Functions of the Endocrine System The Endocrine system along with the nervous system controls and regulates the complex activities of the body.
Endocrine diseases Diseases of the endocrine system are common,  including conditions such as diabetes mellitusthyroid disease, and obesity. Endocrine disease is characterized by misregulated hormone release a productive pituitary adenomainappropriate response to signaling hypothyroidismlack of a gland diabetes mellitus type 1diminished erythropoiesis in chronic renal failureor structural enlargement in a critical site such as the thyroid toxic multinodular goitre.
Hypofunction of endocrine glands can occur as a result of loss of reserve, hyposecretion, agenesisatrophy, or active destruction.
Hyperfunction can occur as a result of hypersecretion, loss of suppression, hyperplastic or neoplastic change, or hyperstimulation. Endocrinopathies are classified as primary, secondary, or tertiary. Primary endocrine disease inhibits the action of downstream glands.
Secondary endocrine disease is indicative of a problem with the pituitary gland. Tertiary endocrine disease is associated with dysfunction of the hypothalamus and its releasing hormones.
Endocrine, paracrine, and autocrine signaling have all been implicated in proliferation, one of the required steps of oncogenesis. Cushing's disease and Addison's disease are pathologies involving the dysfunction of the adrenal gland.
Dysfunction in the adrenal gland could be due to primary or secondary factors and can result in hypercortisolism or hypocortisolism. Cushing's disease is characterized by the hypersecretion of the adrenocorticotropic hormone ACTH due to a pituitary adenoma that ultimately causes endogenous hypercortisolism by stimulating the adrenal glands.
Adrenal insufficiency is significant because it is correlated with decreased ability to maintain blood pressure and blood sugar, a defect that can prove to be fatal.the ENDOCRINE SYSTEM They bind to specific target cells with receptors, regulate metabolism and the sleep cycle, and contribute to growth and development.
The endocrine glands and organs secrete these hormones all over the body.
2 The hypothalamus is a collection of specialized cells. The endocrine system is a chemical messenger system consisting of hormones, the group of glands of an organism that secrete those hormones directly into the circulatory system to regulate the function of distant target organs, and the feedback loops which modulate .
When the hormone reaches its target cell, it locks onto the cell's specific receptors and these hormone-receptor combinations transmit chemical instructions to the inner workings of the cell. When hormone levels reach a certain normal amount, the endocrine system helps the body to keep that level of hormone in the blood.
The endocrine system is a complex communication network made up of specialized cells, glands and hormones. The glands release hormones into the blood or the fluid surrounding cells in response to stimuli from inside and outside the body.
are secreted from the glands of the endocrine system, they are specific in that each hormone causes a response in a specific target organ or group of cells, rather than on the body as a whole.
Exocrine hormones are secreted via a duct into the blood and usually effect a distant organ or tissue. The endocrine system is a complex communication network made up of specialized cells, glands and hormones. The glands release hormones into the blood or the fluid surrounding cells in response to stimuli from inside and outside the body.
