Which structure in a neuron helps to conduct a nerve impulse away from the cell body?

The axon of a neuron conducts electrical impulses away from the cell body. This is easy to remember because axon starts with an "a" for away.

Is Serotonin related to the modulation of mood and impulse control?
Yes, serotonin is related to the modulation of mood and impulse control. It is a hormone manufactured by the brain that helps control the impulse and various moods.
What part in the nervous system moves?
Its the impulses sended from neuron to neuron via synapses... it can travel within a fraction of second which helps us to escape from dangers rapidly...
What about the diameter of the nerve fiber?
The smallest neuron is at .004mm. The longest neuron, which runs from the lower spinal cord to the big toe, is over a meter long!
When the action potential reaches the terminal end of the pre-synaptic neuron how does it continue?
the impulse is transmitted by either neurons or sensory or effector organs.impulse is nothing but the stimulation for an part of body to carry out specific actions.generally impulses are transmitted very faster by neurons that too mylenated neurons.when an impulse is transmitted across a neuron or organ it gets polarised.due to unknown mechanism the axon terminals present at the end of axon release special type of transmitters called neurotransmitters into the gap present in between 2 neurons or a neuron and organ.these examples of neurotransmitters are GABA,acetylcholase,epinephrine ,nor epinephrine etc.these help in transmitting impulses from one to another.these get diffused into gap from axon terminals and helps in transmission.after the impulse is transmitted these again gets inactivated or taken back into axon terminals.these are inactivated by special enzymes.hence these are very important in nervous system for impulse transmission .
What does a dendrite look like?
The nerve cell/neuron has braches called dendrites coming off of it, these dendrites are long and are able to cling on to other cells and make it easier. Hope this helps!!!
Which of the following helps carry nerve impulses across the synapse?
neurotransmitter carries the nerve impulses from neuron to neuron across a synapse
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.
What is the value of the connective nerve tissue wrapping found in nerve?
The myilen sheath helps conduct the nerve impulse kind of like water and electricity.
What is the adaptive features of neurone on the central nervous system?
the neuron consist of the million short dendrites that receive electric impulse to the body cell, also the long axon that takes away the electric impulse away from the cell body and also it contain the myelin sheath that helps in contraction on axon to facilitate the quick transmission of the nerve impulse
What cell maintains homeostasis?
Homeostasis requires many different types of cells but the main cell that ensures that homeostasis is maintained is the nerve cell which forms your sensory neuron this helps by sending a nerve impulse to the hypothalamus of your brain or the islets of langerhan in the pancreas this nerve impulse helps send a message to the stated parts of your body telling them to take corrective measures to stabilize your body's internal environment
What is synapses?
A synapse is a small gap at the end of a neuron that allows information to pass from one neuron to the next.
Does glucose conduct?
No it does not conduct electricity, hope this helps x ;)

Does a Neuron perform photosynthesis?
No a neuron doesn't perform photosynthesis because it is a part of a nerve which helps to send ssignals to let your brain know whats going on with your body.
What about the diameter of the nerve fiber?
The smallest neuron is at .004mm. The longest neuron, which runs from the lower spinal cord to the big toe, is over a meter long!
