Transverse process of cervical vertebrae
Consider a rib articulated to the thoracic vertebrae and cut off at the length of the transverse process of the thoracic vertebrae.Then the ribs correspond to the anterior tubercle of the cervical vertebra, and the transverse process of the thoracic vertebra corresponds to the posterior tubercle (10)of the cervical vertebra.The hole between the transverse process of the thoracic vertebrae and the ribs corresponds to the foramen transversarium of the cervical vertebrae.
