Movement in his lower extremities

Sensation in his left lower extremities

Control of the left section of his lower body

Sensation in the right section of his upper body

Sensation in the right section of his upper body

The first cervical vertebrae is called the atlas (C1)
The spinal cord runs through the cervical vertebrae.

Ventral root means motor root, so this nerve affects the movement.
Right root controls movement in the right side of the body because the point where the 2 fibersof the spinal cords switch (decussation of pyramids) lies above the atlas.

just to make sure is it Movement in his lower extremities. I think im over thinking it

thomaster · Answer

Well you are sure that it will affect the control of muscles, so it cannot be B or D.

The right side of the ventral root is damaged right below the head in his neck.
I would say it'll affect movement in the right section of his lower body, but that's not an option. If I'd get this question I'd go for C, because it's unlikely he'll lose the movement in all his lower extremities. I'm not 100% sure though, this is not my field of expertise in biology :P
