An understanding of neurotransmission and its relationship to psychiatric symptoms is foundational to the safe, effective prescribing of Our emotions & mental performance are regulated and influenced by __________________ & ________________ in the brain Behavioral symptoms may be related to malfunctioning neurons; these symptoms can be produced, worsened, or relieved by drugs such as ___________________ medications that alter neurotransmitter processes and functioning. What client factor(s) impact the effect of psychotropic medications? When prescribing psychotropic medications, what factors should the NP consider when perscribing psycotropic drugs the chemical transmission of information between neurons and their target cells. During neurotransmission, the chemicals, or neurotransmitters, are released from their transport vesicles to bind with receptor sites to perform their duties, which are __________________ or _____________ Excitatory neurotransmitters ______________ the likelihood that the neuron will fire an action potential and inhibitory neurotransmitters ______________ the likelihood that a neuron will fire an action. The neurotransmitter is then either returned and stored for future use (known as reuptake) or it is inactivated and dissolved by enzymes Neurotransmitters are chemicals released by neurons to send communication across synaptic clefts to other neurons. Many psychiatric disorders and client symptoms occur from an excess, deficiency, or imbalance of ______________because neurotransmitters impact human emotion and behavior. Drug therapy can be prescribed to target specific neurotransmitters to achieve desired outcomes. The neurotransmitters that most impact mental health can be classified into four major categories: cholinergics (acetylcholine), monoamines (norepinephrine, dopamine, serotonin, and histamine), amino acids (gamma- amino-butyric acid and glutamate), and neuropeptides. Psychotropic medications often impact neurotransmitters by either enhancing or decreasing the neurotransmitters' ability to bind to receptor sites. Read more below about neurotransmitters, their action, their impact on mental health, and enzymes that inhibit or inactive them chemicals released by neurons to send communication across synaptic clefts to other neurons. psychiatric disorders and client symptoms occur from an excess, deficiency, or imbalance of ______________ How does Psychotropic medications impact neurotransmitters I am the chief inhibitory neurotransmitter (NT).
