edocrine system

• The endocrine system is responsible for the production and secretion of hormones, which are slower and last longer than neurotransmitters.
• Target cells only attract to certain cells in the endocrine system.
• The endocrine system consists of a network of glands that produce hormones, which pass through the bloodstream causing a change in body or behaviour.
• The pituitary gland is the master gland that controls the release of hormones from many glands.
• The anterior part of the pituitary gland releases ACTH in response to stress, stimulating the adrenal gland to produce cortisol, a hormone that helps in hushing and stress.
• The posterior part of the pituitary gland releases oxytocin, which is associated with happiness, arousal and love.
• The thyroid gland regulates the metabolic rate, protein synthesis, is involved in digestion, brain development, bone development and how your heart and muscles work.
• The thyroid gland is found in the neck.
• The adrenal medulla produces adrenaline and noradrenaline, which are involved in the fight or flight response, increasing heart rate, blood pressure, and the release of glucose and fats.
• The adrenal cortex produces corticosteroids, which release glucoses and fats for energy and suppress the immune system.
• Testosterone, produced in the testes, is responsible for muscle mass and is only found in males.
• Oestrogen, produced in the ovaries, is responsible for menstruation and pregnancy and is only found in females.
• Melatonin, produced in the pineal gland, regulates the sleep wake cycle.
