Sarcomere is the structural and functional unit of myofibril and area between
1 I to I band
2 \(\mathrm{Z}\) to \(\mathrm{Z}\) band
3 I band to \(Z\) line
4 A to I band
Explanation:
Sarcomere is the portion of myofibril between two successive Z-lines. It is the structural and functional unit of myofibril.

In a resting state, the edges of thin filaments on either side of the ____ filaments partially overlap the free ends of the____filaments leaving the central part of the ____filaments. Fill in the blank
1 Thick
2 Thin
3 Thick or thin both
4 None of them
Explanation:
In a resting state, the edges of thin filaments on either side of the thick filaments partially overlap the free ends of the thick filaments leaving the central part of the thick filaments. This central part of thick filament, not overlapped by thin filaments is called the 'H' zone.

Major protein in the thick filaments of skeletal muscle fibre is
1 Myosin
2 Actin
3 Tropomyosin
4 Troponin
Explanation:
Major protein in the thick filaments of skeletal muscle fibre is Myosin. Each myosin filament is a polymerised protein, made up of monomeric protein units called meromyosin. Each meromyosin has 2 parts, a globular head with short arm and a tail. Head is called heavy meromyosin and tail is called light meromyosin.

Statement A : Smooth muscles are known as unstriated muscles Statement B : They are found close to skeletal components of body like bones
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Smooth muscles are located in the inner walls of hollow visceral organs of the body like the alimentary canal, reproductive tract, etc.

The activities of the visceral muscles are not under the voluntary control of the nervous system and are therefore known as
1 Non-striated muscles
2 Smooth muscles
3 Involuntary muscles
4 All of the above
Explanation:
The activities of the visceral muscles are not under the voluntary control of the nervous system and are therefore known as involuntary muscles.
