BACK NERVES, 
here are twelve pair of back nerves: The first pair gives off a 
branch to the arm net-work. All the back nerves are distributed to 
the muscles of the back, ribs, jagged, chest, and abdominal muscles, 
and the diaphragm. The five lower pairs go to the cartilages of the 
ribs, and are called rib nerves. ie gates

The third and fourth, with some branches of the second pair, form 
the leg nerve, which passes under Poupart’s ligament, with the thigh _ 
artery, sends off branches to the adjacent parts, and descends in the 
_ direction of the tailor muscle, to the inner joint eminence of the 
__ thigh-bone, whence it accompanies the large visible vein of the leg, -

The fifth pair are joined to the first pair of sacred nerves. 
There are five pair of sacred nerves, all of which arise fr i 
: tail,-or termination of the spinal marrow; so called from their 
resemblance to the tail of a horse. The four first pair give off- 
branches to the viscera within the pelvis, and are afterwards united 
io the last loin nerve, to form a large net-work, which gives off the 
nerve ofthe hip-bone, the largest in the body. The hip ne
