The heartbeat is caused by the contraction and relaxation of the heart muscle. The heart muscle is a special kind of muscle known as cardiac muscle, which is unique as it is both striated (strong), can work without tiring, and cannot be controlled (the movement of the muscle is automatic).
Where are intercalated disc found?
Intercalated discs are found in cardiac muscle tissue, specifically at the junction between adjacent cardiomyocytes (heart muscle cells). They contain specialized structures that facilitate communication and coordination between cells, allowing for synchronized contraction of the heart.
Cardiac muscle makes up the bulk of what tissue?
The cardiac muscle tissue us referred to as the heart or myocardium.

Does Soma affect your heart How does soma affect your heart?
Well since Soma is a muscle relaxer and your heart is a muscle I'm pretty sure it would relax it by slowing it down. So your heart rate would probably drop as well as your blood pressure.
What type of muscle is the heart made off?
the heart is made out of a special type of muscle called cardiac muscle
What kind of muscle the heart?

What muscle makes the heart pump?
The heart is a muscle.
What is muscle layer of the heart?
The muscle layer of the heart is the myocardium (or cardiac muscle).
Is the heart made of smooth muscle?
The heart is a muscle so the heart is made of the cardiac muscle.
Why is the heart made mostly of muscle tissue?
The heart IS a muscle.
