Endocrine System

The endocrine system has to do with the hormones of the body. Hormones are chemical messengers that travel throughout the bloodstream to other tissues. These hormones are secreted by endocrine glands throughout the body. Hormones help with the functions of certain organs and glands and help with digestion, muscle contraction, sex hormones for reproduction, sleep, and much more. They can really dictate how chemicals in the body react. The major function of the endocrine system is to maintain the body’s homeostasis. There are three different types of hormones and they are amino acid derivatives, peptide hormones, and lipid derivatives. Amino acid derivatives are related to amino acids and are associated with the hormone known as melatonin that is secreted by the pineal gland. Peptide

These glands and organs are controlled by stimulation from the nervous system, chemical receptors in the blood, and hormones produced by other glands. Hormones can only affect cells that have the correct receptors and the levels of hormones can be regulated by the nervous system and many other factors. If a cell is exposed to high levels of hormones they can begin to reduce the number of receptors produced and this can begin to cause problems.
Without the endocrine system the body would not be able to function properly. Pathologies involved with this system can become very serious. Although the glands in this system are very important we are able to live without some with the help of medicine to produce the hormones. For example if someone has thyroid cancer they are able to have their thyroid removed but would have to take the hormonal medicine for the rest of their

    Those hormone receptors recognize the specific shapes, and respond only to those hormones that are recognized, they can be located on cells in the different body tissues. The responses which are triggered by hormones depends not only on those hormones, but also on the target cell. When the target cell receives the hormone signal, it can respond to them in the different ways like: stimulation of protein synthesis or secretion of the products and activation or deactivation of enzymes. The target cell activation depends equally on three factors, the blood level of the hormone, the relative number of the receptors for that hormone on the target cell or in the target cell and the other factor is the strength of the binding between the hormone and the receptor. There are two pathways of hormone action, one which involves the intracellular hormones receptors and one which involves cell membrane hormones receptors (appendix 4).…

    The endocrine system is made up of glands, which are located throughout the body and secrete hormones into the blood (Herlihy, 2014). Hormones in the body are secreted to control particular organs and tissues, being secreted by feedback control loops, the central nervous system or biorhythms (Herlihy, 2014). For example they regulate metabolic processes, assist in growth and reproduction, during times of need such as trauma or illness and with regulation of water and electrolytes in the body (Herlihy, 2014). Hormones are either classified as proteins, which are the most common or steroids, which are only secreted by the adrenal cortex and sex glands (Herlihy, 2014). They attach to tissues or organs, which are known as targets (Herlihy, 2014).…

    Although tumors may cause hypersecretion of thyroid hormones, but sometimes, they could cause the glands to reduce the amount of secretion of the hormones. This is due to the competition of blood supply to feed the tumors causing lack of blood supply to the glands, resulting under secretion of the hormones. Tumors could also cause…

    The hypothalamus in located in the brain. It is responsible for regulating body temperature, some metabolic processes and it is the main part that controls the autonomic nervous system. The hypothalamus is also in control of the production of many vital hormones that play a major role in maintaining the right standards for your body and chemical substances that help control different cells and organs. The hormones released from the hypothalamus control physiologic purposes, such as sleep, mood or sex drive. The pituitary gland is an endocrine gland that controls the other endocrine glands and has a major impact growth, metabolism and maturation.…

    First, Nellie, you must understand that our bodies make lots of different hormones. A hormone is usually a special protein that certain cells in the body make. Once the hormone is made, it enters the blood so it can travel to where ever it is needed in the body to make a specific thing happen. The body continues to make more of the hormone as needed in order to make happen what it is the hormone does. Certain cells make one type of hormone, while other cells make a different type of hormone and so on.…

    Yet, this bodily process is a key contributor to normal everyday functions, particularly metabolism and digestion. Gastric acid secretion is precisely regulated by neural (acetylcholine), hormonal (gastrin), and paracrine (histamine; somatostatin) mechanisms. The prime inhibitor of acid secretion is somatostatin. Its inhibitory paracrine effect is mediated predominantly by receptors coupled via guanine nucleotide binding proteins to inhibition of adenylate cyclase activity. All the pathways converge on and modulate the activity of the luminal enzyme, H+, K+-ATPase, the proton pump of the parietal cell.…

    This information allows for cells to distinguish each other apart, as well as form a connection with synapses. However, with too much Glutamate it can be toxic to the brain causing over excitation of the cell and causing them to die. Glutamate exerts its’s effect on the brain by biding to specific receptors on the nerving. Patient’s with Huntington’s Diseases are over activated by glutamate which is due to the impairments in the patient’s energy metabolism. According to the National Library of Medicine “Patients carrying the mutation display motor dysfunction, manifested as chorea in early stages, then as akinesia and sometimes dystonia in later stages.…

    The important function of ciliary epithelium is to produce aqueous humor. Aqueous humor is required to build up the intraocular pressure (IOP), that maintains the eye shape, and also nourishes avascular eye tissues, like lens and cornea. Ciliary muscle helps for proper accommodation of lens (Janssen et al. 2012). Previous studies reports , CB synthesizes and expresses multiple neuro endocrine proteins such as different as neurotensin, natriuretic peptides,and somatostatin, steroid-converting enzymes, transferrin, transthyretin,angiotensin, and growth factors(Coca-Prados and Escribano 2007) these endocrine molecules play role in regulating IOP, the composition of the aqueous humor.…
