Cillia
____ in a frog’s inner ear allow it to detect sounds from its environment. Through these, frogs have a mechanism to detect and escape from potential threats.
Stereocillia
are tail-like structures that provide motility to cells.
Flagella
are both found at the basement membrane of epithelial cells.
Basal infoldings and hemidesmosomes
help the epithelial tissue provide protection and structural support to the underlying cells.
Hemidesmosomes
are responsible for increasing surface area and for ion and fluid transport.
Basal infoldings
are found in epithelial cells and are mainly responsible for connecting adjacent cells. Combination
Cell junctions
prevent leakage of substances.
Tight junctions
connect adjacent cells. More bigger
Adherens Junctions
connect adjacent cells. Lower part
Desmosomes
serve as channels of ions, water and other essential substances.
Gap junctions
Are biconcave to aid in the diffusion of gases from the air sacs of the lungs and into the oxygen-deprived tissues of the rest of the body. Transport of Oxygen
Red blood cells
