<h2>a) option is correct </h2>

Explanation:

The parasympathetic nervous system is a division of the autonomic nervous system that controls the internal body organs in resting state

  • It is active all the time and promotes life by regulating the vital body functions, although the person is unconscious about all these processes
  • The parasympathetic system also has two types of nerve fibers:
  • Pre-ganglionic nerve fibers: These nerve fibers originate from the central nervous system and terminate at the ganglia of the parasympathetic nervous system
  • Post-ganglionic nerve fibers: They originate from the ganglia of the parasympathetic nervous system and terminate at the target organs, the post-ganglionic fibers are short in case of the parasympathetic system because the ganglia are present near the target organs
  • There are different processes in the body that are under the control of parasympathetic nervous system, namely, blood pressure, heart rate, respiration, digestion and urination

lakkis [162]
A little trick i learnt: The atomic number reflects how many electrons there are, and there must be an equal charge. therefore, there are the same amount of protons as there are electrons. so if it has 81 protons, we look for number 81 in the periodic table, Thallium
