Multiple Choice

Why are electrodes typically applied to the fleshy part of a limb during studies of the autonomic nervous system?

Because the skin is thinner over the fleshy part

To stimulate bone tissue directly

To avoid stimulating the autonomic nervous system

To ensure better electrical contact and minimize interference from bones

Verified step by step guidance

Understand the purpose of electrodes in studies of the autonomic nervous system: Electrodes are used to measure electrical activity or stimulate specific tissues, and their placement is crucial for accurate results.

Recognize the importance of electrode placement: Electrodes are typically applied to the fleshy part of a limb because this area provides better electrical conductivity due to the presence of muscle and soft tissue, which are more conductive than bone.

Consider the role of bone tissue: Bone is less conductive and can interfere with electrical signals, making it less ideal for electrode placement. Placing electrodes on the fleshy part minimizes interference from bones.

Evaluate skin thickness: While skin thickness can vary across the body, the fleshy part of a limb often has sufficient soft tissue to ensure better electrical contact, which is essential for reliable measurements or stimulation.

Conclude the reasoning: The correct answer is that electrodes are applied to the fleshy part of a limb to ensure better electrical contact and minimize interference from bones, which aligns with the principles of effective electrode placement in physiological studies.
