Can weight bering exercise change the pain receptor on the nervous system to a higher level, where you start of weak and then become strong?

No, just its working: It's more likely that instead of altering your pain receptors, you're the exercises are actually making you stronger! over time, weight-bearing exercises will become easier as your muscles get bigger and/or toned in response to the increased workload! good for you! ...Read more

Is there a androgen receptor blocker that only bind to pituitary?

Is there a androgen receptor blocker that only bind to pituitary?

No: There are ARs found all over the body. It's a type of nuclear receptor, that is, it binds to T or DHT in the cytoplasm and then translocates into the nucleus. ARB's like casodex will block AR's wherever they are. Enzalutamide has a greater affinity, prevents translocation & binding to DNA. You may be talking about LHRH agonists or antagonist for prostate cancer. Firmagon (degarelix) blocks in the pituitary. ...Read more

What is the definition or description of: receptor?

What is the definition or description of: receptor?

Receptor Def: An organ, cell or molecule that accepts an outside signal and causes an internal change. Eyes receive light, touch receptors send messages to the brain when stimulated by pressure and estrogen receptors bind Estradiol causing responses of normal breast, ovary and uterus cells to rising and falling levels of the female steroid hormones. Most of the time "receptor" refers to one of the molecular typ. ...Read more
