D. ependymal cell. E. macrophage 6. The spinal cord begins from the A. cerebellum B. medulla oblongata. C. midbrain. D. pons E. cerebrum.

Explanation / Answer

3) voltage regulated channels can be found in the membrane that covers axons

4) the sensory neurons responsible for delivering pain to the brain are sensory neurons, motor neurons and interneurons

5) myelin is a composition of major lipids and small proteins so the myelination was done in the axons by oligodendrocyte

6) the spinal cord begins from the medulla oblongata and ends at ht secon lumbar vertebra
