The endocrine system regulates growth, development and reproduction and augments the body’s capacity for handling physical and psychological stress. The adrenal medulla secretes catecholamines, hormones that help your body respond to stress. Where the nervous system acts quickly (virtually instantly) delivering messages by nerve impulses, the endocrine system has a slower but longer lasting response which compliments the nervous system. The nervous and endocrine systems also work together to initiate and control movement, and all the physiological processes movement involves. The activity of the pituitary gland is however controlled by the hypothalamus which as well as being an endocrine gland, is also part of the nervous system.Īlong with the nervous system, the endocrine system coordinates the body’s functions to maintain homeostasis during rest and exercise. The pituitary gland is known as the ‘master gland’ because its secretions control the activity of other endocrine glands. The endocrine system is linked to the nervous system by effects of the hypothalamus on the pituitary gland, as seen in the adjacent image.
