Which ion causes neurotransmitter vesicles to fuse with the axon's membrane during the conduction of a nerve impulse from one neuron to the next?
calcium
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
Is it correct that synaptic clefts prevents an impulse from being transmitted directly from one neuron to another?
Yes, that is correct. The synaptic cleft is a small gap between neurons, and it prevents direct transmission of impulses. When an impulse reaches the end of a neuron, it triggers the release of chemical messengers called neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the adjacent neuron, allowing the impulse to be transmitted indirectly.
What are the sources of stimulation that start a nerve impulse?
An impulse begins when a neuron is stimulated by another neuron or by the environment.
What happens at the synapse between two neuron?
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.
What is a neuron impulse?
it is neuron impulse
What is the pathway of an impulse in a reflex arc?
Sensory receptor, sensory neuron, interneuron, motor neuron, and muscle.
Which ion causes neurotransmitter vesicles to fuse with the axon's membrane during the conduction of a nerve impulse from one neuron to the next?
calcium
What is the myelin sheath's function?
The function of the myelin sheath is to insulate the axon of the neuron. When there are gaps in the sheath, known as nodes of Ranvier, the nerve impulse can jump from gap to gap, thus increasing greatly the speed of conduction of the nerve impulse. This is known as saltatory conduction.

What part of a nerve cell carries impulses toward the cell body?
There is one way conduction of impulse into the neuron, from dendrites to nerve body to axon.
Which ions causes neurotransmitter vesicles to fuse with the axons membrane during the conduction of a nerve impulse from one neuron to the next?
I believe it's Na+

Why would a neuron not send an impulse?
If a neuron is not sending out an impulse or signal, this means the neuron is at rest. Neurons send signals electrochemically.
