B) receptor; neurotransmitter\n\nThe same neurotransmitter can have different effects on different tissues. A single neurotransmitter can generally bind to a number of different receptors. These receptors are localized in specific parts of the body (e.g. there would be different receptors for a neurotransmitter in the brain than there would be in the genitals). These different receptors cause different responses when bound to neurotransmitter.

There are a number of theories, but the short answer is "nobody knows".  Could be establishment of new synapses, could be changes in receptor sensitivity, could even be new neurons stimulated to develop, but at this point, we dont have any real idea.

Hi there! As far as i know, serotonin is what we called the Happy Substance! High levels of serotonin, increase this feeling of hapiness in us. Low levels decrease this feeling. Thus, blocking the serotonin receptors in the body would lead to depression and similar effects. and increasing the subs would give an antidepressant effects. Though that is the major effect in the CNS, we can never deny the fact that it has other effects such as those effects mentioned above. Nevertheless, it is always associated in the mood changes in the body.

The quantity of neurotransmitters in the terminals is kept relatively constant and independent of nerve activity by tight regulation of neurotransmitter formation. Regulation varies among neurons and is achieved by modifying precursor uptake or the activity of enzymes involved in neurotransmitter synthesis or destruction. Stimulation or blockade of postsynaptic receptors can decrease or increase presynaptic neurotransmitter synthesis.\n\nNeurotransmitters diffuse across the synaptic cleft, bind briefly to receptors, and activate them, causing physiologic responses. Depending on the receptor, the response may be excitatory (ie, initiating a new action potential) or inhibitory (ie, inhibiting the development of a new action potential).\n\nThe neurotransmitter-receptor interaction must be terminated quickly so that the same receptors can be rapidly activated repeatedly. The neurotransmitter is quickly pumped back into the presynaptic nerve terminals by active processes (reuptake), is destroyed by enzymes near the receptors, or diffuses into the surrounding area and is destroyed.\n\nAbnormalities of neurotransmitter synthesis, storage, release, or degradation or changes in the number and affinity of receptors can affect neurotransmission and cause clinical disorders

There are lots of neurochemicals, and the ones you're interested in are called neurotransmitters...\n\nMajor ones are: gamma amino bytyric acid; serotonin; norepinephrine; dopamine.  Also involved are countless polypeptides (often only a few aminoacids long, sometimes dozens) like melanin, the endorphins, the enkephalins, the endocannabinoids and others...\n\nWe're still unravelling the signalling systems and such of the brain, and the more we learn, the more complex it gets.\n\nThe big thing you have to realize is that the most recent data indicates that it is highly probably that the brain's chemistry is what is called (mathematically) deterministic chaos.  What that means is that any single small step is totally describable, and its immediate outcome is totally predictable, but when you expand to dozens or hundreds of steps, across large areas of involvement, it gets 'way out of hand, and the error of the estimate becomes larger than the estimate.  How environmental influences affect this is really tough to analyze, given the massive complexity and the incompleteness of our data.\n\nYour question, I fear, makes a whalloping lot more sense than my ANSWER, but, well, it's the best answer I've got...

When a nerve impulse reaches a synapse, this releases signaling chemicals called neurotransmitters. These substances travel a short distance to the membrane of the next cell, where they attach to receptors. The binding of neurotransmitters to membrane receptors helps transfer electrical signals from cell to cell. \n\nReceptors are located in the membranes of the dendrites or cell bodies. One important feature of receptors is that they bind to specific types of nerve-signaling chemicals (neurotransmitters). In most cases, the binding of neurotransmitters will lead to the movement of specific molecules through the cell membrane (via a channel). This process passes the electrical (nerve) impulses. \n\nReceptor cells - receive information from the environment.\nSensory neurons - messages travel from the receptor cells through the sensory neurons to the spinal cord and brain.\nInterneurons - connect sensory neurons to the motor neurons.\nMotor neurons - messages travel from the brain and spinal cord through motor neurons to the muscles and glands\nEffector cells - cells stimulated by the motor neurons.

Both:\n\nNeurotransmitters bond to activation sites to stimulate gates to open to pass on a signal along a signal transdunction line. Then the neurotransmitters break apart and inhibit the signal from going past the synapse. However, they are mainly stimulatory, since the only way they inhibit a signal is by breaking apart. So i guess i would actually say they stimulate gates to open

Here's a good page on L-Tyrosine and it shows the full metabolic pathway.  Side effects are from large doses. I'd say try it, go slow and note how you feel. I'd also recommend a book: The Edge Effect: Achieve Total Health and Longevity with the Balanced Brain Advantage. He has a complete questionnaire that helps you pinpoint which of the four main neuro chemicals you lack: serotonin, dopamine, GABA or acytlcholine. Then he tells you how to increase (nutritional, exercises etc.)\n\n- Peace

Endocrine refers to all hormones, not just those of the pancreas.  They are made in one cell and released into the blood stream where they work on distant cells.\n\nNeurological transmissions are predominately electrical.  The neuron gets depolarized and sends an electric signal down its axon (long process of the cell) to where it will be going to  (a muscle for example).  When the electric signal reaches its destination (the end of the axon) it causes a release of a neurotransmitter from the axon (each axon only releases one type of neurotransmitter).  These transmitters diffuse to where they are going (a muscle for example) and cause a change in that cell.\n\nSome similarities are that both hormones and neurotransmitters have specific receptors for them and they both cause changes in the cells that they interact with.  Also, there are some neurotransmitters that are hormones, they are released from the end of the axon into the bloodstream and then go to distant cells to do their work.
