Hypothalamus gland is present in the brain. Neurosecretory cells in the hypothalamus produce oxytocin and ADH and are transported down an axon to the posterior pituitary where it is stored.
For example, men with high levels of testosterone are prone to be more competitive and have The endocrine system essay higher level of aggression. People are advised to use iodised salt for cooking food so as to prevent goitre disease.
On the other hand, a person having too much growth hormone becomes very tall or a giant. So, it is necessary that the hormones are secreted by the glands in our body in precise quantities which are required for the normal functioning of the body.
Hormones regulate bodily functions and are specific in what responses they elicit. Malfunctions in the endocrine system also result in diabetes type 1 and 2. DNA function is of great influence over the cellular activities of the body and therefore such hormonal-DNA interaction can have effects as long as hours and in some cases days.
Each different type of secondary messenger evokes different responses by those cells they affect. The hypothalamus regulates the secretion of various hormones by controlling the main hormonal gland the pituitary gland.
Ovaries make two female sex hormones called oestrogen and progesterone. It is also in charge of cell The hypothalamus and pituitary gland are two parts of the brain that have important roles in integrating the nervous and endocrine system.
The hypothalamus is more or less the communication link between the nervous system and the endocrine system. Its hormones range from growth hormones that act on bones, to prolactin which stimulates mammary glands. All these actions of adrenaline hormone produce a lot of energy in our body very, very quickly.
Please note that pineal gland which is present in the brain has no known function. The endocrine glands are located in the head, neck and trunk of our body. Testes make male sex hormones called testosterone. After a hormone binds with a receptor molecule it via a transducer protein sends the hormones signal through the membrane.
The person having high sugar level in blood or diabetes is called a diabetic. Messages travel more slowly 5. Parathyroid glands secrete a hormone called parathormone.
The adrenal glands secrete adrenaline hormone. Long distance signaling takes place when an endocrine cell or neurosecretory cell releases hormones into the bloodstream. This can be explained as follows: We will now give the names of the endocrine glands, the hormones released by these glands, and the functions of these hormones in the human body.
The same can happen with males. They work in maintaining homeostasis and respond to changes inside and outside the body. An inositol phospholipid pathway can initiate breakdown of liver glycogen and DNA synthesis in fibroblasts.
During the female menstrual period, around ovulation time, estrogen rises to a peak. Hormones drive the endocrine system and without them the body could not function. The function of hypothalamus is to regulate the secretions of hormones from pituitary gland.
Made of neurons nerve cells 2. Iodised salt can provide all the iodine needed by thyroid gland to make sufficient thyroxine for our body. Thymus gland is large in young children but shrinks after puberty or sexual maturity. This is when regulators are released by a gland or cell into the interstitial fluids and are absorbed by nearby cells.
Before we end this discussion we would like to give a comparison of the nervous system and endocrine system or hormonal system for the control and coordination in humans and other higher animals. The function of insulin hormone is to lower the blood sugar level or blood glucose level.
In conclusion the glands of the endocrine system and the hormones they release influence almost every cell, organ, and function of our bodies. Hormone stimulation varies from growth and metabolic functions to ova and sperm production.Endocrine System – Essay Sample The endocrine system most basically includes a number of hormones and glands within the body.
As a system of glands, the endocrine system is defined by these glands, which secretes hormones into the body to regulate it, as an information signal system. The endocrine system is also called hormonal system. We will now discuss the endocrine system in humans in detail. In addition to nervous system, the endocrine system also helps in coordinating the activities of our body.
The endocrine system in our body consists of a number of glands (or tissues) which make, store, and release chemicals called hormones. There are a large number of endocrine glands. - The endocrine system is a group of glands distributed throughout the human body.
This group of glands secretes substances called hormones. These hormones discharge into the bloodstream (Shier, Butler & Lewis, ). The endocrine system does not have a single anatomic location. It is dispersed throughout the human body.
May 05, · The endocrine system is a group of glands distributed throughout the human body. This group of glands secretes substances called hormones. These hormones discharge into the bloodstream (Shier, Butler & Lewis, ).
The endocrine system does not have a single anatomic location. It is dispersed throughout the human body. The endocrine system is composed of organs and ductless glands that facilitate body development and homeostasis (Walker & Wood, ).The primary organs of the endocrine system include the pituitary gland, hypothalamus, pineal gland, thyroid gland, parathyroid glands, thymus gland, adrenal glands, sex glands, and the pancreas.
The Endocrine system is a body control system composed of a group of glands that maintain a stable internal environment, homeostasis, by producing chemical regulatory substances called hormones.
The endocrine system includes the pituitary gland, thyroid gland, parathyroid glands, adrenal gland, pancreas, ovaries, and testis.4/4(6).Download
