A high olecranon process locks the elbow into place when used in locomotion. This image of a human shows a dislocation of the ulna and you can see the olecranon process is low when viewed from this angle. What type of locomotion would benefit from having a high olecranon?
A. Suspensory
B. Quadrupedal
C. Vertical clinging and leaping
D. Bipedalism

The type of locomotion that would benefit from having a high olecranon is suspensory (option A).

Explanation:

Olecranon is a bony prominence or process associated with the cube bone and is found at the elbow joint in the upper extremities.

The olecranon process blocks the extension of the elbow by fitting into the socket of the humerus bone, allowing the upper limb to be firm and stable for support on elevated surfaces, climbing, or suspensory locomotion.
