The system endocrinien is composed by the unit of the Organe S (endocrine Glands) which have a function of Sécrétion of Hormone S such as:

1. - Épiphyse

2. - Pituitary gland and Hypothalamus
3. - Thyroid
4. - Thymus
5. - Suprarenal S
6. - endocrine Pancreas
7. - Ovary S
8. - Testicle S

Hormones of the pituitary gland and the hypothalamus

One speaks about hypothalamo-hypophyseal Complexe. The Hypothalamus, which contains secreting Neuron S, synthesizes the Ocytocine and the Hormone anti-diurétique (ADH). These Neurohormone S is transported along the Axone S until the Neurohypophyse where they are stored. They will be poured in the blood capillary at the proper time. The Hypothalamus also has some Neuron S equipped with Axone S very short which pour factors of inhibition and of release in the capillaries of the Système carries hypothalamo-hypophyseal which joined the adénohypophyse. These factors, the libérines, are:

• the hormone of salting out of the Growth hormone (GHRH)
• the Corticolibérine (CRH)
• the Gonadolibérine (FSH/LH-RH)
• the Thyréolibérine (TRH)
• the hormone of inhibition of the salting out of the Prolactin (CONK), also named Dopamine
• the Somatostatine, inhibiting the release of growth hormone (GH) and the Hormone thyréotrope (TSH)

These libérines has a positive or negative effect on the stimulines secreted by the Hypophyse:

• the Growth hormone (GH)
• the corticotrophine (ACTH)
• genital hormones, the folliculo-stimulative Hormone (FSH) and the Hormone lutéinisante (LH)
• the thyréotrophine (TSH)
• the Prolactin (PRL)
