Question
Chapter 14, Problem 17RA
Summary Introduction
To determine:
The working of stretch receptors.
Introduction:
Stretch receptors are responsible for the coordination of muscle activity. These can detect the stimulus of stretch in the case of muscle tissues. Stretch arc present in the aortic arch and ceratoid sinus controls pressure in the blood vessels.
