Where are the spinal ganglia of the sacral nerves located in?
Located in the vertebral canal
The spinal ganglia of the sacral nerve are usually located within the ____________.
Where do the gray ramus communicans from the corresponding ganglion of the sympathetictrunk join?
At or immediately distal to its origin, the ventral ramus of each spinal nerve is joined by a grey ramus communicans from the corresponding ganglion of the sympathetic trunk.
Name the vertebral segment, where the ventral rami of the spinal cord contribute white rami communicant to the each corresponding sympathetic ganglion.
The ventral rami of the thoracic & the 1st & 2nd lumbar nerve contribute ________ to the corresponding sympathetic ganglia, and receive _________ from the ganglia.

False, C1/2 are larger.
