Which of the following best describes the unique characteristic and function of the enteric nervous system, as mentioned in the text?

  • A: It is a division of the parasympathetic nervous system, exclusively controlling heart rate.
  • B: It is a distinct network of neurons that exerts direct and partially independent control over the digestive tract, pancreas, and gallbladder.
  • C: It primarily regulates skeletal muscle contraction for voluntary movements.
  • D: It is responsible for transmitting sensory information from internal and external stimuli to the CNS.

Explanation

The text explicitly states that the enteric nervous system is a 'distinct network of neurons' that 'exerts direct and partially independent control over the digestive tract, pancreas, and gallbladder'. This highlights its unique autonomy compared to other parts of the autonomic nervous system.
