Which type of cell in the CNS is primarily involved in immune response?
Microglia
What is a characteristic feature of ependymal cells in the CNS?
Secreting cerebrospinal fluid
Which cell type in the CNS plays a critical role in maintaining ion balance around neurons?
Astrocytes
In the CNS, which cell type is involved in providing metabolic support to neurons?
Astrocytes
Which of the following statements about the relationship between neurons and astrocytes in the CNS is true?
Astrocytes play a crucial role in maintaining the blood-brain barrier and regulating the extracellular environment of neurons.
Which of the following statements accurately describes the function of oligodendrocytes in the CNS?
Oligodendrocytes form the myelin sheath around axons in the CNS, facilitating efficient signal transmission.
Which of the following statements accurately describes the role of microglia in the CNS?
Microglia are the resident immune cells of the CNS, playing a crucial role in immune surveillance and response to injury or infection.
Which of the following statements accurately describes the function of ependymal cells in the CNS?
Ependymal cells line the ventricular system of the brain and spinal cord, and are involved in the production and circulation of cerebrospinal fluid.
Which of the following statements accurately describes the primary function of neurons in the CNS?
Neurons are responsible for the generation, integration, and propagation of electrical signals, enabling information processing and communication within the CNS.
