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.
Like neurons, glial cells are composed of cell bodies and cell processes. (Note: Glial processes are visible only in special stained preparations, such as a Golgi stain.) Three major types of neuroglial cells are recognized in the central nervous system: (a) astrocytes -- provide structural support for the CNS.; (b) oligodendroglia -- form myelin in the CNS, and. (c) microglia -- serve as a macrophage in the CNS.
