Neurons are polarized cells, based on the flow of electrical signals along their membrane. Signals are received at the dendrites, are passed along the cell body, and propagate along the axon towards the target, which may be another neuron, muscle tissue, or a gland.

WebDec 15, 2016 · For half a century, the human brain was believed to contain about 100 billion neurons and one trillion glial cells, with a glia:neuron ratio of 10:1. A new counting method, the isotropic fractionator, has challenged the notion that glia outnumber neurons and revived a question that was widely thought to have been resolved. WebGlial cells, in contrast, support neurons by providing protection and maintaining homeostasis. Essential to healthy functioning neurons, glia perform a diverse range of functions, such as nutrient provision, regulation of ion concentration, mediating immune response, and the removal of cellular waste.
