Explanation:
Detailed explanation-1: -The transverse processes serve as muscle attachment sites and are used as lever arms by spinal muscles. The muscles that attach to the transverse processes maintain posture and induce rotation and lateral flexion of single vertebrae and the spine as a whole.
Detailed explanation-2: -The thoracic transverse processes project posteroinferolaterally. Each thoracic vertebra articulates with a pair of ribs. Each rib end articulates with demifacets above and below the discs to form synovial costovertebral joints as well as the thoracic transverse processes to form costotransverse joints.
