At or immediately distal to the origin of the ventral ramus
Name the vertebral segment where the ventral rami of the spinal cord contribute white rami communicans to each corresponding sympathetic ganglion.
T1-L2 or L3

White ramus communicans
Gray ramus communicans
Name the part of the corresponding spinal nerve, where the recurrent meningeal nerve emerges.
Mixed spinal nerve
Name the part of the corresponding spinal nerve where the gray ramus communicans mostly joins.
at or immediately distal to the origin of the ventral ramus
Name the segments of the spinal cord which contain the preganglionic efferent fibers of the sympathetic nerve.

S2, S3, S4
The borders of an intervertebral foramen are:

Name the structures that are located within the intervertebral foramen.
Recurrent meningeal nerves
Name the type of neurons in the anterior gray column of the spinal cord.
Alpha, Beta, and Gamma (somatic efferent fibers)
The recurrent meningeal nerves of the corresponding spinal nerve receive one or more communications from neighboring white ramus communicans of the thoracic and upper lumbar sympathetic ganglion. True/false.
False - should be gray ramus communicans
Name all possible targets that are innervated by the recurrent meningeal nerve of the spinal nerve.
Wall of the blood vessels
