Question

Papillary muscles are found in mammalian
A) Auricles
B) Ventricles
C) Pinna
D) Eyes

Answer 1

Hint:Chordae tendineae are defined as the fibrous structure which has a comb-like appearance. They are connected to the tricuspid and mitral valve. These valves help to stop the blood from flowing back into the atria when ventricles undergo contraction.

Complete answer:
Chordae tendineae are defined as the cord-like structures present within the heart. They are connected to the atrioventricular valve-AV valves (also termed as the Bicuspid valve on the left side of the heart and atrioventricular valve on the right side).
-On one side they're attached to the valve of the heart while on the opposite side they’re attached to the papillary muscles that are present in the ventricles.

Now let us find solution from given options:
A) Auricles: they are the chambers of heart. These contain bundles of his. They collect blood from lungs and body and transfer into the ventricles.
B) Ventricles: chordae tendineae are present in the heart and at one end they are connected to the valve of the heart and that of the opposite side they are connected to that of the papillary muscles that are present in ventricles.
C) Pinna : it is the part of the outer ear. It collects vibrations from the external environment and transmits the sound to external auditory meatus.
D) Eyes : they are the sensory organs that help to vision and see things. They contain ciliary muscles which helps in contraction and relaxation of the eyes.

Hence the correct answer is ‘B’ that is ventricles.

Note:The chordae tendineae plays a very important function of anchoring the AV valves to ventricular papillary muscles are to anchor and protect the AV valves to the papillary muscles of the ventricles and to keep the valves in a closed position whenever there is ventricular systole so that blood doesn't flow back in the atria.
