Distribution of sensory (Mark level)
△ mammary papilla plan -----T4
△ nave plan---T10
△ Groin plan ---T12,L1
△ upper limb radialis桡侧---C5--7
△ forearm,hand ulnaris---C8,T2
△ cohort股前---L1—3 see fig
Distribution of sensory (Mark level)
△ leg anterior---L4--5
△ sole of foot,post-cohort股---S1--2
△ circum-anus and Sella area鞍--S3--5
That are help for localized diagnosis
Anatomy of sensory pathways
Two main pathways
▲ The dorsal colmn pathway
▲ The spinothalamic pathway
inter-or extra- spinal cord lesion
neck -tumor in spinal cord, in early of the lesion
▽ inter ----- damage from C---T--L--S and ‘saddle area’ reserved
▽extra----- S--L--T—C and ‘saddle area’ damaged.
[clinical classification]
