Nerve impulses, which are electrical, do not jump across the synaptic gap at synapses. Instead, the arrival of a nerve impulse at the axon terminal triggers the release of chemicals called neurotransmitters from the axon terminal into the synaptic gap, the nerve impulses then travel across the chemicals to the place where it needs to go to

When an action potential passes over the surface of synaptic knob the contents of vesicles is released in the presence of?
When an action potential reaches the synaptic knob, calcium ions rush into the neuron. This influx of calcium triggers the fusion of synaptic vesicles with the presynaptic membrane, leading to the release of neurotransmitters into the synaptic cleft. The neurotransmitters can then bind to receptors on the postsynaptic neuron, influencing its activity.
What is the space through which a nerve impulse passes from one nerve cell to another called?
The space through which a nerve impulse passes from one nerve cell to another is called a synapse. It is a small gap between neurons where neurotransmitters are released to transmit signals between the cells.
Which is the last part of the neuron to be involved in the transmission of a neural impulse towards the next neuron?
Signalling ALONG a neuron is electrical, but signalling BETWEEN neurons is a chemical process. Neuron A 'passes' a message onto the next by releasing chemicals called neurotransmitters , which are then taken up by neuron B. The point at which these neurotransmitters are released from the neuron A is called the 'terminal bouton' and is the end of its axon. More specifically, it is the presynaptic membrane OF the terminal bouton at which the passing on of a message occurs.
How does information pass from one neuron to another?
Information passes from one neuron to another through a process called synaptic transmission. When an action potential reaches the end of one neuron, it triggers the release of neurotransmitters into the synaptic gap. These neurotransmitters bind to receptors on the neighboring neuron, leading to the generation of a new action potential in the receiving neuron.
What passes from the neuron to the muscle cells and what effect does it produce?
Neurotransmitters pass from the neuron to the muscle cells, leading to muscle contraction. This process is known as synaptic transmission, where the release of neurotransmitters triggers a response in the muscle cells by activating receptors on the muscle cell membrane, leading to muscle contraction.
What is it called when a message passes though a neuron?

What is the structure or gap called where one neuron can pass a signal to another neuron or cell?
The structure where one neuron passes a signal to another neuron or cell is called a synapse. It consists of a small gap known as the synaptic cleft, where neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron, facilitating communication between the two.

What happens to neurotransmitters after the never impules passed through the synapse?
After a nerve impulse passes through the synapse, neurotransmitters are released into the synaptic cleft and bind to receptors on the postsynaptic neuron, transmitting the signal. Once their job is done, neurotransmitters are typically cleared from the synaptic cleft through reuptake into the presynaptic neuron, enzymatic degradation, or diffusion away from the synapse. This process ensures that the signal is brief and allows the neurons to reset for the next impulse.
What is the connection between the adjacent neurons?
Neurons connect with each other at synapses. That is the principal means by which they communicate. One major form of connection is the release of molecules of neurotransmitter from the sender neuron to the receiver neuron. These molecules can change the voltage potential at the receiving neuron, making it more or less likely to fire.
Do neurons touch each other?
Not exactly; as an impulse moves from one neuron to another it crosses a small space between the neurons called a synapse. The neurons as said to 'not touch' because the cell MEMBRANES of the two neurons do NOT touch, nor merge, nor consequently is there any sharing of cytoplasm between the two neurons. The two neurons ARE, however, HELD TOGETHER at that synapse by small molecules called SYNAPTIC ADHESION MOLECULES, which protrude FROM each neuron into the synaptic cleft or gap and then stick to one another. In this sense, PARTS of neurons do 'touch' PARTS of other neurons, in a MECHANICAL or structural manner, but NOT in an electrical or signal sense. The neural SIGNAL passes through the synaptic cleft or gap via neurotransmitter chemicals which are released by one neuron, diffuse quickly through the gap, and then stimulate a signal in the receiving neuron.
State the three main parts of a neuron and describe how an impulse travels through a neuron?
Okay, information is received through the dendrites, and then moves on the the cell body. From there, the cell's axon passes the message on to other neurons or to muscles or glands.
What is the name of a neuron that transmits neural impulse from the sensory neuron to the motor neuron?
A relay neurone passes impulses from a sensory neurone to a motor neurone.
