the role of the terminal bar of the cell membrane

Postby how_2_pharma » Wed Aug 17, 2005 12:44 am

hi,
i have been studying the role of the cell membrane in the active and passive transport, and i found that there are specific sites in the cell membrane where the transport occures, a desmosome, how is that related to the terminal bar, and what exactly is it? :?
thanks

A desmosome in general keeps cells tightly bound to each other because they are connected to inetrmediate filaments of the cytoskeleton.More info about desmosomes is probably found on the internet.

great, but is it a related to the terminal bar? and does the terminal bar has any thing to do with the cell transport of substances?
thanks for your time.

the answers to those questions can be found in an histology book. As far as i know desmosomes haven't got anything to do with cellular transport. Tight junctions are responsible for that to maintain polarization of the cells.
