Dictionary » T » T tubule T tubuleDefinition noun A deep invagination of the sarcolemma which appears as a small tubule that runs transversely from the sarcolemma across the myofibril of striated muscle.
The entire region of the striated muscle cell must contract simultaneously. Since a striated muscle fiber is relatively large, the narrow, small tubules (T-tubules) allow rapid depolarization of the membrane. The tubules are studded with a large number of L-type calcium channels that serve as passageway for the rapid transmission of electrical impulses to the interior of the cell. These impulses, or action potentials, are the trigger for muscle fiber contraction.

Results from our forumglucose absorption... in the extracellular space than in the cell. The classic examples of cells using Na/glucose symporters are enterocytes and cells of the proximal tubule of the tubule, but there may be other cells where this particular transporter is expressed. As for your second question: I don't exactly what ...

Renal... whereas osmotic pressure by the tissue. So, if hydrostatic pressure is higher than osmotic pressure, does it mean that more water enter the renal tubule? 3) I don't understand how osmotic pressure is dependent on the protein concentration. Thanks in advance! Maruko

Seminiferous tubulesImagine a pipe, it is one seminiferous tubule. If you cut it transversally, you will get circular shape like ring shape. if you cut it longitudinally, you will get another shape, if you cut it diagonally, you will get another shape, etc. etc.

Seminiferous tubulesThat makes not a lot of sense. Do you mean cross section diagram from a book or a real image of a seminiferous tubule?
