"Synthetic windpipe is used to replace cancerous one"-- NYTimes

Tissue engineering and regrowing human body parts plays a key role in my speculative medical thriller, THE LIFE AFTER LIFE CONSPIRACY, so I'm constantly on the lookout for new breakthroughs in related areas.

I've recently cited a couple of these successes: 

Synthetic windpipes and kidneys "printed" in 3-D

And,

"Lab-grown glands, eyes and brain parts"-- Mo Costandi's report on new Japanese research

Here's  a new instance, this from the New York Times this week, reporting on another successful tissue-engineered windpipe. Particularly interesting are the details of how that was done.

Previously, most implanted tracheas were based on "used" organs taken from cadavers. Those didn't always fit the recipient.

In this case, the medical team (in Sweden) worked from CT scans of the patient's own trachea to get it as close as possible.  Then a "scaffold" was fashioned from plastic (like the plastic used in that soda bottle on your table right now!), and that scaffold was "seeded" with the patient's own stem cells, taken from his bone marrow.

That seeded plastic scaffold was placed in a "bioreactor" and spun for a couple of days to get the process started, then implanted in the patient, and his body then became a bioreactor, and the cells continued to grow into place around the framework.

Now the patient is home, grateful "for a second chance at life."

What is the path of a nerve impulse? I would be quite useful if any individual can reply to that question. I'm stuck with this dilemma for last 7 days and I'm not able to locate properties response for that issue. Any reaction will be extremely appreciated. Thank you extremely significantly and have a wonderful day. Apologies for my weak english language. Cheers !
