Visceral Effectors

Chapter 9, you may remember, contrasted the Somatic Nervous System (SNS) with the Autonomic Nervous System (ANS). The SNS serves the gross body soma, which mainly features the skin, bones, joints, and skeletal muscle fibers as somatic effectors. Brief mention was also made about the ANS serving the visceral target organs or "gut" effectors. These visceral effectors include smooth muscle, cardiac muscle, and glands.

Well, Chapter 10 covered the glandular type of visceral effectors. Now, isn't it high time that we begin discussing the other two types of visceral effectors within the walls of our "guts" (viscera or internal organs) - cardiac muscle tissue and smooth muscle tissue? The location of cardiac muscle tissue leads us to the heart, while the search for smooth muscle tissue guides us to the major blood vessels.
