A motor neuron carries the message from the central nervous system to the effector."
This was chosen because with the aid of the diagram, the roles of the neurones were clearly defined. However, it is brief and not explicit enough because it is written in one slide.
In addition, the writer did not give any reference to a reliable source which would have been beneficial for further studies as a student.
The site is reliable because it is an educational website course. It is legible and rich in diagrams to illustrate the topic

Biga, Sierra Dawson, Amy Harwell, Robin Hopkins, Joel Kaufmann, Mike LeMaster, Philip Matern, Katie Morrison-Graham, Devon Quick, Jon Runyeon (2018) gave a precise and succint description of the Central Nervous System (CNS) and supported it with a clear and self explanatory diagram. The approach taken by the author provides the opportunity for every new nursing/medical student to understand the topic easily and the use of words were simple to understand. The site was accessible, can be trusted and reliable as it was published by  Open Oregon State, Oregon State University. However, Lindsay M. Biga,et al (2018) did not give a  broad overview and full description of the structures of the CNS (brain and spinal cord) as compared to the article by Fernando Dangond, MD(2017).
The article by Fernando Dangond, MD(2017), was very helpful and educative but lacked references.Therefore, the source(s) of the article can not be validated and proven to be from an academically appropriate source(s). However, the article was written, edited and reviewed by medical proffessionals so can be trusted.

After describing both types of actions, it further tabulates it for quick and simple understanding. However, it is more or less a webpage for students to post academic materials and so it is not of high quality.
The source of information can not be determined and so not reliable. However, the webpage is safe and frequently visited by students and a lot of medical materials has been uploaded. The writer also included a video to have a better understanding.

In addition, the writer set objectives to be met by the intended reader which is a very important aspect of learning, keynotes were defined and summaries were made for better understanding.
The source (Lumen learning) can be trusted as it is an education technology company that uses open educational resources to improve student success.
However, it looks voluminous and might discourage learners from reading.

transmission alone a neurone as its explained how an impulse travels along a neurone and that the gap on a neuron(synapse) can not transmit impulse fron one neuron to anther neuron without the help of a neurotransmitter(acetylcholine) which is a chemical messenger which then diffuses across the synapse binding with the molecule on the postsynaptic neuron there by stimulating a new nerve impulse in the neuron.It further explained how drugs like nicotine tends to affect this process as it lower the threshold for neuron activation by mimicking acetylcholine action on the post synaptic membrane due to similarity in shape.It went futher explaining  the steps involved for an impulse transmission,with a well drawn graph beginning when a membrane is at rest, a state of polarity,the neuron needs a stimulus to be excited given rise to depolarisation which occur when a threshold is reached for the sodium ion channels to open letting in more sodium ion into the neurone and futher explained how the potassium ion channels opens as the sodium ion channels closes .Potassium ion rushes out of the neuron  to balance the charge there by repolarising the membrane . It did not leave out hyperpolorisation explaining how the slow closing of the potassium channel gates,causes an overflow of potassium ion out of the neuron, given a more negative ion outside provoking the neuron to get back to its resting phase giving time for another action potential to be initiated(refactory period).
This website was chosen because it served as an academic learning site for students revision, with good diagram and graph for a good undestanding.It is reliable in protected view as it may not be tempered with by any body putting in fake materials. However, detailed used of the site requires setting up an account payment to fully ultilised the site. This may limit people who can not afford payment. However, it offers first tutorial at a reasonable price for those who are interested.
