Microglia, Polydendrocytes, Ependymal cells, and the Embryonic Neural Tube

Microglia are macrophages in the brain. Macrophages are the immune cells in the blood and other parts of the body. Microglia can be activated upon neuronal damages or infections, to destroy foreign stuff or pathogens, as well as necrotic tissues. … Continue reading

Synapses, Gap Junctions, and Glia: Their Structures, Functions, and Features

Synapses are the regions between the terminal of an axon and the receptors on other cells. Neurotransmitters can bring the messages across the synapses. Synapses can be open or enclosed, large or small. Synaptic inputs can affect the neuron activities. … Continue reading

Neurotransmitters and Their Functions

There are different types of neurotransmitters. For example, glutamate (glu) is involved in the excitation of the central nervous system (CNS). Aspartate (asp) is involved in the excitation of the brain and spinal cord. Gama-aminobutyric acid (GABA) is involved in … Continue reading
