Muscle contraction RyRs are activated by a calcium trigger, which is brought about by the flow of through the L-type calcium channels. Furthermore, cardiac muscle tend to exhibit diad (or dyad) structures, rather than triads. Excitation-contraction coupling in cardiac muscle cells occurs when an action potential is initiated by pacemaker cells in the sinoatrial node or Atrioventricular node and conducted to all cells in the heart via gap junctions. The action potential travels along the surface membrane into T-tubules (the latter are not seen in all cardiac cell types) and the depolarisation causes extracellular to enter the cell via L-type calcium channels
Maite (given name) to: Maite (given name) Maite ( ) is a female given name of Basque origin meaning "love". It has become a popular name throughout Spanish-language countries, where it is usually stressed on the first syllable. Alternatively, it is also the Spanish nickname (sort of a contraction) for both "María Teresa" and "María Esther", in which case it is most frequently stressed on the last syllable and spelled with y, thus Mayté.
