The great saphenous vein, the major superficial vein of the medial leg and thigh, is the longest vein in the human body. It extends from the top of the foot to the upper thigh and groin, running along the length of the lower limb. It plays an important role in returning blood from the superficial tissues of the leg to the heart.

Spinal stenosis is a narrowing of spaces in the spine (backbone) that results in pressure on the spinal cord and/or nerve roots. Some of its surgical treatments include: –
A cervical laminoplasty is often performed to relieve the symptoms of spinal stenosis. It is a surgical procedure that treats a painfully restricted spinal canal by creating more space for the spinal cord and nerve roots, immediately relieving pressure.
Cervical Corpectomy is also used as surgical treatment of spinal stenosis when a portion of the vertebra and adjacent intervertebral discs are removed for decompression of the cervical spinal cord and spinal nerves.
Foraminotomy (when the foramen, the area where the nerve roots exit the spinal canal, is removed to increase space over a nerve canal) is also used as surgical treatment of spinal stenosis. This surgery can be done alone or along with a laminoplasty.

Fructose, or fruit sugar, is a simple ketonic monosaccharide found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. It is a 6-carbon polyhydroxyketone with chemical formula of C6H12O6. Fructose was discovered by French chemist Augustin-Pierre Dubrunfaut in 1847.

Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle. The word “prokaryotic” means “before nucleus.” Prokaryotes include two groups: bacteria and another group called archaea. In contrast, eukaryotic cells have a “true” nucleus containing their DNA.
