Question

Quizplus · Accepted Answer

Mechanical and chemical receptors that control digestive activity are located in the walls of the tract organs. This is where sensory neurons are activated by stretching, presence of certain substances, pH, and other factors that affect the organs' muscular and glandular activities. The pons and medulla are involved in regulating the digestive activity, but they do not contain the receptors themselves. Glandular tissue lines the organ lumens, but it does not contain the receptors either. The esophagus is not the only part of the tract that needs to change to accommodate food passage, so the receptors are not limited to this area.
