Endocrine glands
Definition
Endocrine glands produce hormones into the blood or lymph systems. These glands include the thyroid, parathyroid, hypothalamus, pineal, pituitary, adrenal, islets of Langerhans in the pancreas, and the gonads (testes and ovaries). The effects of these hormones may affect one organ or tissue, or the entire body.
Information
When a gland produces a substance, it is called secretion. There are many disorders that can result when too few hormones are secreted (hyposecretion), or too many are secreted (hypersecretion). Here is a partial list of disorders that may result when a particular gland does not produce the right amount of hormones.
Thyroid:
Parathyroid:
- Tetany
- Renal calculi
- Excessive loss of minerals from bone
Adrenal:
Pituitary:
Testes and ovaries:
