A chemical equation expresses the net change in composition associated with a chemical reaction by showing the number of moles of reactants and products. But because each component has its own molar mass, equations also implicitly define the way in which the masses of products and reactants are related.
Comment in Cell. 2011 Sep 2;146(5):675-7. Basal synaptic transmission involves the release of neurotransmitters at individual synapses in response to a single action potential. Recent discoveries show that astrocytes modulate the activity of neuronal networks upon sustained and intense synaptic activity.strocytes are endogenous regulators of basal transmission at central synapses.

The stratum basale (basal layer, sometimes referred to as stratum germinativum) is the deepest layer of the five epidermis layers, which is the outer covering of skin in mammals.The stratum basale is a continuous layer of cells.It is often described as one cell thick, though it may in fact be two to three cells thick in glabrous (hairless) skin and hyperproliferative epidermis (from a skin disease).The stratum basale is primarily made up of basal keratinocyte stem cells, which can be considered the stem cells of the epidermis.They divide to form the keratinocytes of the stratum spinosum, which migrate superficially.he stratum basale is primarily made up of basal keratinocyte stem cells, which can be considered the stem cells of the epidermis.
