Adrenal Glands
Identification and description of organs which make up the endocrine system
The human body comprises of organ systems which distinct but work together as a coordinated single unit (Marieb & Hoehn 1-35). This paper will single out the endocrine system because discussing the organ system in entirety is beyond the scope of this assignment. The adrenaline glands form part and parcel of the endocrine system, thus, the relevance of the topic. The endocrine glands comprise glands which secrete hormones which help to modulate on the functions of the cells and/or organs. Hormones are chemical substances which regulate cell activities (Axelrod et al 452-459). They act like messengers in that they relay information from one part of the body to another. The main glands of the endocrine system are the hypothalamus, thyroid and parathyroid glands, pineal body, reproductive organs; pituitary and most important to this paper the adrenal glands (Axelrod et al 452-459).
To understand how adrenaline glands function requires that one explore the other organs of the endocrine systems aforementioned from above. Let us begin with the pituitary gland. The process is offset a signal sent from the hypothalamus to the pituitary gland in form of “releasing hormone”, which in turn necessitates the production of stimulating hormone into the circulation system (Melmed et al 34), on reaching the target gland or organ, it stimulates it to produce the required hormone. A rise in the level of the target hormone in circulation leads to a decline in production of the releasing and stimulating hormones to slow release of hormones from the target organ, leading to stabilization in the balance of the hormones circulating in the blood.
As for the thyroid glands, it is located on the lower part of the neck region. Production thyroid hormone takes place in this area (Iyengar & Venkatesh 39). Production of thyroid hormone is regulated by the actions of the pituitary glands. Parathyroid glands are located on either sides of the thyroid gland. They play a major role in regulation calcium and as well as the metabolism of bones. Pineal gland is a small, but important gland in respect to secretion of melatonin which is responsible for regulating sleeping patterns in the body. It is located in the in the middle part of the brain (Axelrod et al 452-459). As for the reproductive glands, they are the main producers of the sex hormones. Reproductive glands are different in males and females. In men, the testes are found in the scrotal bag, and they secrete androgens which are responsible for different male sexual characteristics. As for females, the ovaries are purposed for the secretion of estrogen and progesterone hormones, which are responsible for female characteristics such as growth and development of breasts and the menstrual cycle (Axelrod et al 452-459; Marieb & Hoehn 1-35 & Melmed et al 34).
The adrenal glands, which are very central to this study are triangular in...

Named after Thomas Addison, Addison’s disease is “caused by partial or complete failure of the adrenal cortex, which is the outer layer of the adrenal glands” (HealthCentral). This disorder occurs when the body fails to produce sufficient amounts of the hormones cortisol, aldosterone, and adrenal androgens. These are essential to the body because they produce hormones that
