Chapter 9, Problem 1RA
Summary Introduction
To determine:
The effects of denervation of a visceral organ.
Introduction:
Organs which are present in the cavities of the body are referred to as visceral organs. They are also termed as the internal organs of the body. In case an organ is deprived of nerve supply due to any cause, the organ is said to be denervated. Nerve cells are involved in the transmission of information between the brain and the organ.
