Myosin, [...]
The properties present in other muscle are also shown by the cardiac muscle. But it shows certain special features. 1. Rhythmicity: One of the main characteristic features of the cardiac muscle is that it can initiate its own impulse rhythmically. This inherent rhythmical property is present throughout the cardiac muscle as evident from the electro-physiological studies of the single fibre [...]
The following article will guide you about how muscles move bones at a joint in human body. Muscles work in the following way: (i) They can pull but never push. (ii) They pull only when they contract. (iii) When they contract, they decrease in length. (iv) When returning to their original length, they relax (not 'expand'). (v) They are attached [...]
