What is impulse conduction is fastest in neurons?
Impulses that travel along myelinated neurons are the fastest.
Why would a lack of neurotransmitters change the function of the brain?
signals travel from neuron to neuron through neurotranmitters
Is a minute gap between a neuron and target cell across which neurotransmitters travel?
Synaptic cleft
What happens in the synapses?
An action potential (or impulse, if you like) reaches the "presynaptic knob". This causes calcium gates in the membrane to open, and an there is an influx of calcium ions into the axon. this causes vesicles (like little sacks) containing transmitter substance, to move towards, and fuse with, the synaptic membrane. this causes the transmitter substance to diffuse across the membrane, where it combines with specfic receptor proteins on the post synaptic membrane. These cause an increased permeability in the membrane to sodium ions, and these rush in. if the threshold value was reached, the influx of NA+ ions will be sufficient to cause an action potential / impulse, and the impulse will travel down the axon.

What is released when an impulse reaches the end of a neuron?
The impulse ends in the terminal or synaptic knob. Here neurotransmitters are put in vesicles and travel across the synaptic cleft to the next neuron.
Where do impulses travel?
Nerve impulses travel up through nerves, into the spinal cord and into one of the different lobes of the brain depending on where the impulse comes from. For example, if the impulse comes from your ear, the impulse would travel to the temporal lobe.
How does a message. travel across the gap. at a synapse?
it is sent through the neurotransmittersAt the synaptic terminal an electrical impulse will trigger the migration of vesicles containing neurotransmitters toward the presynaptic membrane.
What is the result of sodium ions moving across the axons membrane during an action potential?
a neural impulse(electrical impulse) is released and it travels down the axon of a neuron to the axon terminals. At the axon terminal there are sacs called synaptic vesicles which contain chemicals called neurotransmitters. When the neural impulse reaches the terminal it causes the sacs to move closer to the membrane of the axon terminal and release the neurotransmitters inside. Then neurotransmitters travel across the synaptic gap and stimulate the dendrites of another neuron and the whole process starts again.
What does hormones and neurotransmitters not have in common?
They are both from different systems. Hormones are from the endocrine system and neurotransmitters are from the nervous system. They both also have different ways of how they communicate with the body to change or have a reaction. Hormones travel through the blood to the location that needs to be changed or balanced. Neurotransmitters travel along nerves. A third thing is that they affect the body differently. Hormones affect the systems that we generally don't notice, like our growth. Whereas neurotransmitters our typically immediately noticed, like tickling or pain.
What chemicals are released when a nerve impulse arrives at the synapse?
Neurotransmitters. There are several hundred different neurotransmitters used by different types of nerves in different parts of the body, a few are:acetylcholinedopamineserotoninglutamateaspartateD-serineγ-aminobutyric acid (GABA)glycinenitric oxide (NO)carbon monoxide (CO)hydrogen sulfide (H2S)norepinephrineepinephrine (adrenaline)histaminephenethylamineN-methylphenethylaminetyramine3-iodothyronamineoctopaminetryptaminesomatostatinsubstance Pcocaine and amphetamine regulated transcript, opioid peptides[9]adenosine triphosphate (ATP)adenosineanandamideβ-endorphinvasopressindynorphinoxytocinetc.
What is Regulatory Bodies in travel and tourism?
compare and contrast the roles of the different trade and regulatory bodies in the UK
Neurotransmitters are chemical messengers that travel across the?
synaptic gap
Do Signals travel along nerves in the form of rapidly diffusing neurotransmitters?
yes bcoz of myelin sheaths on the neurons .. they help the signal to move by jumping ... so that it moves faster with the help of neurotransmitters like acetyl choline .which helps in fast coduction of nerve impulse ..they r found generally at nerve endings to transfer the signal from 1 neuron to other.
Where do nerve impulses travel?
Nerve impulses travel up through nerves, into the spinal cord and into one of the different lobes of the brain depending on where the impulse comes from. For example, if the impulse comes from your ear, the impulse would travel to the temporal lobe.
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.
