Within the multicellular organism tissues, a cell junction occurs. Animals have four kinds of intercellular junctions which are gap junction, desmosomes, adherens junction and tight junction,
Tight Junctions, Desmosomes, and Gap Junctions in Animal Cells
plasmodesmata tight junctions desmosomes gap junctions the plasmodesmata is the only cell junction in the plant cells.. and the other three cell junctions are in the animal cells...
If the answer choices are a. Extracellular Martix b. Desmosomes c. Gap Junctions d. Tight Junctions e. Peroxisomes Then the answer is definitely C, Gap Junctions
Animal cells are mostly bound together by what are known as intercellular junctions. There are three types of cell junctions: anchoring junctions, tight junctions and gap junctions. Of these, anchoring junctions, which include adherens junction, desmosomes and hemidesmosomes, help bind the animal cells together, in an extracellular matrix.
The apical surface does not have any cell junctions because it is a free surface exposed to things that are not epithelial cells. The lateral surfaces of an epithelial cell, which face the adjacent cells on either side contain tight junctions, adherens junctions, desmosomes and/or gap junctions. The basal surface of an epithelial cell adhere to extracellular materials like the basement membrane. Hemidesmosomes anchor the epithelium to the basement membrane in the basal surface.
In vertebrates, there are three major types of cell junction:1. Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions.)2. Gap junctions (communicating junction)3. Tight junctions (occluding junctions)Your question most likely is for the tight junction but more information in the question would be helpful.
The body is made up of three major extracellular materials. These materials are; body fluids, cell secretions and extracellular matrix.
hypovolemic shock and edema
cells, fibers, and extracellular matrix. (:
