Respuesta :
The transmission of signals from the brain to various parts of the body requires nerve cells. It creates a complex network called the nervous system. The genome is home to a sizable amount of genetic data that controls the growth and development of neurons.
Summary:
The determination of the genome again for the mature nervous system remains incomplete because neurons must go through many mechanisms in addition to genetic regulation. In a developing embryo, gene expression and signal transduction have an impact on the initial stage of neuron development..
The survival and expansion of the neuron depend on growth factors. When neurons can't get to this place, they can't get growth factors and perish as a result of cell death programming. Due to intense competition, the embryonic neurons that are produced in half are destroyed.
A neuron can create many synapses. A neuron becomes stabilized when it starts to operate, while others become destabilized. The embryo loses about half of its synapses as it grows. Even after birth, this process continues in humans.
These steps must be finished in order to build the basic network of cells and link them to the nervous system that will be needed for the duration of life.
