Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An attachement plaque between a cell and a noncellular surface is called a:
A
Desmosome
B
Tight junction
C
Hemidesmosome
D
Gap junction
Explanation: 

Detailed explanation-1: -Hemidesmosome is the attachment plaque or cellular junction between a cell and noncellular surface. This is the form of attachment in the area between the noncellular basement membrane and the basal layer cells of the stratified squamous epithelium.

Detailed explanation-2: -Hemidesmosomes are multiprotein complexes that facilitate the stable adhesion of basal epithelial cells to the underlying basement membrane. The mechanical stability of hemidesmosomes relies on multiple interactions of a few protein components that form a membrane-embedded tightly-ordered complex.

Detailed explanation-3: -Hemidesmosomes (HD) are specialized junctional complexes, that contribute to the attachment of epithelial cells to the underlying basement membrane in stratified and other complex epithelia, such as the skin, the cornea, parts of the gastrointestinal and respiratory tract, and the amnion.

Detailed explanation-4: -Hemidesmosomes are multiprotein complexes that facilitate the stable adhesion of basal epithelial cells to the underlying basement membrane. The mechanical stability of hemidesmosomes relies on multiple interactions of a few protein components that form a membrane-embedded tightly-ordered complex.
