The endocrine system is an integrated system of small organs that involve the release of extracellular signaling molecules known as hormones. The testicle (from Latin testiculus, diminutive of testis, meaning "witness" virility plural testes) is the male Hormones (from Greek ὁρμή - "impetus" are chemicals released by cells that affect cells in other parts of the body The endocrine system is instrumental in regulating metabolism, growth, development and puberty, tissue function, and also plays a part in determining mood. Metabolism is the set of Chemical reactions that occur in living Organisms in order to maintain Life. Human development is the process of Growing to maturity In biological terms this entails growth from a one-celled Zygote to an adult Human being Tissue is a cellular organizational level intermediate between cells and a complete organism [1] The field of medicine that deals with disorders of endocrine glands is endocrinology, a branch of the wider field of internal medicine. Medicine is the art and science of healing It encompasses a range of Health care practices evolved to maintain and restore Human Health by the Endocrinology (from Greek grc ἔνδον endon, "within" grc κρῑνω krīnō, "to separate" and grc -λογία Internal medicine is the medical specialty concerned with the diagnosis management and nonsurgical treatment of unusual or serious diseases
The Endocrine system is an information signal system much like the nervous system. The nervous system is a Network of specialized cells that communicate information about an animal's surroundings and itself However, the nervous system uses nerves to conduct information, whereas the endocrine system mainly uses blood vessels as information channels. The blood vessels are part of the Circulatory system and function to transport Blood throughout the body Glands located in many regions of the body release into the bloodstream specific chemical messengers called hormones. Hormones regulate the many and varied functions of an organism, e. g. , mood, growth and development, tissue function, and metabolism, as well as sending messages and acting on them. Human development is the process of Growing to maturity In biological terms this entails growth from a one-celled Zygote to an adult Human being Tissue is a cellular organizational level intermediate between cells and a complete organism Metabolism is the set of Chemical reactions that occur in living Organisms in order to maintain Life.
The typical mode of cell signaling in the endocrine system is endocrine signaling. Cell signaling is part of a Complex system of Communication that governs basic cellular activities and coordinates cell actions The endocrine system is an integrated system of small organs that involve the release of extracellular signaling molecules known as Hormones The endocrine system is instrumental However, there are also other modes, i. e. , paracrine, autocrine, and neuroendocrine signaling [2]. Purely neurocrine signaling between neurons, on the other hand, belongs completely to the nervous system. Neurons (ˈnjuːɹɒn also known as neurones and nerve cells) are responsive cells in the Nervous system that process and transmit information The nervous system is a Network of specialized cells that communicate information about an animal's surroundings and itself
A number of glands that signal each other in sequence is usually referred to as an axis, for example the Hypothalamic-pituitary-adrenal axis. The endocrine system is an integrated system of small organs that involve the release of extracellular signaling molecules known as Hormones The endocrine system is instrumental The hypothalamic-pituitary-adrenal axis ( HPA or HTPA axis) also known as the Limbic -hypothalamic-pituitary-adrenal axis (LHPA axis is a complex set of direct influences
Typical endocrine glands are the pituitary, thyroid, and adrenal glands. The pituitary gland, or hypophysis, is an Endocrine gland about the size of a Pea. The thyroid is one of the largest Endocrine glands in the body In Mammals the adrenal glands (also known as suprarenal glands) are the triangle-shaped Endocrine glands that sit on top of the Kidneys their Features of endocrine glands are, in general, their ductless nature, their vascularity, and usually the presence of intracellular vacuoles or granules storing their hormones. In contrast exocrine glands such as salivary glands, sweat glands, and glands within the gastrointestinal tract tend to be much less vascular and have ducts or a hollow lumen. Exocrine glands are Glands that secrete their products ( Enzymes into ducts (duct glands The salivary glands in mammals are exocrine glands that produce saliva The skin contains two different groups of sweat glands: Apocrine sweat glands and Merocrine sweat glands. A gland is an organ in an animal's body that synthesizes a substance for release such as Hormones or Breast milk, often into the Bloodstream A lumen (Lat lūmen, an opening or light (pl lumina is the inside space or lining of a tubular structure such as an artery or intestine
Other signaling can target the same cell. Autocrine signaling is a form of signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent that binds to autocrine receptors on the same cell leading
Paracrine signaling is where the target cell is nearby. Paracrine signaling is a form of Cell signaling in which the target cell is near (" Para " = near the signal-releasing cell
Juxtacrine signals are transmitted along cell membranes via protein or lipid components integral to the membrane and are capable of affecting either the emitting cell or cells immediately adjacent. In biology juxtacrine signaling is a type of Intercellular communication which is transmitted via Oligosaccharide, Lipid or Protein components
Diseases of the endocrine system are common,[3] including diseases such as diabetes mellitus, thyroid disease, and obesity. Among the hundreds of endocrine diseases (or endocrinological diseases) are Adrenal disorders Adrenal insufficiency Among the hundreds of endocrine diseases (or endocrinological diseases) are Adrenal disorders Adrenal insufficiency Diabetes mellitus (ˌdaɪəˈbiːtiːz or /ˌdaɪəˈbiːtəs/ /məˈlaɪtəs/ or /ˈmɛlətəs/ often referred to simply as diabetes ( Ancient Greek: grc The thyroid is one of the largest Endocrine glands in the body Obesity is a condition in which excess Body fat has accumulated to such an extent that health may be negatively affected Endocrine disease is characterised by dysregulated hormone release (a productive Pituitary adenoma), inappropriate response to signalling (Hypothyroidism), lack or destruction of a gland (Diabetes mellitus type 1, diminished erythropoiesis in Chronic renal failure), or structural enlargement in a critical site such as the neck (Toxic multinodular goitre). Pituitary adenomas are Tumors that occur in the Pituitary gland, and account for about 10% of intracranial neoplasms. Hypothyroidism is the disease state in humans and animals caused by insufficient production of Thyroid hormone by the Thyroid gland. Diabetes mellitus type 1 (Type 1 diabetes Type I diabetes T1D T1DM IDDM juvenile diabetes is a form of Diabetes mellitus. Erythropoiesis is the process by which Red blood cells (erythrocytes are produced Chronic kidney disease (CKD also known as chronic renal disease, is a progressive loss of renal function over a period of months or years Toxic multinodular goitre (also known as toxic nodular goitre, toxic nodular struma) is a form of Hyperthyroidism - where there is excess production of Hypofunction of endocrine glands can occur as result of loss of reserve, hyposecretion, agenesis, atrophy, or active destruction. Hyperfunction can occur as result of hypersecretion, loss of suppression, hyperplastic, or neoplastic change, or hyperstimulation. Hyperplasia (or "hypergenesis" is a general term referring to the proliferation of cells within an organ or tissue beyond that which is ordinarily seen in e
Endocrinopathies are classified as primary, secondary, or tertiary. Primary endocrine disease inhibits the action of downstream glands. Tertiary endocrine disease is associated with dysfunction of the hypothalamus and its releasing hormones.
Cancer can occur in endocrine glands, such as the thyroid, and hormones have been implicated in signalling distant tissues to proliferate, for example the Estrogen receptor has been shown to be involved in certain breast cancers. Thyroid cancer refers to any of four kinds of malignant Tumors of the Thyroid gland papillary, follicular, medullary or The estrogen receptor (ER is a member of the nuclear hormone family of Intracellular receptors which is activated by the Hormone 17β-estradiol Breast cancer is a Cancer that starts in the cells of the Breast in women and men Endocrine, Paracrine, and autocrine signalling have all been implicated in proliferation, one of the required steps of oncogenesis. Oncogenesis is the process of Malignant transformation leading to the formation of a tumor ( Tumorigenesis) [4]
