Quizplus · Accepted Answer

Glial cells are often referred to as the “supporting cells” of the nervous system. One of their primary roles is to provide structure and insulation to surrounding neurons, which helps to regulate their activity and prevent cross-talk between different regions of the brain. Additionally, glial cells can also modulate the activity of neurotransmitters, regulate the uptake of nutrients and waste products, and provide support and guidance to growing neurons.

Answer: C
 In addition to providing structural support to neurons, glial cells also play important roles in regulating metabolic activity and responding to environmental stimuli. For example, astrocytes are known to participate in the uptake of glucose and other nutrients, as well as the removal of waste products from the brain. Additionally, some glial cells, such as specialized pain-sensing cells called nociceptors, are known to respond to chemical and mechanical stimuli within the brain and transmit this information to other neurons.
