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

Statements 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.

Which of the following statements is/are correct/ incorrect? (I) A-bands of the muscle is dark and contain myosin. (II) I-bands are the light bands and contain actin. (II) during muscle contraction, the A-band contracts. (IV) The part between the two H-lines is called as sarcomere. (V) The central part of thin filament, not overlapped by thick filament is called H-zone.

Statements : 1. A bands are dark and contain myosin 2. I-bands are light and contain actin 3. During action, A band contracts 4. Part between two Z-lines is sarcomere 5. Central part of thin filament, not overlapped by thick filaments is H-zone.

In a resting muscle,the central part of thick filament in a sorcomere is not overlapped by thin filament.This central part is called

Read the given Statements for skeletal muscles (i) Thin filaments are firmly attached to the Z - line . (ii) The light band is also called the I - band and contains mostly actin. (iii) A sarcomere is the functional unit of a myofibril between two adjacent A - bands . (iv) The central part of the thick filament , not overlapped by the thick filament is called the H - zone Which of these is/are CORRECT ?

Assertion : Contraction of a muscle fibre takes place by the sliding of the thin filaments over the thick filaments. Reason : The central part of thick filament is not overlapped by thin filaments in a resting state.
