Second, medical roots generally go together according to language, i.e., Greek prefixes occur with Greek suffixes and Latin prefixes with Latin suffixes. Although international scientific vocabulary is not stringent about segregating combining forms of different languages, it is advisable when coining new words not to mix different lingual roots.
Endocrinology (from endocrine + -ology) is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones.It is also concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep ...

This is an example of a homeostatic negative feedback loop. Breakdown of the hormone. Exocytosis and other methods of membrane transport are used to secrete hormones when the endocrine glands are signaled. The hierarchical model is an oversimplification of the hormonal signaling process.
The study of the endocrine system and its disorders is known as endocrinology. The thyroid secretes thyroxine , the pituitary secretes growth hormone , the pineal secretes melatonin , the testis secretes testosterone , and the ovaries secrete estrogen and progesterone .
In forming or understanding a word root, one needs a basic comprehension of the terms and the source language.The study of the origin of words is called etymology.For example, if a word was to be formed to indicate a condition of kidneys, there are two primary roots – one from Greek (νεφρός nephr(os)) and one from Latin (ren(es)).
Endocrine disorders are often quite complex, involving a mixed picture of hyposecretion and hypersecretion because of the feedback mechanisms involved in the endocrine system. For example, most forms of hyperthyroidism are associated with an excess of thyroid hormone and a low level of thyroid stimulating hormone. [2]
