BOTANY

Detailed explanation-1: -Neurons are born in areas of the brain that are rich in concentrations of neural precursor cells (also called neural stem cells). These cells have the potential to generate most, if not all, of the different types of neurons and glia found in the brain.

Detailed explanation-2: -Neuron or a nerve cell looks like a star-shaped cell with a tail. Neurons are the basic units of the nervous system and its most important part is the brain. Every neuron is made of a cell body (also called a soma), dendrites and an axon.

Detailed explanation-3: -Nerve cells are shaped like long wires so they can carry messages form one end of the body to the other. Some nerve cells in the brain can keep their information and send out messages for a long time. This is how we learn and have memory.

Detailed explanation-4: -Star-like cells called astrocytes diligently fill in the gaps between neural nets, each wrapping itself around thousands of neuronal connections called synapses. This arrangement gives each individual astrocyte an intricate, sponge-like structure.
