Which of the following statements regarding the nervous system is correct?
1 The nervous system is a rapid communication system made up of one cell type
2 The central nervous system coordinates inputs from other nerves
3 Nerves are made up of bundles of dendrites of neurones
4 The central nervous system is made up of the brain and spine
5 Nerves in the arms and legs are called effectors
6 Conditions affecting the myelin sheath cause impulses to travel slower
7 Dendrites allow connections to other neurones
A 1, 5 and 7
B 1, 5 and 6
C 2, 4 and 6
D 2, 6 and 7
E 3, 4 and 5
The answer they’ve given is D, but why is C wrong?
I think because the spinal cord isn’t mentioned!
Cause the CNS consists of brain and the spinal cord nerves and the PNS consists of cranial and spinal nerves.
But I think this is not a good question.
yeah, probably. thankyou!
Btw. Where did you see this question???
according to my research, spine contains bones, muscles, tendons, and other tissues that covers the spinal cord. while spinal cord is a column of nerve, so they are different.
HOWEVER, I somehow can’t figure out number 3 here, off regard the total options. dendrites ARE included in the neurons , does this mean it is ONLY dendrites that shape neurons? it is vague
on a site called BMAT ninja
no that statement is incorrect as it is bundles of axons that make up nerves not dendrites
