They take messages from one part of the body the gland to tell another part of the body the target cell to do something important. The endocrine glands influence reproduction, metabolism, growth and many other functions.
Endocrine Glands & Their Hormones
The pituitary gland or hypophysis is an endocrine gland about the size of a pea and weighing 0. It is a protrusion off the bottom of the hypothalamus at the base of the brain , and rests in a small, bony cavity sella turcica covered by a dural fold diaphragma sellae. The pituitary is functionally connected to the hypothalamus by the median eminence via a small tube called the infundibular stem or pituitary stalk. Reduces smooth muscle contractions and blood flow within the intestine. Enhances effects of cholecystokinin , stops production of gastric juice.
The endocrine system is a network of glands and organs located throughout the body. However, while the nervous system uses nerve impulses and neurotransmitters for communication, the endocrine system uses chemical messengers called hormones. Keep reading to discover more about the endocrine system, what it does, and the hormones it produces. The endocrine system is responsible for regulating a range of bodily functions through the release of hormones. Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues what to do or how to function. The endocrine system is made up of a complex network of glands , which are organs that secrete substances.
Communication is a process in which a sender transmits signals to one or more receivers to control and coordinate actions. Together, these two systems are primarily responsible for maintaining homeostasis in the body. The nervous system uses two types of intercellular communication—electrical and chemical signaling—either by the direct action of an electrical potential, or in the latter case, through the action of chemical neurotransmitters such as serotonin or norepinephrine. Neurotransmitters act locally and rapidly. When an electrical signal in the form of an action potential arrives at the synaptic terminal, they diffuse across the synaptic cleft the gap between a sending neuron and a receiving neuron or muscle cell. Once the neurotransmitters interact bind with receptors on the receiving post-synaptic cell, the receptor stimulation is transduced into a response such as continued electrical signaling or modification of cellular response. In this way, neural communication enables body functions that involve quick, brief actions, such as movement, sensation, and cognition.

Endocrine glands are ductless glands of the endocrine system that secrete their products, hormones , directly into the blood. The major glands of the endocrine system include the pineal gland , pituitary gland , pancreas , ovaries , testes , thyroid gland , parathyroid gland , hypothalamus and adrenal glands. The hypothalamus and pituitary glands are neuroendocrine organs. The pituitary gland hangs from the base of the brain by the pituitary stalk , and is enclosed by bone. It consists of a hormone-producing glandular portion of the anterior pituitary and a neural portion of the posterior pituitary , which is an extension of the hypothalamus. The hypothalamus regulates the hormonal output of the anterior pituitary and creates two hormones that it exports to the posterior pituitary for storage and later release. Four of the six anterior pituitary hormones are tropic hormones that regulate the function of other endocrine organs.
Endocrine Glands & Their Hormones
The endocrine system is made up of the endocrine glands that secrete hormones. Although there are eight major endocrine glands scattered throughout the body, they are still considered to be one system because they have similar functions, similar mechanisms of influence, and many important interrelationships. Some glands also have non-endocrine regions that have functions other than hormone secretion.
На другой стороне авениды Изабеллы он сразу же увидел клинику с изображенным на крыше обычным красным крестом на белом поле. С того момента как полицейский доставил сюда канадца, прошло уже несколько часов. Перелом запястья, разбитая голова - скорее всего ему оказали помощь и давно выписали.
Только мы трое. Было ужасно жарко. - И вы уверены, что эта женщина - проститутка. - Абсолютно. Такая красивая женщина пошла бы с этим типом, только если бы ей хорошо заплатили.
Лампы, замигав, зажглись. Беккер поставил коробку на пол и подошел к столу.
Ну и что ты скажешь, моя красавица. Выйдешь за меня замуж. Лежа в кровати с балдахином, она смотрела на него и знала, что ей нужен именно. Навсегда. Ее завораживала глубина его темно-зеленых глаз, и она не могла отвести от них взгляд.
Я хочу уйти. Стратмор глубоко вздохнул. Ясно, что без объяснений ему не обойтись.
