Which of the following statements is true?
- Dendrites are myelinated.
- Clusters of cells bodies in the PNS are called nuclei.
- Bundles of neuron processes in the PNS are called tracts.
- Myelin sheaths increase the transmission of nerve impulses.
Homework Answers
Ans. Option D is the correct answer.
EXPLANATIONS:- The given statement D is the correct statement. The myelin sheath is made up of the lipid and provides the insulation for the nerve impulse conduction. The nerve impulse conduction will be very fast if they are myelinated.
The first statement is false because dendrites are not myelinated.
The second statement is false because the clusters of the cell bodies in the PNS is called as the ga ganglion.
The third statement is also false because it is called as the bundle of neuron processes in CNS is called as the tract.
