Which of the following statements accurately describe components and functions within the nervous system, based on the provided text? Select all that apply.

  • A: The central nervous system (CNS) can include a brain or simpler clusters called ganglia, and is responsible for sorting, processing, and integration of information.
  • B: The peripheral nervous system (PNS) consists of neurons that carry information into and out of the CNS.
  • C: Nerves are bundles formed by the axons of neurons.
  • D: Glial cells (glia) are specialized neurons responsible for transmitting nerve impulses across synapses.
  • E: Neurons with highly branched axons primarily function to receive input through tens of thousands of synapses.

Explanation

The text states: "In many animals, the neurons that carry out sorting, processing, and integration are organized in a central nervous system CNS , which may include a brain or simpler clusters called ganglia." Option A . "The neurons that carry information into and out of the CNS constitute the peripheral nervous system PNS ." Option B . "When grouped together, the axons of neurons form the bundles we call nerves." Option C . Option D is incorrect as glia are supporting cells, not neurons that transmit impulses. Option E is incorrect because highly branched dendrites receive input, while highly branched axons transmit information.
