Assertion :- When the muscle fibre contracts, sacromere length is reduced. Reason :- Sliding of myosin filament occurs due to rotational movement of myosin head.

The myosin myofilament can be cleaved into a head and a tail piece. All of the following are accurate in describing the position of myosin in a sacromere except (i) A-band is the length of a myosin myoilaments (ii) A-band contains thin and thick myofilaments (iii) A-band does not include actin-binding sites
