| Erector Spinae m. which originates off the spines of lower thoracic and upper lumbar vertebrae and inserts into the spines of upper thoracic vertebrae. (be specific) | Spinalus thoracis |
| Erector Spinae m. which originates off TP's of upper thoracic vertebrae and inserts of TP's of cervical (up to C2 not including C1) | Longissimus Cervicis |
| Insertion of the middle/medial scalene m. | 1st Rib |

| Intrinsic back muscle which originates off the TP of a vertebra and inserts into the spine of one or two vertebrae above. | Rotators (Short and Long) |
| Muscle best developed in cervical region, also present in lumbar region - absent in most of the thoracic; extends vertebral column and bends column toward same side. | Intertransversarii |
| Muscle best developed in cervical region, also present in lumbar region. Absent in most of the thoracic area; act to extend the vertebral column, but does not bend it laterally? | Interspinalis |
| Muscle found throughout the length of the vertebral column; it arises from the TPs and inserts into the SP's of TWO to FIVE segments above the origin. | Multifidus |

| Muscle that depresses hyoid bone and elevates larynx. | Thyrohyoid m. |
| Muscle that depresses, retracts and steadies the hyoid bone. | Omohyoid m. |
| Muscle that elevates hyoid bone, floor of the mouth, and tongue during swallowing and speaking. | Mylohyoid m. |
| Muscle that lies immediately posterior to most of the suboccipital muscles. | Semispinalis Capitis |
| Muscle that originates from the inferior mental spine. | Geniohyoid |
| Muscle that originates from the TP's of vertebrae and inserts into SP's of vertebrae ONE segment above origin. | Short Rotators or Rotatores brevis |
| Muscle that pulls hyoid bone anterosuperiorly, shortens floor of mouth and widens pharynx. | Geniohyoid |
| Muscle which originates off the SP of axis and inserts on the TP of the atlas. | Obliquus Capitis Inferior |
| Suboccipital m. that originates off the posterior tubercle of the ATLAS and inserts into the medial part of the occipital bone. | Rectus Capitis Posterior Minor |
| Suboccipital m. which originates from the SP of the axis and inserts into area near the inferior nuchal line. | Rectus Capitis Posterior Major |
