Final answer:
The wrist is naturally curved laterally from contact surfaces due to the carrying angle, a 5-15 degree lateral deviation of the forearm from the arm that facilitates free movement and carrying objects without hitting the hip. This angle is pronounced in females due to their wider pelvis.
Step-by-step explanation:
The wrist is naturally curved laterally from any contact surface when the arm is in the anatomical position. This is due to the carrying angle, a natural deviation of the forearm, ranging from 5-15 degrees, from the straight line of the arm when the elbow is fully extended and the palms are facing forward. This angle is instrumental for the free movement of the forearm and hand, allowing an individual to swing their arms or carry objects without interference from the hip. Notably, the carrying angle is larger in females, which is an adaptation to accommodate a wider pelvis.
