question about corticosteroids

Should the release of corticosteroids from the adrenal cortex be classified as a simple neuroendocrine pathway? Thanks.

If you remember the long-term stress response pathway, this will help you get an idea of the classification of the pathway.

Hypothalamus releases corticotropin releasing hormone (CRH). This goes to the ANTERIOR PITUITARY. The anterior pituitary then releases Adrenocorticotropic Hormone (ACTH), which travels to the adrenal cortex. The Adrenal gland then releases corticosteroids.

A good way to look at the different pathways, particularly for this class, is that Simple Endocrine pathways don't really involve the hypothalamus (Examples: Insulin, Glucagon, PTH and Calcitonin mechanisms). Simple Neurohormone pathways involve the hypothalamus and the POSTERIOR pituitary (Ex: Oxytocin, ADH). And the Simple Neuroendocrine pathways involve the hypothalamus and the ANTERIOR pituitary.

Look on page 945. This is a good way to visualize the different pathways.

good luck studying!
