Textbook Question
Chapter 7, Problem 44CT
Mr. Harrison is an 82-year-old bedridden gentleman who has discovered a new interest in learning about his body. While being tended by the visiting nurse, he remarks that the supporting cells in nervous tissue (such as Schwann cells and oligodendrocytes) act like the rubber coating around household wiring. What does he mean by this analogy?

- A patient has been experiencing numbness and pain in their hands and feet during the winter. They were initially diagnosed with Reynauds (which is caused by an overactive sympathetic nervous system cutting off blood flow to the hands in the cold), but recently they have been experiencing issues with fine motor control in their hands, and the doctor is concerned that it could be Multiple Sclerosis.
