Which of the following organs are under dual control of the autonomic nervous system (ANS)?
A
Skeletal muscles
B
Liver
C
Heart
D
Pancreas
Verified step by step guidance1
Understand the concept of dual control by the autonomic nervous system (ANS). The ANS is divided into the sympathetic and parasympathetic nervous systems, which often have opposing effects on the same organ.
Identify the organs listed in the problem: Skeletal muscles, Liver, Heart, and Pancreas.
Recall that skeletal muscles are primarily under voluntary control by the somatic nervous system, not the ANS.
Consider the liver, which is influenced by the ANS but not typically described as under dual control in the same way as other organs.
Recognize that the heart is a classic example of an organ under dual control by the ANS, with the sympathetic system increasing heart rate and the parasympathetic system decreasing it.
