrane linkers are embedded in dense intercellular material. Desmosomes function as spot welds and are hence called spot desmosomes. They occur in epithelia subjected to disruption.
