What statement is NOT true regarding the spinal nerve and cord?

B. A spinal nerve can contain hundreds to thousands axons of sensory and motor neurons
C. As a spinal nerve approaches the spinal cord, it separates into ventral and dorsal roots
D. Spinal nerves exit the spinal cord through the intervertebral foramens of the vertebrae
Most neural pathways entering the spinal cord from left spinal nerves at some point desiccate (cross over) and are perceived by the right side of the cerebrum?
What statement is NOT true regarding the blood brain barrier?
A. Lipid soluble substances such as alcohol and caffeine can diffuse easily through the barrier
