Chapter twenty-eight discusses neurotransmitters and hormones. The neurotransmitter is a messenger that travels between a neuron and a neighboring neuron to transmit a nerve impulse. A hormone is also a messenger that is secreted by cells of the endocrine system and transported through the bloodstream to target cells, this is where it is stimulated. There are many similarities and differences between a neurotransmitter and hormones. Neurotransmitters are found in the nervous system. They carry signals from nerves cells to other nerve cells. The signals travel through the nerve fibers, only taking a second. Nerve cells do not make direct contact with the cells they stimulate. However, it carries the message across a tiny gap that is separates the nerve cell from its target. Neurotransmitters are short-lived because they are released in short bursts and are broken down quickly or reabsorbed by the nerve cell. The nervous system depends on the neurotransmitters because they do all of the information-processing and vital switching. Neurotransmitters are released closed to their active site and are synthesized. Hormones are found in the endocrine system. Hormones travel through the bloodstream to their targets. The response can take up to second or hours to begin. The action they produce can last a long time. A single hormone can …show more content…
Synthroid contains amino functional group, it is one of two iodine-containing hormones from the thyroid gland. Synthroid is a nonpolar compound and activates the synthesis of enzymes when it crosses cell membranes and enter cells. Synthroid is needed if the thyroid does not produce enough of the hormone on its own. Synthroid interacts with thyrotropin-releasing hormone (TRH) and thyroid-stimulating hormone (TSH). TRH is a hormone released by hypothalamus, at the pituitary gland, it activates TSH. TSH releases amino acid hormones from the thyroid
