A chemical found in the synaptic vesicles which, when released, has an effect on the next cell is called a ________.

A) glial cell
B) neurotransmitter
C) precursor cell
D) synapse

A chemical found in the synaptic vesicles which, when released and has an effect on the next cell is called a neurotransmitter. Glial cells are non-neuronal cells that provide support and protection for neurons. Precursor cells are immature cells that have the potential to become specialized cells, but they are not involved in neurotransmission. Synapse is the junction between two neurons or between a neuron and a target cell where neurotransmitters are released.
