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.
Describe types of neurotransmitters by their function. Neurotransmitters are endogenous chemicals that transmit signals from a neuron to a target cell across a synapse. Release of neurotransmitters usually follows arrival of an action potential at the synapse, but may also follow a graded electrical potential.
