Final Answer:
The directional word meaning near the point of attachment to the trunk is proximal. Thus the correct option is (2).
Step-by-step explanation:
In anatomical terminology, the term proximal refers to a location that is closer to the point of attachment or origin. In the context of the human body, it typically denotes a position nearer to the trunk or the main part of the body. This contrasts with distal, which signifies a location farther away from the point of attachment. When considering anatomical structures such as limbs or organs, identifying whether a point is proximal or distal is crucial for accurate communication within the medical and biological sciences.Thus the correct option is (2).
For example, in the human arm, the shoulder joint is proximal to the elbow joint. This implies that the shoulder joint is closer to the point of attachment (the trunk) compared to the elbow joint. Understanding these directional terms is fundamental in fields like anatomy and physiology, as it facilitates precise communication about the relative positions of different body parts. Students and professionals in healthcare and related disciplines frequently use these terms to describe the location of anatomical structures accurately.
In summary, choosing the term proximal in this context aligns with the anatomical convention of describing positions relative to the point of attachment, providing clarity in expressing anatomical relationships.
