What does the term 'distal' refer to in anatomy?

Closer to the trunk
Farthest from the trunk
Closer to the point of attachment
Not applicable to limbs

The correct answer is: Farthest from the trunk

The term 'distal' in anatomy is used to describe a position that is farther away from the trunk of the body or the point of attachment of a limb. This concept is particularly relevant when discussing the limbs, as it helps to delineate the locations of structures relative to the central axis of the body. For example, in the arm, the fingers are considered distal to the elbow, meaning they are farther away from the trunk compared to the elbow joint. Understanding this terminology is crucial for accurately discussing anatomical relationships and ensuring clear communication in medical and fitness contexts. The other terms listed, such as 'closer to the trunk,' refer to the opposite concept, which is defined as 'proximal,' while 'closer to the point of attachment' reiterates proximity rather than distance. The idea that this term is 'not applicable to limbs' is incorrect, as 'distal' is frequently used in limb anatomy to help describe limb structures accurately.
