So we see that we have an outer portion known as the adrenal cortex and the inner portion known as our adrenal medulla. And each one of these divisions basically is responsible for creating and secreting their own set of hormones. So let's begin by focusing on the adrenal medulla. Now, the medulla is the inner portion of our adrenal gland and it is responsible for secreting those hormones that essentially help us respond to physically and emotionally stressful and challenging situations. Now, the cells of the medulla are actually connected to the sympathetic division of the autonomic nervous system and that's because these hormones that are used by this endocrine gland are also used by the nervous system as neurotransmitters. And we'll see what that means in just a moment.
