Document Summary
Stem cell can either divide into another stem cells, one dies the other other replaces the original one. Or they can divide and one becomes a progenitor cells. Neurothrophic factor (be able to differenatiate between this one and eurothropic factors) This tells us that there are differ. Signals inside the brain that will tell the cell what to become. Has not yet decided on what type of neuroblast it will become (environmental affects, and within, nurture and nature, time the cell was produced also determines what type of cell it becomes) Neurons and glia are formed and they go /migrate to specific areas. Once in the correct region they differentiate/type of neuron or glia. Formation of synapses, how it works, they form and send messages. Very important, happens quite quickly early on in development. Myolene formed by obligodentaspeeds up the transmission of neurons, happens late in the teen years.
