Q. The peripheral nervous system is divided into two divisions called A and B. A relays impulses from the CNS to skeletal muscles while the B transmits impulses from the CNS to the involuntary organs and smooth muscles of the body. B is further classified into C and D neural system.
A B C D
A Autonomic neural system Somatic neural system Sympathetic Parasympathetic
B Sympathetic Parasympathetic Autonomic neural system Somatic neural system
C Somatic neural system Autonomic neural system Sympathetic Parasympathetic
D Somatic neural system Sympathetic Autonomic neural system Parasympathetic

Solution:

The PNS is divided into two divisions called somatic neural system and autonomic neural system. The somatic neural system relays impulses from the CNS to skeletal muscles while the autonomic neural system transmits impulses from the CNS to the involuntary organs and smooth muscles of the body. The autonomic neural system is further classified into the sympathetic neural system and parasympathetic neural system.
