Hypothalamic-pituitary-adrenal axis - Wikipedia The hypothalamic-pituitary-adrenal axis (HPA axis or HTPA axis) is a complex set of direct influences and feedback interactions among three components: the hypothalamus, the pituitary gland (a pea-shaped structure located below the thalamus), and the adrenal (also called "suprarenal") glands (small, conical organs on top of the kidneys).. These organs and their interactions constitute the ... Hypothalamic-pituitary-gonadal axis - Wikipedia The hypothalamic-pituitary-gonadal axis (HPG axis) refers to the hypothalamus, pituitary gland, and gonadal glands as if these individual endocrine glands were a single entity. Because these glands often act in concert, physiologists and endocrinologists find it convenient and descriptive to speak of them as a single system. The HPG axis plays a critical part in the development and ...

The hypothalamus-pituitary-adrenal (HPA) axis The endocrine system is obviously a lot more complex than this, but the first diagram below gives a good representation of how the HP-axis inter-relates with three incredibly important glands - our gonads (ovaries in women and testes in men), adrenal glands, and thyroid gland:

How the Adrenal Axis Works - Geeky Medics Glucocorticoid production is regulated by the hypothalamic-pituitary-adrenal-axis. Physiology 1. Corticotropin-releasing hormone (CRH) is secreted by the hypothalamus. The release of CRH is influenced by stress levels, time of day and serum cortisol levels. 2. CRH travels in the blood and binds to specific receptors on the pituitary gland. File:Hypothalamic-pituitary-adrenal axis diagram.jpg English: Hypothalamic-pituitary-adrenal axis. ACTH, adrenocorticotropic hormone; CRH, corticotropin-releasing hormone. Hypothalamic Pituitary Axis | Endocrine System - YouTube In this video, Dr Mike explains the relationship between the hypothalamus and the pituitary gland (both anterior and posterior lobes). The Hypothalamic-Pituitary-Adrenal (HPA) Axis The combined system of CRH-ACTH-cortisol release is referred to as the hypothalamic-pituitary-adrenal axis (or HPA axis). Positive and negative feedback occurs at various sites in the brain to ensure that cortisol production stays within certain bounds, depending on current requirements and stress levels.

Hypothalamus-Pituitary-Thyroid Axis - PubMed The hypothalamus-pituitary-thyroid (HPT) axis determines the set point of thyroid hormone (TH) production. Hypothalamic thyrotropin-releasing hormone (TRH) stimulates the synthesis and secretion of pituitary thyrotropin (thyroid-stimulating hormone, TSH), which acts at the thyroid to stimulate all steps of TH biosynthesis and secretion.

The Hypothalamic-Pituitary-Adrenal Axis: A Brief History The hypothalamic-pituitary-adrenal (HPA) axis is central to homeostasis, stress responses, energy metabolism, and neuropsychiatric function. The history of this complex system involves discovery of the relevant glands (adrenal, pituitary, hypothalamus), hormones (cortisol, corticotropin, corticotropin-releasing hormone), and the receptors for these hormones.

HPA Axis & Stress Response: Hypothalamic Pituitary Adrenal Axis The hypothalamic pituitary adrenal (HPA) axis is our central stress response system. The HPA axis is an eloquent and every-dynamic intertwining of the central nervous system and endocrine system. This system works in a fairly straight-forward manner. The HPA axis is responsible for the neuroendocrine adaptation component of the stress response.

Hypothalamic-Pituitary-Adrenal System: Explanation, Function The hypothalamic-pituitary-adrenal system is the body's response to chronic stress. There are 5 phases to the HPA-axis stress response process. Cortisol also results in other changes, such as diminished memory and concentration. Long-term chronic stress is not good as it can lead to physical and mental health problems.
