Ninja Nerds, Join us in this four part series where we have a further discussion on the adrenal gland, or also known as the suprarenal gland. In part 2 of this series we talk about the zona fasciculata, and cortisol. ***PLEASE SUPPORT US*** PATREON | https://www.patreon.com/NinjaNerdScience ***EVERY DOLLAR HELPS US GROW & IMPROVE OUR QUALITY*** FACEBOOK | https://www.facebook.com/NinjaNerdScience INSTAGRAM | https://www.instagram.com/ninjanerdscience/ ✎ For general inquiries email us at: NinjaNerdScience@gmail.com
What is ZONA FASCICULATA? What does ZONA FASCICULATA mean? ZONA FASCICULATA meaning - ZONA FASCICULATA definition - ZONA FASCICULATA explanation.

Constituent cells are organized into bundles or "fascicles". The zona fasciculata chiefly produces glucocorticoids (mainly cortisol in the human), which regulates the metabolism of glucose, especially in times of stress (e.g., part of the fight-or-flight response), it is stimulated by the hormone Adrenocorticotropic Hormone (ACTH) which is released from the anterior portion of the pituitary and axised upon this adrenal gland. This tissue also generates a small amount of weak androgens (e.g., dehydroepiandrosterone). The main source of androgens will come from the zona reticularis region. In certain animals such as rodents, the lack of 17alpha-hydroxylase results in the synthesis of corticosterone instead of cortisol. Steroid-producing adrenal tumours and hyperplasia of the zona fasciculata result in excess cortisol production and are the cause for adrenal Cushing's syndrome. The genetic disorder McCune-Albright syndrome can also present Cushing's syndrome in affected patients.

Today's video is the Bunched Ironweed (Vernonia Fasciculata). This beautiful purple flower attracts butterflies and insects. A great plant near a pond or water feature.
Native stingless bee from Eastern Amazon, Brazil. A very good honey producer.
She is half a day after 6th molt. The colours are so bright. At this stage she is getting some freaky hairs on the legs :)
