2 types: vertebral and intervertebralVertebral foramina
Thoracic spine Lumbar spine
LATIN Foramen vertebrale
Vertebral foramen spinal cord and nerve roots pass
through
LATIN Foramen intervertebrale
Intervertebral foramen Passage of spinal nerves and intervertebral arteries which
supply the roots and spinal cord.
Lumbar spine
Costal articular surfaces3 different types of
LATIN Fovea costalis superior
Superior costal fovea
Articulate with the heads of the
ribs.
LATIN Fovea costalis inferior
Inferior costal fovea
Thoracic spine
Articulate with the heads of the
ribs.
LATIN Fovea costalis superior
Superior costal fovea
LATIN Fovea costalis inferior

T11 and T12 have no articular facets on their transverse
processes.LATIN Fovea costalis processus transversi
