Getting to see and investigate the creatures of the past
Answer:
option B) is correct
Explanation:
The all or none response means that if a muscle contracts, it will contract completely. Thus implying the all or none law which states:
The potential of a response of a muscle fiber or nerve cell is independent of the potential of the stimulus. If a stimulus is more than a certain critical value it will trigger muscle fiber or a nerve. Most importantly resulting in either an all-or-none response thus reducing possibility of any information loss.

1. Glial cells are refereed to as forgotten cells because the number of scientific research carried out on glial cells is very small compared to the other nerve cells. The other nerve cells in the nervous system have been focus of research for years, this is done in order to better understand human brain; but the glial cells have not receive that same kind of attention from researchers.
2. The following differences exist between neurons ans glial cells:
a. Glia cells has only one process while neurons have two processes, which are axon and dendrites.
b. Glial cells can not generate action potentials while neurons can.
c. Neuron have resting potential; glia cells do not.
d. Neurons possess chemical synapses which use neurotransmitters. Glial cells do not possess chemical synapses.
e. The glial cells in the nervous system are much more in number than the neurons.
3. If the glial cells stop functioning in a human being, the entire nervous system will start to malfunctioning. This is because the roles that the glial cells play in the nervous system are very important ones that are very necessary for the overall functioning of the nervous system.
