A-bands of the muscle are dark and contain myosin
I-band are the light bands and contain actin
During muscle contraction the A-band contracts
The part between the two Z-lines is called as sarcomere
The central part of thin filament, not over-lapped by thick filament is called H-zone of the above statements.

Text Solution

Verified by Experts

The correct Answer is:
D
* A band : It is the darker middle part of the sarcomere which extends the entire length of the thick filament.
* I band : It is lighter, less dense area that contains the rest of the thin filament.
* H zone : Towards each end of the A band is a zone of overlap where the thick and thin filament lie side by side.
* M line: It is the fibrous membrane holds the A band together and passes through the middle of each A-band
