A Pap test, also called a Pap smear, is an exam a doctor uses to test for cervical cancer in women. It can also reveal changes in your cervical cells that may turn into cancer later.
Neurotransmitters A Neuron is a specialized nerve cell that receives, processes, and transmits information to other cells in the body. We have a fixed number of neurons, which means they do not regenerate.
Neurotransmitters are molecules that nerve cells, or neurons, use to communicate. When electrically stimulated, the transmitting, or prensynatptic, neuron releases neurotransmitters into the gap, called a synapse, between itself and an adjacent neuron.hey are distinguished from inhibitory neurotransmitters, which make an action potential in the cell less likely. The most common excitatory neurotransmitter in all vertebrates, including human beings, is called glutamate.
