Explain the Autonomic Nervous System (ANS)

The autonomic or involuntary part of nervous system controls the functions of the body carried out automatically i.e. initiated in the brain below the level of cerebrum.

1) Rate and force of heart beat

2) Secretion of the glands of alimentary canal

3) Contractions of involuntary muscle

4) Size of pupil of the eyes
