Final answer:
Distal and proximal are anatomical directional terms used to describe locations on the limbs in relation to the body's trunk, with proximal being closer to and distal being farther from the point of attachment.
Step-by-step explanation:
The terms distal and proximal are anatomical directional terms used to describe the positioning of structures on the limbs relative to the point of attachment or the trunk of the body. Proximal describes a position in a limb that is closer to the point of attachment or the trunk of the body, for example, the brachium (upper arm) is proximal to the antebrachium (forearm). Conversely, distal refers to a position that is further away from the point of attachment or the trunk, like how the crus (leg) is distal to the femur (thigh bone).
Distal and proximal are terms used in anatomy to describe positions relative to a specific point of attachment or the trunk of the body. Proximal refers to a position nearer to the point of attachment or the trunk, while distal refers to a position farther from the point of attachment or the trunk. These terms are commonly used to describe the position of limbs or body parts.
