The Endocrine System Essay - 601 Words

The Endocrine System The function of the endocrine system is to regulate the body functions by the use of hormones. The structure of the endocrine system is therefore the structure and location of all the main endocrine glands. The pituitary gland, thyroid, pancreas, adrenal glands, and the sex glands (testes) are some of the more important ones, but there are several others. The glands secrete hormones directly in to the blood, which act as messengers. The nature of messenger which is released by the gland, once it has recognised the stimulus is chemical. The messenger is transported in the blood stream, and its speed is relatively slow. The messenger then travels to its target cells, and its†¦show more content†¦The electrical messenger is transmitted through the nerve cells; this process is a lot faster than the endocrine system, which enables the response to be that much faster as well. Another noticeable difference in the two systems is in the type of receptors, in the endocrine system t he type of receptors is cells, while in the nervous system there are various types of receptors including heat, pressure. As in the endocrine system, the effects of the messenger generally takes a long time, in the nervous system the effect is immediate. And the response is also very localised sometimes directed at just one muscle. As I mentioned earlier, in the endocrine system, the function of the endocrine system is to regulate the body functions by the use of hormones. There are two types of hormones. Steroid hormones and Amino-acid based hormones. Steroid hormones are produced by the Adrenal Cortex, the Ovaries, and the Testes. Steroid hormones don’t have to bind with the plasma membrane receptors of the target cells; they enter freely. Within the cytoplasm, a steroid hormone can bind with a receptor protein; it will then enter the cell nucleus and bind with the DNA, where it will trigger changes in the chromosomes. The Hormone –Receptor unit attaches to the DNA, this attachment activates certain genes in that cell, causing particular proteins to be produced.

The Endocrine System consists of many components but is made up of Endocrine glands which have no ducts and usually secrete their hormo nes directly into the tissue fluid. It also contains many tissues that secrete hormones. The glands of the Endocrine system are located throughout the body but are mostly central to the body. The system has manyRead MoreEndocrine Systems : Hormones And The Endocrine System1390 Words   |  6 PagesEndocrine System:†¨ Hormones are chemical substances that act as messengers in the body.

One of the major systems we need is the endocrine system. The endocrine system is the collection of glands of an organism which secrete hormones directly into the circulatory system, which then distributes the hormones to specific organs.
