1. Supporting cells located within the CNS are collectively called __ A. Neuroglia B. Astrocytes C. Perikaryon D. Satellite cells 2.Which of the following types of cells line the ventricles and spinal cord? A. Astrocytes B. Schwann cells C. Ependymal cells D. Oligodendrocytes

1. The correct answer is A. Neuroglia. Neuroglia, also known as glial cells or simply glia, are the supporting cells located within the central nervous system (CNS). They play various roles in supporting and maintaining the function of neurons, the primary cells responsible for transmitting electrical signals in the CNS.<br /><br />2. The correct answer is C. Ependymal cells. Ependymal cells are a type of glial cell that line the ventricles of the brain and the central canal of the spinal cord. They are involved in the production and circulation of cerebrospinal fluid, which is a clear, colorless fluid that surrounds and protects the brain and spinal cord.
