This system results in stable blood concentrations of the hormones that are regulated by the pituitary gland (Reiser and Kemp, p.1).
This complex system of self-regulation means that there are multiple opportunities for the glands to stop working properly.
The hypothalamus, which is located in the brain, is, in many ways, the control center of the endocrine system. The hypothalamus secretes hormones that, in turn, either suppress or stimulate hormone release by the pituitary gland. The pituitary gland then uses the messages it receives from the hypothalamus to govern its secretion of stimulating hormones to other glands in the endocrine system. The pituitary gland sends messages to other glands in the endocrine system, as well as producing important hormones that regulate bodily functions without requiring the intervention of other glands. The hormones produced by the pituitary gland include: growth hormone, thyroid-stimulating hormone (TSH), adrenocorticotropin hormone (ACTH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin, vasopressin, and oxytocin. The parathyroid glands release parathyroid hormone, which regulates calcium levels in the bone and regulates bone metabolism. The adrenal glands have two parts: the adrenal cortex and the adrenal medulla. The adrenal cortex produces corticosteroids. The adrenal medulla produces catecholamines, such as adrenaline. The pineal body secretes melatonin. The reproductive glands secrete sex hormones and are responsible for the production of sperm or eggs. The pancreas secretes insulin and glucagon, which control blood sugar.
Of particular interest in terms of mental health, is the thyroid. In many ways the thyroid is a multi-purpose gland. It is responsible for regulating the metabolism. However, its role is not limited to the metabolism. The thyroid is instrumental in the brain and nervous system development in children, including children in utero, so that a mother with a malfunctioning thyroid gland may have an impact on a fetus. The thyroid is also responsible for helping regulate a number of other bodily systems. The thyroid is implicated in helping "maintain normal...
There are many different types of website that talk about biology; some of them include university websites which allows access to differing portals of biological information. Such websites as University of Michigan's "biology resource network" is an important source of information for all access to biology articles and databases from U. Of Michigan scholars and professors. Other websites include organization websites such as those of the American Society of
Biology of Behavior The biology of human behavior is rooted in the fact that human beings are animals, in the sense that they are biological creatures and are the result of millions of years of evolution with a physical make up that forms us into creatures that are fitter and more suitable for surviving and adapting to the physical environment all together. Even though a human being is still an animal
Mind's Content Wilhelm Maximilian Wundt and Franz Clemens Brentano were both German philosophers and psychologists working in the 19th to early 20th Centuries. Much of Wundt's work was discredited by the mid-20th Century, in part due to mistranslations of his work. Brentano, however, had a circle of followers who translated and rewrote his work to such an extent that he was published more after his death than during his life. The relationship
The blood with the IgG must be effectively removed from the body, or reduced to levels that will not allow the cells to be a danger to the infant. If caught early enough, plasma transfers for the mother can result in enough of a reduction of IgG levels to forestall the effects to the fetus. 8) Autoimmune diseases occur when, for a variety of reasons, the body responds to its own
Given a mosquito's vastly shorter life span, preventing the spread of the infection to more human hosts greatly reduces the number of viable parasites in existence (CDC 2009). 10) There are several reasons that viral infections are more difficult to treat and diagnose than bacterial infections. For one thing, viruses are not truly alive, and this makes it difficult to kill them. They are essentially packets of genetic information in tough
Mind and Behaviour Investigators in the discipline of psychology strive to determine factors that affect the mind and behaviour and how these interactions occur. In order to form hypotheses and answer questions, these scientists adhere to the scientific method. However, often psychological studies provide weak reliability and validity due to issues such as small sample sizes, inappropriate control groups or a complete lack there-of, as well as an inability to determine
