Question

How many papillary muscles are typically found in the right ventricle and why?

a) Two, for structural reinforcement
b) Three, for valve stabilization
c) Four, for chordae tendineae attachment
d) Five, for muscle contraction support

Answer 1

In the right ventricle, there are three papillary muscles connected to the tricuspid valve via chordae tendineae. The purpose of the papillary muscles and chordae tendineae is to prevent backflow of blood during ventricular contraction, ensuring that blood flows in one direction.

Step-by-step explanation:

Papillary Muscles in the Right Ventricle

In the right ventricle, there are three papillary muscles called the anterior, posterior, and septal muscles. These papillary muscles are connected to the tricuspid valve via chordae tendineae. The purpose of the papillary muscles and chordae tendineae is to prevent backflow of blood during ventricular contraction, ensuring that blood flows in one direction.
