The Endocrine System Essay

*Endocrine glands produce – hormones, they work with other hormones to perform many functions including: control water & electrolyte balance, regulating carbohydrate metabolism, working as neurotransmitters, maintaining stress & inflammation, regulate reproductive functions

Adrenal glands, which are also called suprarenal glands, are small, triangular glands located on top of both kidneys. Adrenal glands are made of two parts: the outer region, called the adrenal cortex, and the inner region, called the adrenal medulla. The adrenal glands work with the hypothalamus and pituitary gland, as well and secrete hormones that affect metabolism, blood chemicals, and certain body characteristics. Adrenal glands also secrete hormones that help a person deal and manage with both physical and emotional stress.

There are many causes of hyperthyroidism, but the symptoms of hyperthyroidism are the same no matter what causes the over expression of thyroid hormones. The main symptoms of hyperthyroidism are fatigue, shortness of breath, weak muscles, anxiety, difficulty sleeping and heart palpitations. Interestingly, even with an increase in appetite the patient will have weight loss.

The pituitary gland is part of the Endocrine system and secretes hormones for growth, metabolism, reproduction, etc. It works with the hypothalamus in cognitive functions and is widely important for memory, emotional behavior and a multitude of tasks to maintain homeostasis in our bodies.

The key glands involved in the endocrine system are the pituitary gland, pineal gland, hypothalamus, pancreas, ovaries (females), testes (males), thyroid gland, parathyroid glands and the adrenal gland.

The endocrine and nervous system are two control systems of the human body that are interconnected with each other. The nervous system can be described as fast-acting with short-term effects, while the endocrine system is slower-acting with longer lasting effects. The hypothalamic-pituitary axis is one example of a connection between the two systems where neurons can signal the release of hormones from specific endocrine glands.

The function of the endocrine system is the production and regulation of hormones. Hormones regulate different body functions including growth, development, mood, tissue function, metabolism, and sexual function.

The pituitary gland is apart the endocrine system. The pituitary is also a master gland in the brain. The endocrine system sends hormones throughout the body in the blood stream. The hormones in our body play an important role. They influences our interests in many things, such as the food that we like to eat. They also affect many other tissues in the

Pineal gland - is located behind the third ventricle. It helps regulate the body’s internal clock and circadian rhythms by secreting melatonin. It has some role in sexual development.

The hypothalamus gland is the control center of the endocrine system and directs the pituitary gland to secrete certain hormones. Hormones have a variety of effects on the body. The pituitary gland stimulates the thyroid gland to produce certain hormones. The thyroid gland plays a vital role producing those hormones that have a direct impact on the Endocrine System. The thyroid gland produces two hormones; triiodothyronine (T3) and thyroxine (T4).

The pituitary regulates and controls the secretion of hormones from other endocrine glands, which in turn regulate many body

These glands are accountable for the production and regulation of hormones that are released into the blood circulation and dispersed to target sites. Hormones behave as chemical carriers regulating essential body functions such as blood pressure, sexual reproduction, blood glucose levels, fluid stability and development (GreenFacts Scientific Board). However recent studies suggest that a variety of substances such as natural and man-made are interacting with the endocrine system resulting in adverse health effects, such as a decrease of male fertility, deformities in male reproductive organs, female reproductive disorders, and potiental effects of the development of the nervous system and immune system. With a decline in quantities of males reproducing throughout living organisms

Hypothalamus, pituitary gland, pineal gland, thyroid gland, parathyroid gland, adrenal gland, pancreas, gonads and thymus are the glands that secrete hormones; however, there are also some non-glandular organs and tissues that secrete hormones such as

2003, pg. 23). The vertebrate hormones are secreted in response to three types of stimulus. The first stimulus can be the presence or change in concentration of a specific substance in the blood; for example an decrease in blood glucose levels triggers the secretion of glucagon hormone from the ?-cells of the islets of Langerhans in the pancreas. Another stimulus which initiates the release of a hormone, is the presence or change in concentration of another hormone in the blood such as the presence of thyroid stimulating hormone which clearly stimulates the thyroid gland to secrete the amine hormone, thyroxin. The third and final type of stimuli to cause a change in hormone action is by nervous stimulation which involves neurons of the autonomic nervous system and can be clearly illustrated in the secretion of adrenaline from the adrenal gland in

The endocrine system is the accumulation of organs that create hormones that direct digestion system, development and advancement, tissue capacity, sexual capacity, generation, rest, and state of mind, in addition to other things. Homeostasis is maintained by regulation of body temperature, pulse, pH, glucose centration, etc.
