APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Papillary muscles are present in the ventricles of the heart. Chordae tendineae, the thread-like tendons of papillary muscles prevent the valves of the heart from movement by holding the flaps tightly against the strong flow of blood that is inserted upon the flaps of the tricuspid and bicuspid valve.

Detailed explanation-2: -Chordae tendineae: The chordae tendineae, also known as the heartstrings, are cord like tendons that connect the papillary muscles to the tricuspid and bicuspid valves of the heart.

Detailed explanation-3: -Subvalvular apparatus: The papillary muscles and the chordae tendineae, known as the subvalvular apparatus, hold the valves closed so that they do not prolapse.

Detailed explanation-4: -The valves prevent the backward flow of blood. Valves are actually flaps (leaflets) that act as one-way inlets for blood coming into a ventricle and one-way outlets for blood leaving a ventricle. Normal valves have 3 flaps (leaflets), except the mitral valve.
