ANSWER: The origin of the pain is from the intervertebral disks of the lumbosacral spine.
EXPLANATION:
Sciatica is pain in the lower extremity resulting from irritation of the sciatic nerve.
The sciatic nerve is the largest nerve in the body and begins from nerve roots in the lumbar spinal cord in the low back and extends through the buttock area to send nerve endings down the lower limb.
Sciatica is caused by irritation of the root(s) of the lower lumbar and lumbosacral spine. Additional common causes of sciatica include: Lumbar spinal stenosis (narrowing of the spinal canal in the lower back) Degenerative disc disease (breakdown of discs, which act as cushions between the vertebrae).
The Cusichaca Andina is the name of an organization, which is attempting to preserve a small, pink potato from the Andes, known as huana. It is considered one of the perfect crops for uncertain times, as it resists extreme rain, frost, and drought. It can be stored for two to three years.
The organization is also trying to revive the irrigation facility, which Incas utilized in the Andean region, and researching other conventional crops, like amaranth, quinoa, squashes, and potatoes.
