Endocrine glands release (secrete) hormones into the bloodstream.
The endocrine glands include:
- Islets of Langerhans in the pancreas
Hypersecretion is when too many hormones are secreted from a gland. Hyposecretion is when too few hormones are released.
There are many types of disorders that can result when too much or too little of a hormone is released.
Disorders that may result when a particular gland does not produce the right amount of hormones include:
- Addison disease
- Adrenogenital syndrome or adrenocortical hyperplasia
- Cushing syndrome
- Renal calculi
- Excessive loss of minerals from bone
Testes and ovaries:
- Lack of sex development (unclear genitalia)
