WebThe hypothalamic-pituitary-thyroid axis (HPT) is responsible for controlling the synthesis and secretion of two thyroid hormones: triiodothyronine (T3) and tetraiodothyronine or … The hypothalamic–pituitary–thyroid axis (HPT axis for short, a.k.a. thyroid homeostasis or thyrotropic feedback control) is part of the neuroendocrine system responsible for the regulation of metabolism and also responds to stress. As its name suggests, it depends upon the hypothalamus, the pituitary … See more Thyroid homeostasis results from a multi-loop feedback system that is found in virtually all higher vertebrates.

Environment can have large impact on the HPG axis. For example, women with eating disorders tend to have oligomenorrhea and secondary amenorrhea. Starvation from anorexia nervosa or bulimia causes the HPG axis to deactivate causing women's ovarian and uterine cycles to stop. Stress, physical exercise, and weight loss have been correlated with oligomenorrhea and secondary amenorrhea. Similarly environmental factors can also affect men such as stress caus… WebAug 3, 2024 · How to Remove Axis Labels in ggplot2 (With Examples) You can use the following basic syntax to remove axis labels in ggplot2: ggplot (df, aes(x=x, y=y))+ geom_point () + theme (axis.text.x=element_blank (), #remove x axis labels axis.ticks.x=element_blank (), #remove x axis ticks axis.text.y=element_blank (), #remove … coalesce in aws
