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.
One population, called hematopoietic stem cells, forms all the types of blood cells in the body. A second population, called bone marrow stromal stem cells (also called mesenchymal stem cells, or skeletal stem cells by some), were discovered a few years later. BAMMMM!!!
The action of inverting something or the state of being inverted
Answer:
To be sustainable is to be able to maintained at a certain rate. It's to keep things continuous and viable. For example, wind energy is sustainable compared to oil because wind is easier to get than oil. Another example is if a country only has about 10-13 crimes a year for 20 years, crime is sustainable in that country.
