Exercise can benefit several organs and tissues. This lesson examines how exercise affects bone. As part of this discussion, we will consider nutrients that affect bone health and how they act, as well as hormones that affect bone tissue. ...
The success of your nootropic stack depends on having optimal levels of testosterone and estrogen in your brain. Find out about sex hormones with the Nootropics Expert.
any of a class of steroid hormones that regulate the growth and function of the reproductive organs or stimulate the development of the secondary sexual characteristics. [1935–40] Random House Kernerman Webster's College Dictionary, © 2010 K Dictionaries Ltd. Copyright 2005, 1997, 1991 by Rand...
The mechanisms by which thyroid hormones affect bone are poorly defined, but the presence of thyroid hormone receptors on bone cells suggests that their actions may be directly mediated. Thyrotoxicosis is associated with bone loss and increased risk for fracture at the hip and possibly other sites;...
6 The absence of testosterone leads to tall males where bone growth plates do not close and growth continues due to the effects of growth hormone. The prepubertal voice remains, because the size of the laryngeal framework increases only from growth hormones and does not increase in relationship ...
bone matrix, and in addition, are responsible for the growth spurt that often occurs during adolescence. They also promote the conversion of the epiphyseal plate to the epiphyseal line (i.e., cartilage to its bony remnant), thus bringing an end to the longitudinal growth of bones. ...
By contrast, ecdysone did not affect the amount of BrdU-labeled nuclei, suggesting that the inhibitory effect observed in vivo probably proceeded from an indirect pathway. We then examined the role of growth factors known to stimulate neural stem cell/progenitor cell pr 展开 ...
These strong relationships have led to plasma and urine estrogen levels being used as intermediate end-points in the search for genes that affect breast cancer risk via their role in steroid disposition. Plasma androgen levels also show a relationship with breast cancer risk that is weakened but ...

The truth is that estrogen and progesterone are important, and a balance of both is essential to optimal health and performance. For example, estrogen affects bone health, muscle growth, and blood pressure while progesterone impacts appetite regulation, sleep quality, and brain function.[2,3...
