The nurse is explaining the workings of selective serotonin reuptake inhibitors to a client with a diagnosis of depression. within the teaching, the nurse mentions that in the nervous system, the transmission of information by neurotransmitters is:

Synaptic signaling is the answer.  It is the same to paracrine signaling but there is a something different in structure called the synapse between the two cell originating and the receiving the signal for example between a neuron and the muscle that is controlled by neural activity. It only happens between cells with synapse. 

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

is this a question? wassup
