where are the transverse processes of the thoracic vertebrae

A

at the junction of the pedicle and lamina

20
Q

what is a costovertebral joint

A
20
Q

what is the costotransverse joint

A

tubercle articulates with the transverse process of the vertebrae

20

Major distinguishing feature are the
facets for articulations with the ribs

A
21

an LPO 75 degree oblique demonstrates what

A

the right zygapophyseal joint

29

which vertebrae has the largest bodies

A

lumbar
specifically L5

29
