1. The general function of the endocrine system is gland based to produce hormones that help with metabolism, growth, tissues, and reproduction. The structure between the nervous system and endocrine system are very similar the basics of both systems involve triggering glands throughout the body from receptors. The function on the other hand is a little different because the nervous system makes a fast response through specific glands and muscles. While the endocrine system is more widespread it also works at a slower pace.
2. A tropic hormone are hormones that target other glands and are mostly secreted in the anterior pituitary. One example of a tropic hormone involves the Thyroid-stimulating hormone (TSH) stimulates the thyroid

The difference between humoral, hormonal, and neural stimuli in terms of releasing hormones is humoral stimulus happens when a hormone is released due to a change in the blood. For example, when your blood glucose rises that causes your body to trigger the release of insulin causing your glucose levels to go back down which cuts off the insulin. A hormonal stimulus happens in response to another hormone. An example of this is when the hypothalamus produces hormones in the pituitary gland. The pituitary gland then releases hormones that regulate the hormone production by other endocrine glands. Neural stimulus occurs when the nervous system stimulates endocrine glands to release hormones. The sympathetic nervous system stimulates the medulla to release certain hormones like epinephrine and …show more content…
Organ systems like the integumentary, skeletal, nervous, and endocrine all play a big role in helping the body maintain homeostasis. The integumentary system helps maintain by giving protection, regulating body temperature, and sensory receptors. All of this plays a big role maintaining the internal conditions so the body may function. The skeletal system helps by producing red blood cells in place of the old ones that die. It also helps to maintain the calcium levels in our blood stream. The nervous system maintains homeostasis by controlling and regulating other parts of the body like letting you know when you’re tired or when you’re hungry. It makes sure the body is acting how it should by using receptors. The endocrine system releases hormones that are sent to different parts of the body that control the body’s reaction to things like stress, pain, and growth. These hormones give directions to the body for the fight or flight response so that it can adjust and maintain
The physiological activity of different hormones depends on its concentration within the circulatory system. The effects of too high or too low a concentration can be damaging and this level must be controlled. The endocrine system relies on negative and positive feedback systems to regulate hormone production and secretion.
Homeostasis involves the whole body, but certain organs have larger roles in maintaining the balance. The liver and pancreas maintain suitable glucose levels in the blood, with kidneys removing metabolic waste products and maintaining suitable salt and water levels within the blood. The skin and liver help maintain body temperature with lungs controlling oxygen and carbon dioxide levels in the blood and the blood itself transporting the nutrients and waste products around the body.
The prevalence of diagnosed endocrinological disorders has increased during the 20th century and into the 21st century. These disorders interfere in the day to day lives of those who have them. A common disorder of the endocrine system is diabetes, type 1 and type 2. While there have been many treatment methods used of the years the use of biotechnology like recombinant DNA technology has revolutionized and standardized the treatments.
Sensory neurons behave to physical stimuli such as light, sound and touch and send observation to the central nervous system about the body’s surrounding environment. Motor neurons, based in the central nervous system or in peripheral ganglia, disseminate signals to mobilize the muscles or glands.
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,
"Neurones monitor or control specific cells or groups of cells" (Martini et al. 2014). The nervous response is rapid, however precise and short-lived, due to the fact that neurotransmitters are broken down and recycled very quickly after they have diffused across the synaptic cleft - in contrast, not all life processes are short-lived, and many require a longer response time. For example; the body continually maintains reproductive capabilities for many years, and other life processes such as growth and development require responses with a long-life span. In addition, not all of the cells in the body are innervated, which means that some cells in the body cannot be reached by the nervous system. As such it is evident that hormones have a major role to play in cellular communication, and the nervous system on its own would not suffice. (Martini et al.
There are three patterns that regulate hormone secretion; Non-hormonal, neuronal, and Hormonal. In Non-hormonal, the release of a hormone is dependent on the amount of another substance that is not a hormone. For instance, if the concentration of glucose in the blood stream is to low the pancreases with release glucagon which causes the liver to convert glycogen to glucose. Neuronal is the regulation of hormones based on the emotions and stress a person feels. A common example of this is adrenalin (epinephrine) which is the fight or flight hormone. Finally, there is Hormonal with is regulated by other hormones. An example of this would be any releasing hormone produced by the Hypothalamus that causes the release of Tropic hormones from the anterior pituitary gland.
All organ system work together; in order to keep and support the conditions that the cells, tissues, and organs need to function properly. Each organ system has an important function in the body. There is one system that is not as well known as other; it is the integumentary system. Most people know the organs of the integumentary system, but they do not know that these organs work together to form this system.
The hypothalamus is a part of the brain that has direct control over the release of hormones from the pituitary gland. These hormones are called regulatory hormones. They are considered regulatory hormones because they are molecules secreted into the blood to regulate secretion of anterior pituitary hormones (McKinley 669). Regulatory hormones are produced in the hypothalamus and they travel to the anterior lobe of the pituitary gland; therefore affecting target organs to produce certain functions in the body, and Graves disease is related to this process.
The integumentary system is an organ system that is often overlooked when compared to other major organ systems. The importance of the integumentary system and its role in thermoregulation and its first line protection for the body is of utmost importance. The integumentary system includes the following organs: skin, hair, nails, and exocrine glands. Skin is a very large organ, and is the most important organ of the integumentary system. The surface area of skin is about 20 square feet, and weighs about 10 pounds. The importance of skin is to protect the body from UV light, chemical, disease and physical trauma that can occur to the body. The skin helps regulate body temperature. It does this through storage of adipose tissue and through secretions of sweat. It also allows for sensing touch, Different temperatures that the body comes into contact with are sensed and these messages are sent to the brain so that a reaction can occur in order to protect the body. A very important part of the integumentary system is that it is responsible for making vitamin D. Vitamin D is key in the function of calcium absorption.
The endocrine system consists of six parts; pancreas hypothalamus, thyroid, pituitary gland, ovary, and adrenal gland. The pancreas is a large gland that produces hormones that regulate blood sugar; produces enzymes that break down carbohydrates, lipids, proteins, and nucleic acids; and produces sodium bicarbonate, a base that neutralizes stomach acid. The hypothalamus is a brain structure that acts as a control center for recognition and analysis of hunger, thirst, fatigue, anger, and body temperature. The thyroid is a large gland in the neck that secretes (produces) hormones regulating growth through the rate of metabolism. The pituitary gland is in the base of the skull that secretes nine hormones that directly regulate many body functions and control the actions of several other endocrine glands. The ovary ( found in females) is a gonad that produces eggs. The adrenal glands are a pair of glands located above the kidneys, which produces epinephrine and norepinephrine. The endocrine system main function is to release hormones that affect activities of other cells.
The human body, known for being the most complicated work of cells, tissues, systems and organs is a fascinating masterpiece; inside the human body, we have twelve major organ systems. One of those systems is the Endocrine system; it is responsible for the coordinating many of the bodies’ functions. The endocrine system is made of many organs, one of them is the thyroid gland, it is responsible for manufacturing hormones with help regulate metabolism. Metabolism more commonly known as the chemical process in which an animal or human uses water and food to heal, grow and make energy. When the thyroid produces too much hormones, it can cause an issue leading to Hyperthyroidism and when insufficient hormones are produced it leads to Hypothyroidism. Thyroid problems can lead to Hashimoto’s Disease, Thyroid Nodules, and Graves’ Disease.
Gastrin hormone is a hormone that is secreted by Gastrin cells ( G cells) by the pyloric gland which is located in the antral portion of the stomach. It is a large peptide which is secreted in two forms: G-34 which consist of 34 amino acids and its the large form of gastin, and the G-17 that consist of 17 amino acids and it is the small form of gastrin which is more abundant. It is secreted due to the presence of food in the stomach ( chemical stimulus) and by the aceTylcholine released by nerve fibers.
The endocrine system plays a crucial part in homeostasis by releasing hormones that regulate the cellular activities. Hormone can be defined as a chemical messenger, which travels through the blood to act on target cells/organs and is produced by cells or tissues.
The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
