Answer:

The correct answer will be option-B.

Explanation:

Papillary muscles are the muscle present in the ventricle of the heart to which chordae tendinae of the aortic valves gets attached.

The number of papillary muscles varies in both the ventricles as in the right ventricle, three papillary muscles are present whereas in the left ventricle two muscles.

They play an important role in the closing of the AV valves as ventricular contraction causes the chordae tendinae to contract which in turn contract the papillary muscles thereby closing the AV valve and prevent back-flow of the blood to the atria.

Thus, Option-B is the correct answer.

papillary muscles by chordae tendineae. During the relaxation phase of the cardiac cycle, the papillary muscles are also relaxed and the tension on the chordae tendineae is slight (see Figure 12b). However, as the myocardium of the ventricle contracts, so do the papillary muscles. This creates tension on the chordae tendineae (see Figure 13b), helping to hold the cusps of the atrioventricular valves in place and preventing them from being blown back into the atria.

NISA [10]

An unconscious adult victim is gasping for breath and having difficulty breathing. The scene is safe and help has been called. Next you should use the head tilt chin lift procedure.

An unconscious patient is at risk of blocking their airway and suffocating. The main reason for this occurring is due to the tongue. An unconscious patient loses all their muscular tone, and this includes the tongue! The tongue can fall back and block the airway.

This situation is an emergency – without a supply of oxygen reaching the lungs, the patient will suffocate in a matter of minutes.

In CPR, we use the head-tilt, chin-lift method to open the airway.

How to Perform a Head-tilt Chin-lift :

  1. Kneel next to the patient’s head
  2. Place one hand on the patient’s forehead and tilt the head gently backward
  3. Place two fingers under the bony part of their chin and lift the chin vertically upwards
  4. Take care not to place any pressure on the soft part of the neck as this could obstruct the airway

If a cervical spine injury is suspected, then the modified jaw thrust would be used in place of "head-tilt, chin-lift". The jaw thrust is a technique used on patients with a suspected spinal injury and is used on a supine patient.
