What is an instant messenger and why would you want one? Well an Instant Messenger is an innovative way to chat with friends, family, and even business associates all while you are online either at work or at home. Using them is as easy as signing online and opening the program. There are many different instant messengers on the market, one such messenger is Windows Live Messenger, which is an updated version of the Windows Messenger. Other such messengers are Yahoo, and AIM.
When deciding on which messenger you want to try, it is decision based upon need and ease of use. You want one that is easy to install, is compatible with your computer, and does what you need and want it to. Another thing to consider is how many problems or glitches the programs have, also how often is it updated.
When you go to set up your Instant Messenger, you might want to install any cameras and microphones in advance. Setting them up prior to installation will save you time getting them to work with your instant messenger. The messenger will simply detect them in your computer and adjust them for you. All of this happens the first time you use either of these features.
Now for those of us who cannot type very well or those who do not type at all, well then click the call or voice conferencing button on the messenger and be prepared to talk away. When you set up your webcam make sure, you have good lighting or a good camera, oh and brush your hair. Yeah I know we normally brush our hair anyways but remember they will be seeing a live picture of you.
For those of you in the corporate world, you can use instant messengers to help keep in touch with your employees, and online customers. Just imagine having all of your employees a click away no matter where they. It's possible whether they are online or if you have to give them a ring even text message them on their cell phones.
Also for those all important meetings where you need your hands free all you have to do is talk into your microphone. What if you need to show a presentation or something else? You can either upload an image and drop it into the messenger or set it in front of your webcam.
With all of these great features an Instant Messenger can fit all of your needs.
Hormones exist throughout nature. All multicellular organisms –both plant and animal- produce hormones. In fact, in all animals nearly early every tissue and organ system produces hormones, and in all cases those hormones act as chemical messengers that relay information and instructions from one individual or group of cells to another.
Hormones act as signal cells, and they pass that signal by traveling through the body. In most cases, hormones travel through the body in the body's blood stream. But other hormones –ectohormones- bypass the bloodstream and travel to neighboring cells in a process called diffusion. In both cases, the hormones send signals to other cells; signals that changes are about to happen.
Hormones initiate changes in cells when the hormones combine with specific receptors on the target cells. In most cases, the hormone receptor is embedded on the surfaced membrane of the targeted cells. When the hormone arrives at its destination cell, the hormone and receptor interact and initiate a series of effects within the cells' cytoplasm. Cytoplasm is the water-like substance that fills the cell.
The effect of hormones varies greatly and is dependent on the type of hormone that is in action. Hormones can stimulate or inhibit growth, induce the death of a cell, activate or inhibit the immune system, regulate metabolism, control reproductive organs, or prepare the body for new phases of life (like aging, or puberty). Hormones can even regulate the production and release of other hormones.
All of those activities are initiated by hormones, but the hormones themselves are controlled by other elements of the body. Hormone secretion can be stimulated by other hormones, nutrients, mental activities, and environmental changes. But despite the myriad functions of hormones, they can be classified into three basic categories. Amine-derived hormones are derivatives of amino acids (such as many thyroid hormones). Peptide hormones consist of chains of amino acids. The best known peptide hormones are insulin and growth hormones. Lastly there is lipid and phospholipids-derived hormones such as the steroid hormones, like cortisol, and testosterone.
Hormones play many roles in the body, but sometimes natural production is not sufficient and people must turn to pharmacology to obtain the levels needed for a healthy existence. Commonly prescribed hormones are estrogen and progestagens (often for contraception), insulin, thyroxine (for thyroid disorders), and steroids which are used to combat autoimmune diseases as well as respiratory disorders.
Hormones play an incredibly important role in the functioning of all living things. Whether naturally produced, or supplemented from another source, hormones are the instant messengers of life.
