No, ventricular systole refers to the contraction of the ventricles in the heart. Nerve impulses originate from specialized cells called neurons in the nervous system. These impulses are responsible for transmitting signals throughout the body, including to the heart to regulate its activity.

How does an impulse cross a synape?
When an impulse reaches the end of a neuron (presynaptic terminal), it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, causing a change in its membrane potential, which leads to the propagation of the impulse across the synapse.
What is the sequence of events that correlates to the sequence of events of a nerve impulse?
2,1,3,4
What carry the impulses from the ear to the brain?
The impulses from the ear are carried to the brain by the auditory nerve, also known as the eighth cranial nerve or vestibulocochlear nerve. This nerve is responsible for transmitting sound and balance information from the inner ear to the brainstem.
What carries the nerve impulse from the central nervous system to an effector?
Nerve impulses are carried from the central nervous system to the effector organs (muscles or glands) by motor neurons. These motor neurons form a pathway known as the efferent pathway.
What is The part of the eye that converts light energy to electricity into electricity signals?
First you must understand how light is transferred into an image by the eye. Located in the retina at the back of the eye are millions of photoreceptors. The way I understand them to work is they are constantly blocking any impules from themselves to the next connection, ganglions. When light hits these potoreceptors, the impulse is released, travels through the ganglion, and then is transmitted to the actual optic nerve. So according to this question, the photoreceptors are the trigger of light to impulse, but the answer to your question is the ganglion that transmitts the impulse to the optic nerve.
What is responsible for transmission of nerve impulse across a synapse?
NEUROTRANSMITTER is responsible for transmission of nerve impulses.Eg.dopamine,acetylcholine etc.
Which part of the neuron is responsible for generating a nerve impulse?
The axon is responsible for generating and transmitting a nerve impulse. It is a long, slender projection of the neuron that carries the electrical signal away from the cell body towards other neurons or muscles.
What is quicker a nerve impulse or a hormone?
nerve impulse
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
How does a nerve impulse follow all or nothing principle?
How does a nerve impulse follow the all-or-nothing principle???
What pathway does a nerve impulse follow after initiated into a receptor?
nerve my a$$ nerve
Is an action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
Is a action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
What is a nerve impule transmitted by axons?
It is called a nerve impulse.
The neurotransmitters of a neutron enable a nerve impulse to do what?
Neurotransmitters in a neuron allow a nerve impulse to be transmitted from one neuron to another by crossing the synapse and binding to receptors on the receiving neuron. This triggers an electrical or chemical signal to continue the nerve impulse along the neural pathway.
What nerve receive the impulse?
receptors.
What is the difference between synaptic and nerve impulse transmission?
Synaptic transmission is chemical, while nerve impulse or axonal transmission is electrical.
