This differentiates the central nervous system from the peripheral nervous system, which consists of neurons, axons and Schwann cells. Oligodendrocytes and Schwann cells have similar functions in the central and peripheral nervous system respectively.
I really do think the cost of renting a stroller at Disney World is an outrageous amount of money. But, if you have no other choice, please be sure to add this cost into your vacation budget. The Disney World Stroller Rental fees are: SINGLE: $15.00 per day.
Rent a stroller, if you didn't bring one, so you can take a load off while traveling around the park with your kids. Disney World has single and double strollers available to rent, which also afford you a storage facility for diaper bags and snacks; taking your own food and drink saves money.
