Functionally, How Is Cardiac Muscle Tissue Controlled, Compared to That

Functionally, how is cardiac muscle tissue controlled, compared to that of skeletal muscle tissue?

A) Both cardiac and skeletal muscle tissue are controlled by somatic motor neurons.
B) Cardiac muscle tissue is controlled by pacemaker cells within the heart, while skeletal muscle tissue is regulated by somatic motor neurons.
C) Cardiac and skeletal muscle tissue are controlled by both somatic motor neurons and by pacemaker cells within the respective tissues.
D) Both cardiac and skeletal muscle tissue are controlled by pacemaker cells within the respective tissues.
E) Cardiac muscle tissue is controlled by somatic motor neurons, while skeletal muscle tissue is controlled by pacemaker cells within the tissue.
