Assertion and Reason
Directions: The following question has two statements, Assertion and Reason.
Answer the question by choosing any one of the four responses.
Assertion: Brain and spinal cord are called modulators.
Reason: Their neurons receive a stimulus and set up a sensory impulse.

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
If Assertion is true but Reason is false
If Assertion is false but Reason is true

2)The motor fibres running from the cerebellum to the spinal cord cross over each other at the junction of pons and medulla.
MY QUESTION IS , SPINAL CORD HAS 31 SEGMENTS WITH A PAIR OF NERVES ARISING FROM EACH SEGMENT. THEN HOW DO THESE NERVES PASS THROUGH THE SPINAL CORD ? AND ARE THEY MOTOR NERVES OR SENSORY NERVES?
