Two important types of muscle are skeletal and smooth muscle. Their similarities and differences are described with regard to general morphology and ultrastructure (arrangement of filaments and T tubules), linking structure to physiological functions. The sliding-filament theory of muscle contraction is explained. Finally, the processes by which nerves excite muscle contraction (excitation–contraction coupling) are outlined, again relating variations in these processes in the two types of muscle to differences between them in their role in the body. |
