Glial Cells

Non-neuronal cells in the central nervous system that support, protect, and nourish neurons, playing a key role in maintaining homeostasis.

Neurons

Specialized cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells.

Neurotransmitters

Chemical messengers that transmit signals across a chemical synapse, from one neuron to another target neuron, muscle cell, or gland cell.
