The Pacemaker cells of the Sinoatrial Node spontaneously initiates the impulse. Without stimulation from nerve fibers or any other outside agents, the nodal cells initiate impulses that spread into the surrounding myocardium and stimulate cardiac muscle fibers to contract.

What are myogenic cells?
A myogenic heart is a heart that can naturally contract and relax and doesn't need to receive impulses from a nerve to make it contract. your heart is a Myogenic heart
What is the difference between myogenic and neurogenic muscle?
The myogenic heart refers to the contractile part of it, while the neurogenic heart refers to the highly specialized muscle cells that no longer contract but instead conduct impulses in the heart.
Impulses for the sense of taste travel to this lobe?
Impulses for the sense of taste travel to the parietal lobe of the brain. The parietal lobe is responsible for processing sensory information and integrating it with other sensory inputs. It helps us perceive and interpret the taste sensations we experience.
What cells transmit and receive impulses?
nervous tissue.
The most rapid nerve impulses are impulses that are carried?
no
Explain the source of signals detected by the electromyogram electrodes?
muscle fibers produce and conduct their own impulses and their conducting of impulses result in voltage differences that can be detected by electrodes.
Impulses that are carried to the heart by means of the vagus nerve are?
Parasympathetic impulses and cause the heart rate to decrease.
Impulses carried to the heart by means of fibers that secrete acetylcholine are what?
parasympathetic impulses and cause the heart rate to decrease
From the time a tactile stimulus is detected by a receptor in the foot to the time the resulting nerve impulses arrive in the postcentral gyrus of the brain the impulses will have traveled over?
three
What is the medical term meaning interruption of the electrical impulses in the heart's conduction system?
Heart block is the term meaning interruption of electrical impulses in the heart's conduction system.
What is the interruption of these impulses in the heart's conduction system?
Interruption of the impulses in the heart's conduction system is known as heart block. Heart block may be caused by scar tissue from a heart attack, among other things.
What does somatic nervous system take impulses to?
the heart
How does the human heart operate?
Human heart is myogenic in nature. It consists of sinoatrial node in the right atrium below the endodermis. this node initiates the electrical impulses in heart. As it is initiator it is also called pacemaker of heart. The atrioventricular node gathers the impulses and transmits them to the purkinje fibres via. bundle of his-tawara. As atrioventricular node collects all the impulses it is also called pacesetter of heart.
What creates the electrical signal in your heart?
neural impulses from the brain
How is the pace maker involved in your heart beat?
The pace maker uses electrical impulses to regulate heart rate. It is used when the bodies own impulses from the brain are not able to do the job anymore.
How would a nerve carrying impulses from your brain to your eyelids be different to one carrying impulses to your heart?
The nerve is the perfect female orgasim.
What impulses does a cardiac pacemaker use?
A cardiac pacemaker uses electric impulses to regulate a beating heart. Cardiac pacemakers are designed to treat various forms of arrhythmia (heart beat irregularities).
