Why is the thoracic spine less prone to injury than the cervical spine?

The thoracic spine is less prone to injury than the cervical spine primarily because it is supported by the rib cage. The rib cage provides structural stability and protection to the thoracic spine, helping to absorb forces and distribute stress during physical activities. This anatomical feature reduces the likelihood of injury in that region, especially in comparison to the cervical spine, which has a greater range of motion and is less protected.

Additionally, the thoracic vertebrae are designed to support the upper body and maintain an upright posture. This design, in conjunction with the rib cage, makes the thoracic spine inherently more stable than the cervical spine, where injuries can occur more easily due to its flexibility and the mobility required for head movement. Other factors, such as the density and strength of the bone structure and nerve endings in each region, play a role in overall spinal function and injury risk, but the supportive nature of the rib cage is a key reason why the thoracic spine is less prone to injury.
