How does a message jump across the synaptic gap and passes to the next neuron?

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

At the synaptic terminal an electrical impulse will trigger the migration of vesicles containing neurotransmitters toward the presynaptic membrane.

What is the space through which a nerve impulse passes from one nerve cell to another called?
A nerve impulse passes from an axon terminal of one neuron to another neuron across a synaptic gap.
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 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.
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.
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.

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.
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.
What passes from the neuron to the muscle cells and what effect does it produce?
Acetylcholine (ACh) is the neurotransmitter that passes from neuron to muscle cells and it causes the Na/K channels to open allowing Na+ to flow into the cell triggering an action potential.
Light sensitive worker needed to receive visual images and transmit impules to the brain?
the image passes from neuron to neuron through neurotransmitters until it reaches the brain, where the neurotransmitters are read

What kind of neuron sends a message from the brain to the muscles in a persons arm to control the movement involved in putting clothes on?
There are basically two kinds of neurons- sensory and motor. Motor neurons are responsible for passing on messages from the brain, to the effector muscles, while performing a voluntary action (they also do that for involuntary actions) Sensory neurons on the other hand, detect a stimulus, and pass on the message to the brain, which analyses the information, decides the course of action, and passes on the message back through the motor neuron, to the effector muscles.
What is an axon-terminal?
An axon terminal is the structure of a neuron (a single cell of the central or peripheral nervous system) at the end of it's axon that forms a synapse with another neuron. Generally, the axon terminal is the point at which a neuron passes information to the neurons with which it is connected.
