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.

Atrioventricular node at the bottom of the?
The heart beats regularly because it has it's own pacemaker. The pacemaker is a small region of muscle called the sinoatrial, or SA, node. It is in the upper back wall of the right atrium. The node triggers an impulse that causes both atrium to contract. Very quickly, the impulse reaches the atrioventricular, or AV, node at the bottom of the right atrium. Immediately, the atrioventricular node triggers an impulse that causes both ventricles to contract.
What is the function of satellite cells?
Basically for muscle regeneration
Does heart muscle has the same structure as the arm muscle?
No heart muscles are different from arm muscles. They are not same either structure vise or by function wise , both have seperate entity and function.
Where does the atria located?
The Heart's own pace makerThe heart beats regularly because it has it's own pacemaker. The pacemaker is a small region of muscle called the sinoatrial, or SA, node. It is in the upper back wall of the right atrium. The node triggers an impulse that causes both atrium to contract. Very quickly, the impulse reaches the atrioventricular, or AV, node at the bottom of the right atrium. Immediately, the atrioventricular node triggers an impulse that causes both ventricles to contract.
The stage of the heart cycle in which the heart muscle contacts and the chambers pump blood?
The sinoatrial node depolarizes the atria and causes them to contract which tops up the ventricles with blood, the signal then moves through the atrioventricular node and then the atrioventricular bundle and into the purkinje fibres which causes the ventricles to depolarize and contract sending blood from the right ventricle to the lungs and from the left ventricle. The Atria repolarizes at the same time as the ventricles depolarize and then a fraction of a second later the ventricles repolarize and the cycle begins again.
The structure and function of right atrium?
The structure of the right atrium is to send blood through an atrioventricular valve to the right ventricle and it's structure is mostly muscle and tissue.
What delays the electrical impulses for the muscle to contract?
Atrioventricular (AV) node
What is the role of papillary muscle?
The papillary muscles are muscles located in the ventricles of the heart. The role of the papillary muscle is to prevent inversion or prolapse or the atrioventricular valves.
Specialized muscle fibers connecting the upper and lower heart chambers?
atrioventricular bundle
Name the structure found between the atrioventricular valve and the papillary muscle?
interventricular septum
What prevents the atrioventricular valve from being pushed into the artium when the ventricle contracts?
The papillary muscle.
The flaps of the atrioventricular valves are held in place by the tough fibrous what?
chordae tendinae
Is it correct to say the function of muscle cells is to give shape to the body?
No. While the shape of your body does depend on your muscles, it is not their function. Muscles regulate movement and posture. If anything the skeletal system retains structure.
Does the cerebellum regulate muscle tone?
yes
What tissue's major function is to contract?
The muscle tissue's main function is to contract.
What are the small muscle masses attached to the chordae tendineae?
papillary muscles
What are the main function of the muscle?
the muscle are to move the bone.
