Pregnant women suffering from the common cold can be reassured about the safety of short-term use of OTC cold medications. These drugs, however, should not be used indiscriminately or for extended periods of time. In addition, use should be confined to only those products that are appropriate for the symptoms.
Acetylcholine (ACh) is a common neurotransmitter secreted by a variety of neurons. It binds to two different receptors-Ionotropic (fast) nicotinic receptors and metabotropic (slow) muscarinic receptors. 1  role in central nervous system. 2  role in peripheral nervous system. 3  receptors and signaling. 4  agonists and antagonists.
Neurotransmitters and hormones are both chemical messengers, which are released from one cell and are designated to carry a signal to a target cell elsewhere in the body.When â¦ the target cell is reached, it will trigger a specific response in that cell.The major difference is that neurotransmitters are specific to nerve tissue, and travel from one neuron to the next. The target cell is the next neuron; it is a short distance which is traveled very quickly.hen â¦ the target cell is reached, it will trigger a specific response in that cell.
