Adeno-hypophysial hormones are hormones that are produced and secreted by the anterior lobe of the pituitary gland. These hormones include growth hormone (GH), adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and prolactin. These hormones regulate various functions within the body, including growth, metabolism, reproduction, and lactation.
Neuro-hypophysial hormones, on the other hand, are hormones that are produced and secreted by the posterior lobe of the pituitary gland. The two main neuro-hypophysial hormones are oxytocin and antidiuretic hormone (ADH). Oxytocin is involved in uterine contractions during childbirth and stimulates milk ejection during breastfeeding, while ADH regulates water balance and controls the amount of water reabsorbed by the kidneys.
The adrenal medulla is the inner part of the adrenal gland, which is located on top of the kidneys. The adrenal medulla produces and releases hormones called catecholamines, mainly adrenaline (epinephrine) and noradrenaline (norepinephrine). These hormones play a significant role in the body's response to stress, as they increase heart rate, blood pressure, and energy availability, preparing the body for a fight-or-flight response.
