What is adrenal axis?
The hypothalamic-pituitary-adrenal axis is a complex system of neuroendocrine pathways and feedback loops that function to maintain physiological homeostasis. Together, these changes can potentially lead to a disruption in neuroendocrine, behavioral, autonomic, and metabolic functions in adulthood.
What is a hormonal axis?
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 …
What is Hypothalamo Hypophyseal axis?
The hypothalamic-pituitary-adrenal axis, or HPA axis as it is commonly called, describes the interaction between the hypothalamus, pituitary gland, and adrenal glands. The hypothalamus and pituitary gland are located just above the brainstem, while the adrenal glands are found on top of the kidneys.

What is the stress axis?
The three main components of the stress response axis are the hypothalamus in the brain, the pituitary right next to the brain and the adrenal glands near the kidneys.
What is hypothalamic pituitary adrenal axis suppression?
Hypothalamic—pituitary—adrenal (HPA) axis suppression is a form of tertiary adrenal insufficiency caused by abrupt discontinuation of “chronic” glucocorticoid administration or of endogenous cortisol excess.
What is the thyroid axis?
The thyroid axis is comprised of thyrotropin-releasing hormone (TRH) at the level of the hypothalamus which stimulates the pituitary to release thyrotropin (TSH). TSH in turn stimulates the thyroid to secrete the pro-hormone thyroxin (T4) and to a lesser extent the receptor active hormone tri-iodothyronine (T3).
What is the growth hormone axis?
The hypothalamic–pituitary–somatotropic axis (HPS axis), or hypothalamic–pituitary–somatic axis, also known as the hypothalamic–pituitary–growth axis, is a hypothalamic–pituitary axis which includes the secretion of growth hormone (GH; somatotropin) from the somatotropes of the pituitary gland into the circulation and …
What is a thyrotropin hormone?
Thyrotropin-releasing hormone is the master regulator of thyroid gland growth and function (including the secretion of the thyroid hormones thyroxine and triiodothyronine). These hormones control the body’s metabolic rate, heat generation, neuromuscular function and heart rate, among other things.
What does the term somatotropic mean?
promoting growth
Medical Definition of somatotropic : promoting growth somatotropic activity.
Is Somatotropic cells a basophil?
The acidophils are the progenitors for both the somatotropes (GH producing) and lactotropes (PRL producing), while the basophils give rise to cells that specialize to produce adrenocorticotropic hormone, thyroid-stimulating hormone, follicle-stimulating hormone, or luteinizing hormone (Chatelain et al., 1979).
