Title: Oligodendrocytes are cells in the brain that produce myelin (2 Questions)
Post by: Coltonht on Jul 15, 2019
After reading the paragraphs below, answer the questions that follow.

Oligodendrocytes are cells in the brain that produce myelin in the central nervous system. Myelin regulatory factor (MyRF) is a transcription factor that is required by oligodendrocytes in order to produce myelin. Researchers investigated the importance of MyRF by having mice learn how to run on complex wheels (there were many gaps in the wheel thus making it difficult to run on—see graph below).





When mice are learning to run on these complex wheels, what part of the brain are they primarily using?

▸ cerebrum

▸ cerebellum

▸ diencephalon

▸ brainstem

Mice that lacked the MyRF genes (P-MyRF (−/−)) and mice that had functional MyRF genes (P-MyRF (+/−)) ran on the complex wheel and their speed was recorded (see accompanying figure). What group of mice learned how to run on the complex wheel more easily?

▸ mice with nonmyelinated axons

▸ mice with myelinated axons
