Which bone connects the shoulder to the elbow?

The humerus is the bone that connects the shoulder to the elbow. It is the long bone of the upper arm, extending from the shoulder joint, where it articulates with the scapula, down to the elbow joint, where it meets the radius and ulna of the forearm. This structural arrangement allows for a range of motions at the shoulder and elbow, facilitating various activities such as lifting, throwing, and pushing.

In contrast, the other options represent bones located in different parts of the body. The pelvis is part of the lower body and connects the trunk to the legs, while the tibia and femur are bones found in the lower limb, specifically the leg and thigh, respectively. Therefore, they do not connect the shoulder to the elbow, making humerus the only correct choice in this context.
