Melanie mixes 15ml of it with 90ml of water and applies it directly to dry hair. Annabel's hair before the Olaplex treatment. Her hair is coloured and 'tortured by sun, chlorine and over-enthusiastic use of straighteners', so she is keen to see whether Olaplex works the wonders it promises.
The nervous system is built from two broad categories of cells, neurones and glial cells. The glial cells outnumber the neurones and the two cell types occupy a comparable amount of space in nervous tissue.The main glial cell types are, in the central nervous system, astrocytes and oligodendrocytes and, in the peripheral nervous system, Schwann cells, enteric glial cells and satellite cells.lia also maintain appropriate concentrations of ions and neurotransmitters in the neuronal environment. Increasing body of evidence indicates that glial cells are essential regulators of the formation, maintenance and function of synapses, the key functional unit of the nervous system.
Another type of glial cell in the central nervous system are oligodendrocytes, which creates myelin sheaths around the axons of neurons. The myelin sheath helps your neurons conduct signals more quickly between one another and other cells. Finally, star-shaped glial cells in the CNS are collectively known as astrocytes.n more detailed terms, neuroglia are cells in your nervous system that are not neurons. Their role is to be the support team and cheerleaders for the neurons. The neuroglia: 1  Form myelin, which wraps around axons to speed up electric impulse conduction.
