NURS 6630 MIDTERM EXAM STUDY GUIDE • Non-compliant patients • Neurotransmitters- are chemical messengers that allow signals to cross synapses to transmit information from a nerve cell or neuron to a target cell. Nerve transmitters coordinate behavor by stiulating an action or inhibiting an impulse. Example of neurotransmitters: dopamine. Used by the brain to help regulate breathing, heartbeat, and digestion. It can also affect concentration, sleep, and mood. • Neurons- have many sizes, lengths, and shapes that determine their function based on where they are in the brain; and are the cells of chemical communication in the brain. Human brains are comprised of tens of billions of neurons, and each is linked to thousands of other neurons. Thus, the brain has trillions of specialized connections known as synapses. * The anatomically addressed brain is thus a complex wiring diagram, ferrying electrical impulses to wherever the “wire” is plugged in (synapses). **When neurons malfunction behavioral symptoms may occur. When drugs alter neuronal function, behavioral symptoms may be relieved, worsened, or produced. Neurons are some of the longest-lived cells in your body; neurons are irreplaceable, and neurons have huge appetites (glucose and appetites). Neurons transit signals when stimulated by sensory input or triggered by neighboring neurons. • Gene Expression • Cytochrome P450 Enzyme System
