Trapezius | T12 up to superior nuchal line and around to hit the clavical; Accessory Nerve (CN11); transverse cervical artery |
Latissimus Dorsi | medial lip of bicipital groove of humerus to spinous processes from T7 through the Sacrum; thoracodorsal nerve; thoracodorsal artery |
Levator Scapulae | from the transverse processes of C1 to C4 to the superior angle of the scapula; Dorsal Scapular Nerve; Dorsal Scapular Artery |
Rhomboid Minor | From the spinal process of C7 and T1 to medial scapular border; dorsal scapular nerve/atery |
Rhomboid Major | T2 to T5 to medial scapular border; dorsal scapular nerve/artery |
Serratus Posterior Superior | C7 through T3 to Ribs 2 through five; intercostal nerve; anterior intercostal artery |
Serratus Posterior Inferior | T11 through L3 to Ribs 9 through 12; intercostal nerve; anterior intercostal artery |
Spinotransversales Muscles | Splenius Capitis/Cervicis |
Splenus Capitis | Spinous processes of thoracocervical region to mastoid process and skull |
Splenius Cervicis | Spinous processes in thoracic regions to transverse process of the first few cervicle vertebra |
Errector Spinae Muscles | Iliocostalis, longissimus, spinalis; span 6 - 10 vertebrae |
Iliocostalis | lumborum, thoracis, cervicis; from sacrum/illium to the angles of the ribs (to rib 2) to transverse process C4 |
Longissimus | thoracis, cervicis, capitis; from sacrum to the mastoid process; connects the transverse processes |
Spinalis | thoracis, cervicis, capitis; connects the spinous processes together |
Transversospinales Muscles | Semispinalis, multifidus, rotatores; from transverse process of one to spinous process of another above |
Semispinalis | thoracis, cervicis, capitis (thickest muscle in neck); from thoracis region to occipital bone; skip 4-6 vertebrae at a time |
Multifidus | Span 2-4 vertebrae |
Rotatores | Span 1-2 vertebrae |
Segmental Muscles | Levatores Costarum; Interspinales; Transversarii |
Levatores Costarum | From transverse process to tubercle of rib below from C7 to T11 |
Interspinales | Pass between spinous processes |
Intertransversarii | between transverse processes |
Suboccipital Muscles | Rectus Capitis Posterior Major; Rectus Capitis Posterior Minor; Obliquus Capitis Superior; Obliquus Capitis Inferior |
Rectus Capitis Posterior Major | From C2 to below the inferior Nuchal Line (lateral) |
Rectus Capitis Posterior Minor | From C1 to below the inferior Nuchal Line (medial) |
Obliquus Capitis Superior | From the transverse process of C1 to between the Nuchal Lines |
Obliquus Capitis Inferior | From the spinous process of C2 to the transverse process of C1 |
Innervation of deep back muscles | dorsal rami of spinal nerves |
blood supply of deep back | dormsal branch of intercostal arteries |
what's in the suboccipital triangle | vertebral artery and the suboccipital nerve (aka dorsal ramus of C1) |
Greater Occipital nerve | dorsal ramus of C2 |
Thoracolumbar Fascia | serves as an attachment point and compartmentalization |
