EXPERIMENT INFORMATION

Vertebral Body Strength of Rat Spinal Columns (COS 1129-1)
Principal Investigator
Research Area:
Bone and calcium physiology
Species Studied
Scientific Name: Rattus norvegicus Species: Rat Strain: Wistar

Description
Objectives:

This investigation undertook a comparative analysis of biomechanical property data of rat vertebral bodies following space flight exposure. This study was to shed light on the effects of environment, relative vertebral body position, and loading rate on groups of rats sacrificed immediately at spacecraft recovery (R-0), and six (R+6) and twenty-nine days (R+29) postflight.
