| Question | Answer |
|---|---|
| What does the suboccipital contents? | vertebral artery and suboccipital nerve |
| I am the inferolateral border of the suboccipital triangle. | obliquus capitis inferior |
| I am the superolateral border of the suboccipital triangle. | obliquus capitis superior |
| I am the superomedial border of the suboccipital triangle. | rectus capitis posterior major |
| Levator Costarum | has longus and brevis elevates ribs, assist in inspiration, assist with side bending of vertebral column |
| Intertransversarii | innervated by dorsal and ventral rami unilateral-aid in column side bending bilateral-stabilize column |
| Interspinales | aid in extension and rotation of vertebral column |
| 6th layer-deep minor intrinsic group | interspinalis, intertransversarii, levator costorum |
| Rotatores | has longus and brevis stabilize vertebrae and assist with local extension and rotary movts of vertebral column |
| Multifidus | stabilize vertebrae during local movt of vertebral column |
| Semispinalis | thoracic, cervicis, and capitis extends head, thoracic, and cervical regions of vertebral column, rotates them conralaterally |
| 5th layer-deep intrinsic group (deep transversospinalis) | Rotatores, Multifidus, and Semispinalis |
| Iliocostalis, Longimissus, and Spinalis | unilateral- side bend vertebral column bilateral- extends vertebral column and head, as back is flexed they control movt by gradually lengthening fibers |
| 4th layer-intrinsic intermediate layer | Iliocostalis, Longimissus, and Spinalis |
| 3rd layer-intrinsic superficial layer | splenius capitis and cervicis |
| Splenius Capitis and Cervicis | unilateral- side bend and rotate head to same side bilateral-extends head and neck |
| Thoracolumber Fascia | provides passive resistance to trunk extension |
| Serratus Posterior Inferior | innervated by ventral rami of spinal nerve depresses ribs |
| Serratus Posterior Superior | innervated by intercostal nerve elevates ribs |
| Serratus Anterior | innervated by long thoracic nerve protracts scapula and holds it against thoracic wall, rotates scapula |
| lumborum, thoracic, and cervicis regions | Iliocostalis |
| thoracic, cervicis and capitis regions | longissimus, semispinalis,and spinalis |
| 1st layer-superficial extrinsic | Trapezius, Latissimus Dorsi, Levator Scapulae, Rhomboid Major and Minor |
| Trapezius, Latissimus Dorsi, Levator Scapulae, Rhomboid Major and Minor | connects upper extremity to trunk and contral upper extremity movements |
| Trapezius | innervated by spinal accessory nerve XI elevates, retracts, and rotates scapula |
| Levator Scapulae | innervated by dorsal scapular elevates scapula and tilts glenoid cavity inferiorly |
| Latissumus Dorsi | innervated by thoracodorsal extends, adducts, and IR humerus, raises body toward arms during climbing |
| rhomboid major and minor | innervated by dorsal scapular retracts scapula and rotate it to depress gleniod cavity |
| Innervated by dorsal rami of spinal nerve | Splenius, Iliocostalis, Longimissus, Spinalis, longissimus, semispinalis, interspinalis, levator costorum |
| Innervated by suboccipital nerve | Rectus Capitis Posterior Minor and Major Obliquus Capitis Superior and Inferior |
| 2nd layer-intermediate extrinsic group (Superficial respiratory muscles ) | Serratus Anterior, Serratus Posterior Superior and Serratus Posterior Inferior |
