Q. Give the correct term for each of the following and choose the correct option from the codes given below A. Axon or dendron, covered with one or two sheaths B. Bundles of nerve fibres within the centralnervous system C. Masses of neurons that lie in the peripheral nervous system D. Masses of neurons clustered inside the central nervous system Codes
A) A-Nerve fibre, B-Tracts, C-Ganglia, D-Nuclei
B) A-Tracts, B-Nerve fibre, C-Ganglia, D-Nuclei
C) A-Ganglia, B-Nuclei, C-Tracts, D-Nerve fibre
D) A-Ganglia, B-Tracts, C-Nerve fibre, D-Nuclei
Explanation
I. A nerve fibre is myelinated or unmyelinated. Myelinated nerve fibres are enveloped with Schwann cells which form a myelin sheath around the axon at one or more times II. Tracts are the bundles of nerve fibres within the central nervous system III. Ganglia are the masses of neurons that lie in the peripheral nervous system IV. Nuclei are the masses of neurons clustered inside the central nervous system
