Verified step by step guidance

Understand the anatomical directional terms: 'proximal' refers to a location closer to the trunk or point of origin, while 'distal' refers to a location farther from the trunk or point of origin. 'Lateral' refers to a position away from the midline of the body, and 'medial' refers to a position closer to the midline.

Consider the purpose of applying electrodes. Typically, electrodes are applied to areas where electrical signals can be effectively detected or transmitted, which often involves the distal portion of the limbs (e.g., hands or feet) as they are farther from the trunk and have more accessible muscle groups.

Evaluate the options provided: The 'proximal portion' is closer to the trunk, which may not be ideal for detecting signals from extremities. The 'distal portion' is farther from the trunk and often used for electrode placement. The 'lateral portion' and 'medial portion' describe positions relative to the midline but do not specify proximity to the trunk.

Determine why the 'distal portion' is the correct answer: It is commonly used in electrode placement because it provides better access to muscles and nerves in the extremities, which are key for detecting electrical activity.

Conclude that understanding anatomical directional terms and their relevance to electrode placement is essential for interpreting this type of question in Anatomy & Physiology.
