Changes In The Endocrine System

The characteristics of the endocrine system that makes its reactions different from those of the nervous system is that: the endocrine system is slower at communicating than the nervous system, the endocrine system hormones only reacts to cells with distinctive receptors for that hormone, and the endocrine system hormones practically reaches all cells in the body.

The endocrine system includes of specific tissues and glands which secrete chemical messengers to the body called hormones. The glands are aided by the nervous system and chemical receptors in the blood and other hormones produced by other glands. Hormones regulate many functions of the body such as cellular metabolism, reproduction, sugar and mineral homeostasis and digestion.

*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 endocrine system is a group of glands including the pituitary, thyroid, parathyroid, thymus, testes, ovaries, adrenal, pancreas, and hypothalamus. The endocrine system interacts with the urinary, nervous, digestive, and reproductive system, each in different ways. The nervous and endocrine system interact through signals called

The Nervous System and the Endocrine are part of the human anatomy. Both of the system have their own jobs to keep the body to stay alive. The system are both unique in their own ways. In the system they have something are similar to each other. One thing that don’t have in common is there function and how they message to body to do a certain job to

Thyroid is small-sized organ in front of the human neck. It is a major gland in the

In short, the hypothalamus controls the flow of hormones in the body to maintain homeostatic levels.

Hormones are chemical substances that help to regulate processes within the body. The endocrine system is a system which secretes hormones straight into the circulatory system. Hormones either travel around the body in the blood stream, or in the fluid around cells.

Most of the hormones present in the human body are transported through the blood. Hormones according to www.pbs.org/wgbh/pages/frontline/shows/nature/etc/hormones can influence the function of the immune system and alter one’s behavior. These chemical signals are the reason for many factor including why one’s arms are the same length, why one can turn food into a viable fuel, and why one grows through puberty. Hormones are indicative of changes in target cells by binding to hormone receptors. In this way, even though hormones circulate throughout the body and meet different cell types, they only affect cells that possess the necessary receptors. Receptors of a specific hormone can be found on different cells or a small number of specialized cells. Per www.pbs.com/ the thyroid hormones act on different tissue types, stimulating metabolic activity throughout the body. Cells can have receptors for the identical hormone, but often also possess receptors for different types of hormones. The number of receptors that respond to a hormone determines the cell's sensitivity to a specific hormone. The number of receptors that respond to a hormone can change over time, resulting in increasing or decreasing the cell’s sensitivity. Often in up-regulation, the number of receptors increases to rising hormone levels, making the cell more sensitive to the hormone. Down regulation describes when a cell is decreasing the quantity of a cellular component. When the cells respond to a hormone, they express a specific receptor for that specific hormone. The hormone binds to the receptor protein, resulting in the activation of a mechanism that ultimately leads to cell type-specific responses. Receptor binding alters cellular activity, resulting in an increase or decrease in normal body processes. According to www.pbs.org/wgbh/pages/frontline depending on the location of the protein receptor on the

The structures of the body is created to interact with each other to keep all organisms healthy and functioning properly. Each system has its own way of connecting with each other to so each organism depends on the next one. The nervous system controls and has a direct connection inside the body which several organism. All the systems report directly to the brain and helps to adjust to respond the body and help the body function properly. There are two systems that are major that work together to keep the body flowing. There are two system that work together to keep many illnesses out of the body. The endocrine system that has chemical compounds and hormones this helps to the body pumping and give cells activities. Then the hormones flow into

The endocrine system bases its hormone secretion/production on sensory feedback as well as involuntary processes initiated by the brain. For example; hormones regulated by the pituitary

Hormones are compounds produced by the endocrine system that chemically regulate specific body functions. Steroid hormones have a biochemical unique 4-ring structure, including three 6-carbon rings and one 5-carbon ring. Androgens are steroids hormones synthesized primarily in the gonads and adrenal glands. Testosterone, the key androgen, affects sexual features and development. It maintains nitrogen balance and facilitates protein synthesis (anabolism). In men, it is made in large amounts by the Leydig cells of the testes and in women, by the ovaries. The pituitary gland in the brain secretes hormones called luteinizing hormones (LH) and follicle stimulating hormone (FSH) which regulate the number of Leydig cells in the testes. Also, LH controls how much testosterone the Leydig cells produce by regulating the expression of 17-b hydroxysteroid dehydrogenase. Since this enzyme mediates the rate-limiting step of testosterone synthesis, its inhibition can stop the synthesis of. Males synthesize 2.5 to 11mg of Testosterone a day while females produce about 0.25 mg daily.

The thyroid gland is a butterfly-shaped gland located at the base of the neck. The thyroid gland is an endocrine gland that secretes hormones responsible for some proteins synthesis, metabolic rate, metabolic development, and much more. Hypothyroidism and Hyperthyroidism are the main diseases processes that wee commonly see in a hospital setting.

The malfunctioning of the thyroid is among the widespread health problems in the world. Thus, there is a need for better and pervasive awareness about the thyroid, which is an endocrine gland found in the neck.

An understanding of both these concepts is pivotal to the understanding of the physiological needs and requirements of the mammalian body, the nervous system and endocrine systems are the body’s means of communicating this balance in conjunction with external systems in turn relaying messages back to the organs systems in their own specialized ways to target organs. Any deviation from this fundamental state of internal wellbeing are relayed to the hypothalamus which coordinates the responses needed to return the body back to a state of equilibrium via feed-back loops. Though these systems work differently they are not independent of one another and help maintain an organism’s balanced state.
