| Question | Answer |
|---|---|
| Rectus capitis posterior major | extension of the head and rotation ot the same side |
| Rectus capitis posterior major | Spinous process of C2 to Occipital Bone |
| Rectus capitis posterior minor | Spinous process of C1 to Occipital bone |
| Rectus capitis posterior minor | Extension of head |
| Obliquus capitis superior | Transverse process of C1 to Occipital Bone |
| Obliquus capitis superior | Extension of head ahnd lateral flexion to same side |
| Obliquus capitis inferior | Spinous process of C2 to Transverse process of C1 |
| Obliquus capitis inferior | Rotation of face to same side |
| Interspinalis | Spinous procees above to spinous process below |
| Interspinalis | stabilization |
| Intertransversarii | transverse process above to transverse process below |
| Intertransversarii | stabilization |
| Levatores costarum | transverse process tips of C7 to T11 --> pass inferolaterally and insert on rib |
| Levatores costarum | elevates rib |
| Multifidus | aponeurosis of erector spinae muscles, sacrum and transverse processes of lumbar, thoracic and cervical vertebrae --> spinous process of L,T, and lowC vert. |
| Multifidus | extend the vertebral column and rotates the vcertebral column contralaterally |
| Rotatores | transverse processesof C2 vertebra to the sacrum --> near lamina immed. above vert. or origin |
| Rotatores | extend the vertebral column and rotates the vcertebral column contralaterally |
| Semispinalis thoracis | Transverse processes of T7-T12 vertebrae --> spinous processes of C6-T6 vertebrae |
| Semispinalis thoracis | EXTEND the C and T regions of vert column and ROTATES the column contralaterally |
| Semispinalis cervicis | Transsverse process of T1-T6 vertebrae --> Spinous processes of C2-C5 |
| Semispinalis cervicis | EXTEND the C and T regions of vert column and ROTATES the column contralaterally |
| Semispinalis capitis | Transverse processes of C7-T6 vert --> between the sup and inf nuchal lines on occipital bone |
| Semispinalis capitis | EXTENDs head and TURNS face towards the opposite side |
| Spinalis thoracis | Spinous processes of T1-L2 vertebrae --> Spinous processes of T1-T8 vertebrae |
| Spinalis thoracis | Bilateral-EXTEND vert column; Unilateral- lateral FLEXION of vert column |
| Spinalis cervicis | Lower nuchal ligamnet and C7 spinous process --> spinous process of C2 |
| Spinalis cervicis | Bilateral-EXTEND vert column; Unilateral- lateral FLEXION of vert column |
| Longissimus thoracis | Blends wth iliocostalis; transverse processes of lumbar vertebrae --> transverse processes of T vert and inf borders of ribs (Lower 10) |
| Longissimus thoracis | Bilateral-EXTEND the vert column; Unilateral- lateral FLEXION of vert column |
| Longissimus cervicis | Transverse processes of T1-T5 vert --> transverse processes of C2-C6 vert |
| Longissimus cervicis | Bilateral-EXTEND the vert column; Unilateral- lateral FLEXION of vert column |
| Longissimus capitis | Transverse processes of C5-T5 vert --> mastoid process of temporal bone |
| Longissimus capitis | Bilateral-EXTEND the vert column; Unilateral- lateral FLEXION of vert column |
| Iliocostalis lumborum | Iliac crest and sacrospinal aponeurosis --> thoacolumbar fascia and ribs 7-12 |
| Iliocostalis lumborum | Bilateral-EXTEND vert column; Unilateral--lateral FLEXION of vert column |
| Iliocostalis thoracis | Ribs 6-12 --> ribs 1-6 and transverse process of C7 vertebra |
| Iliocostalis thoracis | Bilateral-EXTEND vert column; Unilateral--lateral FLEXION of vert column |
| Iliocostalis cervicis | Ribs 3-6 --> transverse processes of C4-C6 vertebrae |
| Iliocostalis cervicis | Bilateral-EXTEND vert column; Unilateral--lateral FLEXION of vert column |
| Splenius capitis | Nuchal ligament, spinous processes of C7-T4 vertebrae --> Mastoid process and occipital bone |
| Splenius capitis | Acting alone: Laterally BENDS and ROTATES the head (same side); Acting together: EXTEND head and neck |
| Splenius cervicis | Spinous processes of T3-T6 --> Transverse processes of C1-C3 |
| Splenius cervicis | Acting alone: Laterally BENDS and ROTATES the head (same side); Acting together: EXTEND head and neck |
