What else can I help you with?
What muscle is attached to the chordae tendineae?
papillary muscles
Small muscle masses that function to regulate the atrioventricular valves?
These small muscles are called papillary muscles. There are five total papillary muscles in the heart, three in the right ventricle and two in the left.
What is the function of the cordinae and the muscle that attach to them?
The chordae tendinae and their attachments to the papillary muscles prevent the AV valves from collapsing backwards into the atria.
Does the papillary muscle surround the pericardial sac?
No
Structure from which chordae tendineae originate?
Chordae tendinae is attached to papillary muscle and the valves.
What is the muscle that attached to chordae tendinae?
papillary muscles
Where are the papillary muscle?
inside the left and right ventricle
Is the papillary muscle only present on the left side of the heart?
no.
Name the structure between the left atrioventricular valve and the papillary muscle?
The chordae tendineae connect the AV valve and the papillary muscle. These structures work together to prevent backflow from the ventricle to the atrium.
What papillary muscle surrounds the pericardial sac?
There are papillary muscles IN the ventricles of the heart which keep the tricuspid and the mitral valves (AV valves) closed.
What are the small muscle masses attached to the chordae tendineae?
papillary muscles
What is the significant name for heart muscle?
cardiac muscle. a type of cardiac muscle is the papillary muscles attach to the lower portion of the interior wall of the ventricles. They connect to the chordae tendineae, which attach to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle. The contraction of the papillary muscles opens these valves. When the papillary muscles relax, the valves close.
