Question

Quizplus · Accepted Answer

Glia cells are a type of cell found in the brain and nervous system. They play a variety of roles, including providing support and protection to neurons, regulating neurotransmitter levels, and helping to form the blood-brain barrier. Option A is incorrect as Descartes' view of reflexes had to do with the interaction between mind and body, not glia. Option B is incorrect as it conflates a brain scan technique (PET scan) with a type of cell. Option D is incorrect as it refers to the synaptic cleft or gap between neurons, which is not a type of cell.
