Which bones articulate with the humerus?
A
Femur and tibia
B

C
Pelvis and fibula
D
Scapula and ulna
Verified step by step guidance1
Begin by identifying the location of the humerus in the human body. The humerus is the long bone in the upper arm, extending from the shoulder to the elbow.
Understand the concept of articulation in anatomy, which refers to the connection between bones at a joint. The humerus articulates with other bones at both its proximal and distal ends.
At the proximal end, the humerus articulates with the scapula. This forms the shoulder joint, known as the glenohumeral joint, where the head of the humerus fits into the glenoid cavity of the scapula.
At the distal end, the humerus articulates with the ulna and the radius. This forms part of the elbow joint, where the trochlea of the humerus connects with the trochlear notch of the ulna, and the capitulum of the humerus connects with the head of the radius.
Review the options provided in the problem and identify the correct pair of bones that articulate with the humerus: the scapula and the ulna.
