How do neurotransmitters work? - ANSWER Once it crosses the gap, it is taken up by the post- synaptic receptor, i.e. the dendrite of the next neuron. The chemical message is converted back into an electrical impulse and the process of transmission begins again. Each one has its own specific molecular structure that fits perfectly into a post-synaptic receptor site, like a lock and key. Why do neurotransmitters work with receptors in the brain - ANSWER to influence and regulate a range of ...

what does grey matter consist of? cerebellum, cerebrum, brainstem, butterfly shaped portion of the central spinal cord What is grey matter associated with? learning (changes linked to alzheimer's, schizphrenia, MDD) what is white matter? nerve fibers that connect neurons from different regions into functional circuit "transit system" what is white matter associated with? sensory and motor function, cognition (changes in white matter associated with autism and vascular dementia)

Prefrontal Cortex Symptoms of MDD - ANSWER Concentration Mental Fatigue Mood PFC & Amygdala Symptoms of MDD - ANSWER Guilt Suicidality Worthlessness

How does reviewing the genetic makeup of a client help guide the PMHNP in selecting medication for clients? - ANSWER Genetic testing can assist by providing more information on how clients may respond to certain psychotropic medications, as well as providing information on how a client may break down and metabolize medications based on the cytochrome P450 system. There may be an environmental exposure that turned a gene "on" that should have been "off" for one twin to develop schizophr...

Nerve fibers that connect neurons from different regions into functional circuits. Transit system. Damage to myelin impairs sensory and motor function, and cognition. Autism and vascular dementia - ANSWER white matter Cerebellum, cerebrum, brain stem, and butterfly shaped portion of spinal cord, gray matter contains neural cell bodies, axon terminals, dendrites, and all nerve synapses, associated w/learning, changes are linked to Alzheimer's,schizo, and mdd - ANSWER gray matter separates ...
