There is no mountain range that could be described as the backbone of the UK. The nearest is probably the Pennine range of hills but that is wholly within England and isn't in any other part of the UK.
Often described as the "backbone of England",the Pennine hills form a more-or-less continuous range stretching northwards from the Peak District in Derbyshire, around the northern and eastern edges of Lancashire and Greater Manchester, through the Yorkshire Dales past the Cumbrian Fells to the Cheviot Hills on the Anglo-Scottish border. North of the Aire Gap, the Pennines' western spur into North Lancashire forms the Bowland Fells, and south of the gap is a spur into east Lancashire, comprising the Rossendale Fells and West Pennine Moors. The Pennines are an important water catchment area with numerous reservoirs in the head streams of the river valleys.
The Pennines are known as the backbone of England. They run up the centre of northern England, from the Peak District in Derbyshire to Southern Scotland.
