Your left wrist is what anatomical direction from your left elbow?
Norma-Jean [14]

Answer:

The correct answer will be- distal

Explanation:

In anatomy, the anatomist defined the standard position and movement of the bones of the skeletal system by universal anatomical terminologies.

The directional position of the bones of arms and legs is represented by the proximal and distal plane.

The proximal direction represents the bone closest to the point of origin or reference while distal represents the bone closest to the farthest away from the reference.  Since the left wrist is farther from the reference or the elbow therefore, it is considered distal to the elbow.

Thus, distal is the correct answer.

  • Because of this, Darwin was inspired to consider whether natural selection can eventually result in the emergence of new species after studying the selective breeding of pigeons.
  • Darwin came to the following conclusion based on these straightforward observations:
  • In a population, some individuals would have hereditary qualities that assist them survive and reproduce (given the conditions of the environment, such as the predators and food sources present).
