The suprarenal gland (adrenal gland) is located at the top of each kidney; therefore each person has two adrenal glands. Adrenal glands appear to look like triangular shaped objects on top of the kidneys. The adrenal glands are dire in creating different hormones that are necessary for a fully functional body. With each adrenal gland, they are both made up of two different sections. The first section being the adrenal cortex, and that is located on the outer region of the adrenal gland; the second section called the adrenal medulla, and that is located in the inner region of the adrenal gland. Both sections of the adrenal glands, the adrenal cortex and the adrenal medulla, perform distinct separate functions.
The adrenal cortex, the outer region of the adrenal gland secreted different hormones that are responsible for the body’s metabolism, the chemicals in the blood, and on different body characteristics. One subject of hormones consists of corticosteroids, and a part of that is hydrocortisone, also referred to as cortisol. Cortisol is the hormone that helps control the body’s use of fats, proteins, and carbohydrates. The pituitary gland is a pea shape sized gland that is located in the center of the skull. The pituitary gland is an extremely important link between the nervous and endocrine system. The pituitary gland regulates the amount of cortisol released by the adrenal glands. The role of cortisol in the body is extensive, cortisol helps the body manage stress, reduce inflammation, immune system function, and allows homeostasis to occur inside of the body, providing balance in a plethora of different ways. A hormone called aldosterone regulates the level of sodium, and potassium in the body to maintain blood volume along wi...

...s be changing. Describing the adrenal glands in the endocrine system is no easy feat, there are so many different aspects to think of, and take into consideration. The adrenal glands controls almost all of hormone stimulation, and regulation, and it is on coordination with everything in the body, and that is how the endocrine system provides homeostasis for the body.

The location of the pituitary gland is in the sella turcica of the sphenoid bone and attaches to the hypothalamus(Marieb & Hoehn 441). The Hypothalamus is included in the function of the pituitary gland as it sends chemical stimulus to it(Marieb & Hoehn 442).Part of the pituitary is called the “ master endocrine gland” due to the fact that is produces many hormones that affect the whole body(Shannon 175).This part of the pituitary gland is called the anterior pituitary(Marieb & Hoehn 601). There are six hormones that the anterior pituitary secretes normally. These Hormones are growth hormones,thyroid stimulating hormones,adrenocorticotropic hormones,luteinizing hormones,follicle stimulating hormones and prolactin hormones( Shannon 175).The Hormone prolactin is one that in normal function stimulates the act of lactation for new mothers to feed their baby(Shannon 175).
The thyroid gland is located in the anterior, middle portion of the neck. Many of the bodies’ hormones come from the thyroid. According to Porth 2011, “the thyroid hormone increases the metabolism and protein synthesis in nearly all of the tissues of the body.” (p. 784). When these hormones are not regulated, a thyroid disorder develops such as hypothyroidism and hyperthyroidism.
Tumors or Lesions to the Hypothalamus Patient The Hypothalamus is a small area near the base of the brain just ventral to the thalamus. It has widespread connections with the rest of the forebrain and the midbrain. Partly through nerves and partly through hypothalamic hormones, the hypothalamus conveys messages to the pituitary gland, altering its release of hormones (Kalat, 2003). Any type of damage to a hypothalamic nucleus, such as tumors or lesions, may lead to abnormalities in one or more motivated behaviors, such as feeding, drinking, temperature regulation, sexual behavior, fighting, or activity level.
Adrenocorticotropic hormone (ACTH): a hormone produced in pituitary gland that targets the adrenal cortex to release corticol
Cortisol is in the class of hormones called glucocorticoids and affects almost every organ in the body. One of the most important functions of cortisol is to help regulate the body’s response to stress. Cortisol is also responsible for other necessary functions including: helping to maintain blood pressure and cardiovascular functions, helping to slow the immune system’s inflammatory response, helping to balance the effects of insulin in breaking down sugars for energy, helping to regulate the metabolism of proteins, carbohydrates, and fats, and helping to maintain proper arousal of sense of well being. The amount of cortisol is precisely balanced and regulated by the brain’s hypothalamus.
The hormones produced from the endocrine system come from a wide range of different places. Among those responsible for hormone production are the glands and a few organs as well. The glands that are involved are the pituitary, thyroid, thymus, parathyroid, and adrenal. The organs, which also play a vital part, are the pancreas, gonads, kidneys, heart, and parts of the digestive tract. All these different glands or organs work together in the production of certain hormones. Those produced in one location will almost always have an effect on many other areas of the body, not just the surrounding tissues.
The thyroid organ, though small, impacts every cell in the body by providing metabolism regulation (endocrine web). This butterfly-shaped, endocrine organ located at the neck, secretes hormones to control the body’s metabolism - or the way the body uses energy that help the body with energy, manage heat, and help organs such as the heart and brain function properly (thyroid.org). When not functioning properly, thyroid dysfunctions occur disrupting the three points of control: the hypothalamus in the brain, the pituitary gland, and the thyroid gland. Common thyroid disorders include Hashimoto’s, Graves’ disease, thyroid disorders like hypothyroidism and hyperthyroidism, and nodules or goiters (health line).
The thyroid gland plays a major role in the endocrine, thyroxine, triiodothyronine and metabolism system. The gland can be found in the front of the neck and above where the collar bones meet. The thyroid gland controls the body by releasing T4 and T3 hormones. Controlling metabolism plays an important role when regulating mood, weight,

The Spleen by Anne Finch, the Countess of Winchelsea, presents an interesting poetic illustration of depression in the spleen. The spleen for Finch is an enigma, it is mysterious, shape-shifting, and melancholic. Melancholy leads the subject to flashes of a grander, terrifying emotion: the sublime. The subject of Finch’s Pindaric ode experiences the sublime, and yet has the uncanny ability to reflect and reason on the feeling with acuity--even though the subject suffers from depression, which in effect dulls sensory information. The fact that she intensely perceives the sublime suggests a paradox where dulled senses can produce a penetrative emotional episode. To understand the paradox, the theory of the sublime and Finch’s engagement with the sublime in The Spleen must be traced to conceive the state of the dulled mind in the thrall of an infinite, and transcendent wave of emotion. The focus of this essay is that Finch understands that Dullness, as a by-product of depression, enables rational thought during a sublime experience. Furthermore, she thus illustrates her experience through images where she emphasizes her sensory information and her feelings, which were supposedly numbed by depression. Her feelings, indicated in The Spleen, are the crux to how Finch is able to simultaneously feel numb, and process the sublime.
The thyroid gland is part of the endocrine system, and it is controlled by the pituitary which is known as the “master gland” of the endocrine system. The pituitary controls the thyroid by producing Thyroid Stimulating Hormone (TSH) which stimulates the production of thyroid hormones. . The thyroid gland secretes two main hormones: Thyroxine (T4) and Tri-Iodothyronine (T3). These hormones increase metabolic rate, heat production, oxygen consumption, appetite, growth hormone secretion, alertness and quicker reflexes. The thyroid gland is located in the anterior portion of the neck, beneath the Adam’s apple. It is divided in two lobes on either side of the windpipe: right lobe and left lobe. These lobes create what looks like a butterfly shape. The gland is essential to the contribution of maintaining the homeostasis of the body. It plays a role in monitoring the body’s expenditure of energy and running the body’s metabolism.

The male reproductive system is a set of organs that works together to produce sperm which will later in life fertilize females eggs. The testes are the most important part of the system because it produces sperm cells. It is similar and looks similar to ovaries of a female’s reproductive system because it also holds what they need to reproduce. Its job is to produce the sperm cells needed to reproduce. Due to hormonal imbalances the production of sperm cells may not even be possible in some males. Testosterone is the male the hormone that gives men there manly characteristics. It is made up of hydrogen, carbon, and oxygen with a white color. In the male body it helps develop sex organs, a deeper voice, and facial hair (Khalid, 2013). Cancer or a genetic disorder in males is the most common thing that cause the reductions of testosterone production in the body. Behind the testes is the epididymis which lets sperm go through the vas deferens from the testes (Dictionary, 2014). It looks like leach the way it is position right on the testes but it is thinner.

...culatory system. Pituitary gland is a growth hormone that helps in mertabolism and develops reproductive organs. The thyroid controls metabolsim on the rate that the body breaks down food. Adrenal gland secretes many hormones including adrenaline which prepares the body to react in a stressful situation. The pancreas produces digestive enzymes and insulin. Ovaries produce ova and estrogen. Testes produce sperm cells and testosterone. To stay healthy you should get a regular medical check-up, eat a well-balanced diet, sleep at least 8 hours, and decrease stress in your life. Some problems are growth disorders, diabetes, and obesity. Puberty begins at different times for girls then boys. Girls start around ages 9-13 and boys are ages 10-15.
Each tear gland is about the size and shape of an almond. These glands are located behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye.Heavy laughter or crying causes muscles in the upper eyelid to squeeze the lachrymal gland. This produces tears that flow too fast to be drained away. The eyelashes catch many flying particles that otherwise would enter the eye.
