Certain neoplasms of non-endocrine tissues in both animals and humans either secrete hormones or molecules that share chemical and/or biological characteristics with the “native” hormones secreted by an endocrine gland. Most of the humoral substances secreted by non-endocrine tumors are peptides rath...
Also, the barrier is not as restrictive to molecules as that in the testis and will allow more substances into the ductular fluid, providing the potential for direct toxicity to the sperm. Vas Deferens The vas deferens (ductus deferens) is a thick- walled convoluted tube that is continuous ...
The hypothalamus is arguably the most essential of the endocrine system. By alerting the pituitary gland to release certain hormones to the rest of the endocrine system, the hypothalamus ensures that the internal processes of your body are balanced and working as they should....
and the pineal gland, adjust the levels of various substances in the blood and regulate metabolism, growth, the sleep cycle, and other processes. Organs such as the pancreas also secrete hormones as part of the endocrine system. Secondary endocrine organs include the gonads, kidneys, and thymus...
secretes gonadotropins in response to GnRH from the hypothalamus to produce an effect on the ovary. By this means, the pituitary acts as an endocrine intermediary between the brain and the gonads. Hormone feedback regulates the rate of secretion to maintain regular ovulation and coordinate sexual ...
Hormones Are Produced by Glands That Make Up the Endocrine System Glands are organs that secrete substances. Major hormone-secreting glands in the body include: the pituitary gland, hypothalamus, thymus, adrenal glands, pancreas, thyroid, ovaries, and testes. (2) “The body’s network of hormon...
Bisphenol a as endocrine disruptor chemical: mechanisms of action BPA is a chemical mainly used as a monomer in the manufacturing of polymers, in particular polycarbonate resins, but also epoxy polyester, polysulfone and polyacrylate resins, and flame retardants [11,12,13]. Since the polycarbonate ...

Hence these were internal (“endocrine”) secretions, unlike the chemical substances secreted into ducts leading to a target tissue, for example, salivary glands into the cheeks; pancreatic enzymes into the duodenum (“exocrine”). Cushing disease was associated with hypertrophy of the adrenal cortex...
