36

What does every somite level have?

a spinal cord segment

 that is associated with a vetebral cord segment

that is associated with a Spinal nerve element that gives us:  dermatome and myotome component for the dorsal ramus (back) and a dermatomr and myatome component for the ventral ramus. (body wall and limbs)

 

37

where do the spinal roots fuse and make the trunk?

not until they exit the vetebral foramen
