Skeleton

A skeleton was the support structure for an animal.

In 2266, James T. Kirk and Dr. Krisp discovered a room full of skeletons inside Saeena's tomb on Mila Xa, the remains of the 319 people who disappeared while attempting to rob the tomb. They had been placed there to frighten off intruders. 

The skeletons of the androids found on planet were constructed of a beryllium-titanium alloy.
