Endocrine glands

Endocrine glands release (secrete) hormones into the bloodstream.

The endocrine glands include:

  • Adrenal
  • Hypothalamus
  • Islets of Langerhans in the pancreas
  • Ovaries
  • Parathyroid
  • Pineal
  • Pituitary
  • Testes
  • Thyroid
 

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:

Adrenal:

Pancreas:

Parathyroid:

Pituitary:

 

Testes and ovaries:

  • Lack of sex development (unclear genitalia)

Thyroid:
