What travels through the neuron?
An electrical impulse will travel through a neuron.
What does communication in the nervous system depend on which are electrical impulses that travel from neuron to neuron?
action potentials
What is Diffusion of transmitters across synaptic cleft?
It is when neurotransmitters are released form one neuron and travel across the synapse, which is a gap between two neuron, in order to stimulate the second neuron
What does the sheath do in the nerve cell?
The myelin sheath acts as a covering on the axon of a neuron just as the covering on the cord you plug into an electrical socket. If it is damaged, the current can be "short circuited" and the neuron and the axon will not function. This sheath allows impulses to travel rapidly. MS is a disease where these sheaths are damaged.
Laws governing neuron?
all or nothing law - states that it is either that neuron reacts or not at all but if it does react, it reacts with fullest strength law of dynamic polarity - states that nerve impulses travel only in one direction from neuron to neuron

What is a neuron identify the parts of the neuron and their functions?
there's the axon (the nerve) the electrical impulse goes down that and covering the axon is the myelin sheath, otherwise known as a fatty sheath which insulates and helps make the electrical impulse go faster. In between each myelin sheath there are synapses (gaps between each one) and the impulse has to cross the gap so neurotransmitters are released which bind to receptors on the other side creating another electrical impulse which makes it travel even faster.
Communication within a neuron is electrical while communication between neurons is chemical.?
Yes, that's correct. Within a neuron, communication occurs through electrical signals that travel along the neuron's axon. When these signals reach the synapse (junction between neurons), they trigger the release of chemical neurotransmitters that carry the signal to the next neuron.
How does a signal cross from the axon of the neuron to the receiving cell?
When the electrical signal reaches the end of an axon, neurotransmitters are released. They travel across the synapse. Once they reach the receiving cell, they create a new electrical signal.
How does a signal crosses from the axon of a neuron to a receiving cell?
When the electrical signal reaches the end of an axon, neurotransmitters are released. They travel acrross the synapse. Once they reach the receiving cell, they create a new electrical signal.
What are the two elements needed for neural communication to happen?
Neural communication requires an electrical signal to travel down the axon of a neuron, which is generated by changes in ion concentrations across the cell membrane. At the synapse, neurotransmitters are released from the presynaptic neuron and received by receptors on the postsynaptic neuron to transmit the signal.
What is the function of the dentrites?
Dendrites are attaches to the axon terminals of other neurons. The nerve impulse travel from other neurons into the corresponding neuron via dendrites.
How neurone work?
Neurons carry messages by converting a chemical signal into an electrical one, and vice versa. The dendrites of the neuron receive "messages" from chemicals that were released by another neuron. These chemicals are called "neurotransmitters". The neurotransmitter stimulates the neuron to depolarize. This means that the neuron's cell membrane becomes more permeable to sodium, and sodium moves into the cell. This causes the electrical charge of the cell to change, because sodium is positively charged. When it moves into the cell, the inside of the cell (or neuron) becomes less negatively charged and more neutral. At the same time, the area outside the cell becomes more negatively charged because of the positive sodium ions leaving that space. This rapid change in electrical charge is called "depolarization" and is essentially an electrical impulse. If the electrical charge is drastic enough (i.e., it meets the "threshold potential" by changing by at least 15 to 20 millivolts) the electrical signal carries all the way down the neuron into the axon. In the axon, a myelin sheath, or fatty covering, covers the neuron and essentially acts as insulation so that the electrical impulse can travel more quickly. Once the impulse reaches the axon terminal, it signals neurotransmitters to be released from that neuron and be interpreted by another neuron. Hence, the process starts all over again. I apologize for this answer being so long, there really is no way to answer this question briefly.

Are motor neurons an electrical synapse?
no,motor neurons are not electrical synapse but are normal nerve cells.they help in transmission of electrical impulses from the site of stimulus towards the spinal cord.the impulses have to travel and cross certain spaces or junctions between two consecutive nerves,the axon bulb of one to dendrites of next neuron.
What is Diffusion of transmitters across synaptic cleft?
It is when neurotransmitters are released form one neuron and travel across the synapse, which is a gap between two neuron, in order to stimulate the second neuron
