Tenth Thoracic Vertebra T10, Posterior View

Description

Centered in the mid thoracic column, the tenth thoracic vertebra (T10) is highlighted in posterior view, with the spinous process projecting posteriorly and the laminae converging toward the midline. Lateral to the vertebral arch, the transverse processes extend bilaterally, and the superior and inferior articular processes frame the zygapophysial (facet) joints. At this level the inferior articular facets begin to reorient toward the more sagittal lumbar pattern, an observable transition when comparing T9 through T12 in the same posterior alignment. Adjacent thoracic, lumbar, and sacral segments remain visible as stacked vertebrae above and below. Facet orientation at T10 is not an academic detail, it shapes regional biomechanics and the way pain patterns can behave across the thoracolumbar junction. As the inferior articular processes shift from a thoracic, more coronal bias toward a lumbar, more sagittal alignment, coupled motion changes and facet loading increases during extension and rotation. This matters when correlating axial back pain with zygapophysial arthropathy, planning fluoroscopy-guided medial branch blocks at the lower thoracic levels, or interpreting why transitional segments can feel stiff and then fail under repetitive torsion. Small changes. Real consequences. Use this posterior T10 reference in gross anatomy and osteology teaching to anchor segment identification, and in clinical anatomy modules that compare thoracic versus lumbar facet planes. It also fits well in spine chapters for radiology and orthopaedic texts where vertebral level localization, facet joint morphology, and thoracolumbar transition mechanics need a clean posterior bony view.
