Detailed explanation-1: -Each rib articulates posteriorly with two thoracic vertebrae by the costovertebral joint. An exception to this rule is that the first rib articulates with the first thoracic vertebra only.
Detailed explanation-2: -Thoracic spine is considered to have a restricted range of motion (ROM) during flexion and extension compared with that of cervical and lumbar spine; ROM of thoracic spine is restricted by the rib cage.
Detailed explanation-3: -Thoracic vertebrae provide attachment points for numerous muscles: erector spinae, interspinales, intertransversarii, latissimus dorsi, multifidus, rhomboid major, rhomboid minor, rotatores, semispinalis, serratus posterior superior/inferior, splenius capitis, splenius cervicis, and trapezius.
