- Descending part of trapezius musclePars descendens musculi trapeziiThe descending part of trapezius is the upper portion of the muscle, sloping from the skull and nuchal ligament to the outer clavicle.
- Dorsal parts of lateral intertransversarii lumborum musclesPartes dors. musculorum intertransversariorum lat. lumborumThe dorsal parts of the lateral lumbar intertransversarii are small slips linking the accessory process of one lumbar vertebra to the transverse process below.
- Iliocostalis lumborum muscleMusculus iliocostalis lumborumIliocostalis lumborum is the lumbar part of the outermost column of erector spinae, running from the pelvis and sacrum to the lower ribs.
- Iliocostalis thoracis muscleMusculus iliocostalis thoracisIliocostalis thoracis is the middle part of the outer erector spinae column, joining the lower rib angles to the upper rib angles.
- Interspinales lumborum musclesMusculi interspinales lumborumThe interspinales lumborum are short paired muscles joining the spinous processes of neighbouring lumbar vertebrae on each side of the interspinous ligament.
- Interspinales thoracis musclesMusculi interspinales thoracisThe interspinales thoracis are small, inconstant muscles joining adjacent thoracic spinous processes, found mainly at the top and bottom of the thoracic spine.
- Intervertebral discsDisci intervertebralesThe fibrocartilage pads between the vertebral bodies from C2 to the sacrum, each a ring of tough fibres around a soft core.
- Latissimus dorsi muscleMusculus latissimus dorsiLatissimus dorsi is the broad, flat muscle of the lower back that sweeps up to the arm and pulls it down and back.
- Longissimus thoracis muscleMusculus longissimus thoracisLongissimus thoracis is the large middle column of erector spinae in the back, running from the sacrum to the thoracic vertebrae and ribs.
- Lumbar vertebraeVertebrae lumbalesThe lumbar vertebrae are the five large, weight-bearing vertebrae of the lower back, lying below the thoracic spine and above the sacrum.
- Multifidus lumborum muscleMusculus multifidus lumborumMultifidus lumborum is the thick lumbar part of multifidus, a deep back muscle filling the groove beside the lumbar spinous processes.
- Multifidus thoracis muscleMusculus multifidus thoracisMultifidus thoracis is the thoracic part of multifidus, a deep back muscle running from thoracic transverse processes to spinous processes above.
- Nuclei pulposiThe soft, water-rich cores of the intervertebral discs, from the C2-C3 disc down to the lumbosacral disc, that spread load between the vertebrae.
- Quadratus lumborum muscleMusculus quadratus lumborumQuadratus lumborum is a flat, four-sided muscle of the posterior abdominal wall, joining the iliac crest to the twelfth rib and lumbar vertebrae.
- Rhomboid major muscleMusculus rhomboideus majorRhomboid major is a flat, diamond-shaped muscle of the upper back that ties the scapula's medial border to the thoracic spine.
- Rhomboid minor muscleMusculus rhomboideus minorRhomboid minor is a small, flat upper back muscle running from the lowest neck spines to the scapula at the root of its spine.
- Semispinalis thoracis muscleMusculus semispinalis thoracisSemispinalis thoracis is a deep back muscle of the mid-thorax, running from lower thoracic transverse processes to upper thoracic and lower cervical spines.
- Serratus posterior inferior muscleMusculus serratus posterior inferiorSerratus posterior inferior is a thin, four-sided muscle where the thoracic back meets the lumbar back, pulling on the lower ribs.
- Serratus posterior superior muscleMusculus serratus posterior superiorSerratus posterior superior is a thin, four-sided muscle of the upper back that runs from the lower neck spines to the upper ribs.
- Spinalis thoracis muscleMusculus spinalis thoracisSpinalis thoracis is the thin, innermost column of erector spinae in the back, linking lower and upper thoracic spinous processes.
- Thoracic vertebraeVertebrae thoracicaeThe thoracic vertebrae are the twelve vertebrae of the upper and middle back, each joining a pair of ribs to form the back of the thorax.
- Transverse part of trapezius musclePars transversa musculi trapeziiThe transverse part of trapezius is the middle portion of the muscle, running horizontally from the upper thoracic spines to the acromion and scapular spine.
- Ventral parts of lateral intertransversarii lumborum musclesPartes ventrales musculorum intertransversariorum lateralium lumborumThe ventral parts of the lateral lumbar intertransversarii are small slips joining the transverse processes of adjacent lumbar vertebrae at the side of the spine.
