INTRODUCTION According to Innerbody.com, the endocrine system is composed for the glands and the

Explain the characteristics of the endocrine system that make its reactions different from those of the nervous system.

The nervous system uses sensory receptors, nerves and your brain to control your cells, and acts quickly. The endocrine system uses your circulatory system and hormones to care for your cells and acts more slowly. The reproductive system and endocrine systems use hormones to function. The nervous and endocrine systems are connected by sending information to the hypothalamus and uses the autonomic nervous system to transmit what activity needs to take place in the body. This activity might be what hormones are needed, or what sensations the body feels. While the nervous and endocrine systems send information to the hypothalamus, the reproductive system receives information from the hypothalamus. So all three systems do work together, although

*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

The pituitary is stimulated to release growth hormone (GH) by growth hromone releasing hormone (GHRH) produced in the hypothalamus. It is inhibited from releasing growth hormone by growth hormone release-inhibiting hormone(GHRIH), also produced by the hypothalamus.

According to Shier, Butler & Lewis (2009) “other glands that produce hormones and thus are parts of the endocrine system include the pineal gland and the thymus gland”. Shier et al., 2009 argued the pineal gland, located deep between the cerebral hemispheres, secretes hormone melatonin that acts on certain brain regions that function as a biological clock. The changing levels of melatonin across 24 hours enable the body to know when day is and when is night.

The Endocrine System plays a very prominent role in the body and a healthy life for an individual. This system is a foundation of hormones and glands. There are multiple glands throughout the body controlled by the pituitary gland. The pituitary gland is about the size of a pea that weights about 0.5 grams. (1) This gland is located at the base of the brain and rests on the hyperphysical fossa of the sphenoid bone in the center of the middle cranial fossa. (1) The Endocrine system also contains the thyroid gland, which is located in the neck and it controls the growth and the amount of energy of the body.

The Adrenal glands secretes compounds including cortisone and adrenaline which helps you react to emergencies. This gland regulates your metabolic process in the cells and blood pressure. The Pineal gland produces melatonin, which helps regulate reproductive hormones. The Reproductive glands which includes the ovaries and testes, these glands influence blood circulation and determines mental vigor and sex drives. These glands all play major roles which work hand in hand with other body systems constantly.

The endocrine system is a very important part of the anatomy and physiology of the human body. Knowing and understanding how this system operates and what contributes to its failures can be helpful in understanding how the body contributes to overall health and wellness. The purpose of this essay is to highlight and describe the adreanal glands, an important component of the endocrine system. In this analysis, this essay will describe the location and normal physiology of the adrenal glands and discuss the hormones that are associated with this part of the body. Also the feedback mechanisms and communication system within the group of endocrine glands will be discussed. Finally a malfunction of the adrenal glands will also be introduced to highlight how disease and illness can negatively impact the endocrine system and the human body's means of healing.

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 hypothalamus is the bridge between the nervous system and the endocrine system. In terms of the nervous system, the hypothalamus is involved as it receives information from different parts of the nervous system. The hypothalamus is responsible for maintaining homeostasis, including the controlling regulation for body temperature, thirst, and blood pressure. For example the hypothalamus acts as a thermometer for the body (temperature of blood passing hypothalamus acts as thermometer), and in response it stimulates sweating or vasodilation to cool down. Whereas an endocrine organ, the hypothalamus is involved with the pituitary gland. Hormones such as Gonadotropin-releasing hormone, anti-diuretic hormone or corticotrophin hormone are all secreted by the hypothalamus. The release of hormones means it may lead to inhibiting or releasing hormone from the pituitary gland. The hypothalamus is able to work things between the anterior and posterior pituitary due to

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 nervous system and the endocrine system connect- the endocrine system hormones provide feedback to the brain to affect neural processing enabling the nervous system to work. The endocrine system also enables the hypothalamus which is a portion of the brain that contains a number of small nuclei with a variety of functions to control the pituitary gland and other endocrine glands in order to interact with the nervous system; therefore it is vital the interrelationship between the nervous and endocrine systems in order for the nervous system to carry messages to and from the brain and spinal cord to various parts of the body and for the endocrine system to function well by the made up of glands to produce and secrete hormones, chemical

The endocrine system works to control and regulate the body. It works by hormones being released into the blood and carried to target cells and tissues. The control center of the endocrine system is the hypothalamus. The hypothalamus has direct control over the pituitary gland
