Actin filaments are thinner as compared to the myosin filaments. 4. In the centre of each ‘I’ band is an elastic fibre called ‘Z’ line which bisects it. 5. The portion of the myofibril between two successive ‘Z’ lines is considered as the funct
Options
- ABoth 1 and 2 are correct
- BBoth 1 and 2 are incorrect
- COnly 5 is correct
- DBoth 2 and 4 are correct
Correct answer
B. Both 1 and 2 are incorrect
Step-by-step solution
Visceral muscles do not exhibit any striation and are smooth in appearance. Hence, they are called smooth muscles (nonstriated muscle).,Actin filaments are thinner as compared to the myosin filaments,The portion of the myofibril between two successive ‘Z’ lines is considered as the functional unit of contraction and is called a sarcomere
