Endocrine System Overview
Hormone , organic substance secreted by plants and animals that functions in the regulation of physiological activities and in maintaining homeostasis. Hormones carry out their functions by evoking responses from specific organs or tissues that are adapted to react to minute quantities of them. The classical view of hormones is that they are transmitted to their targets in the bloodstream after discharge from the glands that secrete them. This mode of discharge directly into the bloodstream is called endocrine secretion. The meaning of the term hormone has been extended beyond the original definition of a blood -borne secretion, however, to include similar regulatory substances that are distributed by diffusion across cell membranes instead of by a blood system. Hormonal regulation is closely related to that exerted by the nervous system , and the two processes have generally been distinguished by the rate at which each causes effects, the duration of these effects, and their extent; i. Advances in knowledge, however, have modified these distinctions.

The principal functions of male and female hormones are to control reproductive function and secondary sexual characteristics in their respective gender groups. Male hormones, such as testosterone, are usually referred to collectively as androgens. The female hormones consist of two principal groups: the estrogens e. Androgens, estrogens, and progestins are classified as steroid hormones; their chemical structure is similar to those of the other primary steroid groups, the glucocorticoids and mineralocorticoids see Chapter Male and female hormones are produced primarily in the gonads.
Hormones and the Endocrine System
Endocrine glands are small organs that make and release hormones into the blood stream. This is where they are located:. The thyroid gland is part of the endocrine system and produces thyroid hormones, which are important for metabolic health. The kidneys are specialised organs that ensure that unwanted substances and excess water are removed from the bloodstream. The ovaries produce and release eggs oocytes into the female reproductive tract at the mid-point of each menstrual cycle.

The following is a list of hormones found in Homo sapiens. Spelling is not uniform for many hormones. In male: spermatogenesis , enhances production of androgen-binding protein by the Sertoli cells of the testes. Inhibit immune response, towards the human embryo. Release Insulin-like growth factor 1 from liver. In male: stimulates Leydig cell production of testosterone. Stimulates contraction of cervix and vagina.
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.
Numerous glands throughout the body produce hormones. The hypothalamus produces several releasing and inhibiting hormones that act on the pituitary gland, stimulating the release of pituitary hormones. Of the pituitary hormones, several act on other glands located in various regions of the body, whereas other pituitary hormones directly affect their target organs. Other hormone-producing glands throughout the body include the adrenal glands, which primarily produce cortisol; the gonads i. Many of these hormones are part of regulatory hormonal cascades involving a hypothalamic hormone, one or more pituitary hormones, and one or more target gland hormones. For the body to function properly, its various parts and organs must communicate with each other to ensure that a constant internal environment i.
