How does an insect's heart beat?
An insect's heart is a tube-like structure that runs along the insect's back and pulsates to pump hemolymph (insect blood) through its body. Contractions of muscles surrounding the heart cause it to beat and circulate nutrient-rich hemolymph to the insect's tissues.

What is myogenic heart?
So the word "myogenic" refers to a type of cell, a myocyte, that is able to contract by itself, without any nerve stimulation (aka signals from the brain). So if someone refers to a myogenic heart, that person just means that the heart is able to beat on its own, without you willing it to beat. The myocytes within the heart regulate the heart's contractions instead of your brain doing it.
Is Human heart is myogenic or neurogenic?
In the human heart, contraction is initiated by a special modified heart muscle known as sinoatrial node. It is located in the right atrium. The SA node has the inherent power of generating a wave of contraction and controlling the heart beat. Hence, it is known as the pacemaker. Since the heart beat is initiated by the SA node and the impulse of contraction originates in the heart itself, the human heart is termed myogenic. The hearts of vertebrates and molluscs are also myogenic.
What type of muscle is a heart?
The heart or "Cardiac muscle" is myogenic meaning that it will independently contract without a stimulus. The nerve impulses in the heart are merely to regulate the natural beat of the heart.
What controls your heartbeat?
The heart is not controlled by anything, it is a myogenic muscle which means if you were to remove the heart from the body it would continue to beat. However, the adrenal medulla is the part of the brain responsible for the release of adrenaline,when adrenaline is released, the SAN is stimulated to work faster and increases your heart rate, this happens when playing sports,or during a fight or flight response.
How fast does a heart beat when you exercise?
