Gap between nerve cells?
The gap between nerve cells is called a synapse. Neurotransmitters are released from one nerve cell into the synapse and bind to receptors on the next nerve cell, allowing communication to occur between cells. This process is essential for transferring signals throughout the nervous system.
How is a nerve specialised to carry out its function?
A nerve cell is called a neuron. The neuron has dendrites that receive impules from the previous neuron and send it to the cell body and an axon that transmits the impulse to the next neuron. There is a space between one cell's axon and the next cell's dendrites called a synapse. Neurotransmitters are released from the axon terminal to carry the impulse across the synapse.
How does the myelin sheath and synapse affect nerve impulses speed up or slow down?
The myelin sheath acts as an insulating layer that helps speed up nerve impulses by allowing them to "jump" between gaps in the sheath called nodes of Ranvier. This process, known as saltatory conduction, accelerates the transmission of nerve impulses along the axon. At the synapse, neurotransmitters are released to transmit signals between neurons. The efficiency of this process can also affect the speed of nerve impulse transmission.
Where is the signal to transferred to the association nerve cells?
The signal comes from the brain, down the spinal cord, and down to the nerve cells that need to send the stimulus signal. The signal also runs vice versa, up the spinal cord and into the brain.
What is optic nerve head pallor also called?
Optic nerve head pallor is also called optic atrophy.

Space through which a nervous impulse is transmitted from one neuron to another?
The space through which a nervous impulse is transmitted from one neuron to another is called a synapse. It is a tiny gap between the axon of one neuron and the dendrite of another, where neurotransmitters carry signals across the gap to continue the message.
How are messages carried through your nerves?
Nerve cells send electrical impulses called synapse. These electrical stimulations travel from cell to cell, up to the brain and back. Nerves also produce different types of chemicals to manipulate the synapse.
What is an axiscylinder?
An axiscylinder is another term for an axis cylinder, also known as an axon, a nerve fibre which is a long slender projection of a nerve cell, and which conducts nerve impulses away from the body of a cell to a synapse.
Which nerve is also called laborer's nerve?
Median nerve...

What can cause synapse to not function correctly?
An abnormally thin dendritic spine can yield poor neural impulse conduction; and drugs like LSD which mimic neurotransmitters may "clog" receptors & cause continued activation, I think. I suspect there could also be problems with the PRODUCTION of neurotransmitters or with the conveyance of vesicles containing NT to the synapse. Synapses are spaces or junctions between two neurons. The principle of synapse works on mechanism of neuro-transmitters and neuro-inhibitors. When a nerve impulse reaches the end of one neuron to travel to the next one, at that moment acetylcholine is produced in the synapse. Acetyl choline being a neurotransmitter helps to transmit the nerve impulse. Right after the nerve impulse has passed through the synapse, a neuroinhibitor such as cholinesterase si produced to stop the action of acetylcholine. At a particular synapse, these two chemicals are produced at a very high rate. This is how a nerve impulse works. But suppose if the production of these two chemicals is affected, the synapse will not function properly.

What is transcutaneous electrical nerve stimulation also called?
Electrical nerve stimulation
What is optic nerve head pallor also called?
Optic nerve head pallor is also called optic atrophy.
Why vagus nerve is called wandering nerve?
The tenth cranial nerve is called vagus nerve it is also called as wandering nerve.It has been called wandering nerve because of many areas it innervates. the vagus nerve wanders all the way down from the brainstem to the colon, a long wandering trek.
