: : 5. The umbilicus A/P projection is to the T10 vertebra and the cutaneous innervation is by the L3 spinal nerve.
: : False-the A/P projection IS to the T10 vertebra BUT the cutaneous innervation is by the T10 spinal nerve
: Agree. But..., the umbilicus projects to L3 and includes the T20 dermatome.
Well, if you are going to mess up, might as well do it right. The umbilicus vertebral projection is to L4 (check your lecture notes) along with the iliac crest. The costal margin projects to L3.
