Which structure, do you think, would prevent the pushing of muscular flaps cuspid valves into atrium during ventricular contraction?
1 Mitral valve
2 Thebasian valve
3 Moderator band
4 Chordae tendineae
Explanation:
Chordae tendineae, are special fibrous cords that are attached to the flaps of bicuspid and tricuspid valves of the heart, it is joined to the other end with special muscles of the ventricle called as papillary muscles.

Which of the following show striations, involuntary in nature, not under the control of CNS?
1 Skeletal muscles
2 Cardiac muscles
3 Voluntary muscles
4 Smooth muscles
Explanation:
Cardiac muscles show striations, involuntary in nature, not under the control of CNS.

Visceral muscles are also called
1 Smooth muscles
2 Involuntary muscles
3 Striated muscles
4 Both 1 and 2
Explanation:
Visceral muscles do not exhibit any striation and are smooth in appearance. Hence, they are called smooth muscles (nonstriated muscle). The activities of smooth muscles are not under the voluntary control of the nervous system and are therefore known as involuntary muscles.
