Questions and Answers

Which part of the nervous system acts as the primary control center for processing and transmitting information throughout the body?

  • Peripheral nervous system
  • Central nervous system (correct)
  • Somatic nervous system
  • Autonomic nervous system

What is the function of effectors in the nervous system?

  • Detect stimuli
  • Respond to stimuli (correct)
  • Transmit impulses
  • Act as control centers

What is the difference between grey matter and white matter in the brain and spinal cord?

  • Both refer to the same type of cells in the nervous system (correct)
  • White matter is found in the central nervous system, grey matter in the peripheral nervous system
  • Grey matter consists of myelinated axons, white matter comprises cell bodies
  • White matter consists of cell bodies, grey matter comprises myelinated axons
