The thoracic vertebra represents a crucial component of the spinal column, specifically designed to support the upper body while providing attachment points for ribs. This detailed lateral view illustration demonstrates the unique anatomical features that distinguish thoracic vertebrae from cervical and lumbar vertebrae, highlighting their specialized structure for both spinal support and thoracic cage formation.
Essential Components of Thoracic Vertebral Anatomy
Superior Articular Process The superior articular process extends upward to connect with the vertebra above. This process contains facets that form joints essential for spinal movement and stability.
Costal Facet The costal facet is a specialized articulation point for rib attachment. This unique feature distinguishes thoracic vertebrae from other vertebral types and enables ribcage formation.

Spinous Process The spinous process projects posteriorly and serves as an attachment point for muscles and ligaments. In thoracic vertebrae, these processes are particularly long and angle downward.
Body The vertebral body forms the weight-bearing portion of the vertebra. This solid, cylindrical structure increases in size from superior to inferior thoracic vertebrae.
Demi Facet The demi facets are partial articulation points located on the vertebral body. These surfaces join with adjacent vertebrae to form complete facets for rib attachment.
Inferior Articular Process The inferior articular process extends downward to connect with the vertebra below. This process contains facets that complement those of the superior articular process.
