The main function of the endocrine system is:

• Conducting nerve impulses

• Secretion of hormones

• Phagocytosis of bacteria

• Production of digestive enzymes

The main regulator of the endocrine system is:

• Pituitary gland

• Hypothalamus

• Pineal gland

• Adrenal glands

The pituitary gland is anatomically connected with:

• Cerebellum

• Hypothalamus

• Medulla oblongata

• Thalamus

The anterior lobe of the pituitary gland is called:

• Neurohypophysis

• Adenohypophysis

• Epiphysis

• Metahypophysis

Growth hormone (somatotropin) is secreted by:

• Thyroid gland

• Anterior pituitary lobe

• Adrenal glands

• Pancreas

Vasopressin (ADH) is synthesized in:

• Hypothalamus

• Pituitary gland

• Pineal gland

• Thyroid gland

The main function of oxytocin is:

• Increasing blood glucose

• Uterine contraction during childbirth

• Raising blood pressure

• Stimulating gastric secretion

The thyroid gland secretes:

• Adrenaline and noradrenaline

• Thyroxine and triiodothyronine

• Insulin and glucagon

• Cortisol and aldosterone

The essential element for thyroid hormone synthesis is:

• Iron

• Calcium

• Iodine

• Magnesium

Calcitonin lowers the level of:

• Blood glucose

• Blood calcium

• Blood potassium

• Blood sodium
