Questions and Answers

What is the primary function of neurons in the motor system?

  • To regulate voluntary movement by transmitting signals from the CNS to muscle fibers (correct)
  • To produce hormones that regulate various bodily functions
  • To provide structural support to the nervous system
  • To transmit sensory information from the periphery to the CNS

    • What is the key distinction between the autonomic nervous system (ANS) and the peripheral nervous system (PNS)?

  • The ANS regulates involuntary functions, such as heart rate and digestion, while the PNS regulates sensory information (correct)
  • The ANS is responsible for voluntary movements, while the PNS is responsible for involuntary functions
  • The ANS is a part of the central nervous system, while the PNS is a part of the peripheral nervous system
  • The ANS is responsible for transmitting sensory information, while the PNS is responsible for motor functions

    • What is the primary role of neuroscientists studying neurons?

  • To develop new treatments for neurological disorders
  • To understand the structure and function of neurons in the nervous system (correct)
  • To identify the causes of neurological diseases
  • To develop new methods for neural transplantation
