Levator Scapulae
N- Dorsal scapular nerve, ventral ramus C5 plus ventral ramus C3, C4
Rhomboid Major
N- Dorsal Scapular Nerve, ventral ramus C5 plus ventral ramus C4
Rhomboid Minor
N- Dorsal scapular nerve, Ventral ramus C5 plus ventral ramus C4
Splenius Capitis
N- Dorsal rami C3-C5
A- Laterally flex head & rotate face to side; BILATERALLY extend head
Splenius Cervicis
N- Dorsal rami C5-C7
A- Laterally flex & rotate neck; BILATERALLY extend neck
Iliocostalis Lumborum
N- Dorsal rami lower T, all L
A- Extension, lateral fexion, rotation of L spine; lateral movement of pelvis
Iliocostalis Thoracis
N- Dorsal rami T1-T6
A- Extension, lateral flexion T spine
Iliocostalis Cervicis
N- Dorsal rami T1, T2, rarely C8
A- Extension, lateral flexion, rotation lower C spine
Longissimus Thoracis
N- Dorsal rami T & L nerves
A- Lateral flexion T spine & ribs (L spine inadvertently); BILATERALLY act in extension of T & L spine, hold T & L spine erect (increases L lordosis); lateral movements of pelvis
Longissimus Cervicis
N- Dorsal rami C4-C8; T1-T2
A- Lateral flexion of neck; BILATERALLY extend neck
Longissimus Capitis
N- Dorsal rami C1-C3, sometimes C4
A- Rotate & laterally flex head; BILATERALLY extend head
Spinalis Thoracis
N- Dorsal rami T & upper L
A- Extend T spine
Spinalis Cervicis
N- Dorsal rami C
A- Lateral flexion & rotation of C spine; BILATERALLY extend neck
Spinalis Capitis
N- dorsal rami lower C, upper T
A- Lateral flexion & rotation of head; BILATERALLY extend head
Semispinalis Thoracis
N- Dorsal rami T1-T6
A- Extension, rotation & lateral flexion of upper T & lower C spine; BILATERALLY extend T spine
Semispinalis Cervicis
N- Dorsal rami C6-C8
A- Extension, rotation & lateral flexion of C spine; BILATERALLY extend neck
Semispinalis Capitis
N- Dorsal Rami C1- C6
A- Turns face to side; BILATERALLY extends head (neck inadvertently)
Multifidus
N- Dorsal rami C3-C8, T1-T12, L1-L5, sometimes S1
Rectus Capitis Posterior Major
N- Suboccipital nerve, Dorsal ramus C1
A- Turns face to side; BILATERALLY extends head
Rectus Capitis Posterior Minor
N- Suboccipital Nerve, dorsal ramus C1
A- Extends head
Obliquus Capitis Superior
N- Suboccipital Nerve, Dorsal ramus C1
Lateral flexion of head; BILATERALLY extends head
Obliquus Capitis inferior
N- Suboccipital Nerve, Dorsal ramus C1
A- Turns face to side
Quadratus Lumborum
N- Ventral Rami T12, L1-L3 or L4
Steadies origin of diaphragm; when pelvis is fixed, it will laterally flex the L spine; BILATERALLY extends the L spine. stabilize & depress the 12th rib
Serratus Posterior Superior
N- intercostal Nerves, Ventral Rami T2-T5
A- Elevates upper 5 ribs in inspiration
Serratus Posterior Inferior
N- Intercostal Nerves, Ventral rami T9-T11
Subcostal nerve, Ventral ramus T12
A- Draws lower 4 ribs down & back; forced inspiration
Longus Colli
N- Ventral Rami C2-C6, sometimes C7
A- Flexion & extension of neck; rotation to the contralateral side
Longus Capitis
N- Ventral Rami C1-C3
A- Flex the head
Rectus Capitis Anterior
N- Ventral rami C1, C2
A- Flex the head
Rectus Capitis Lateralis
N- Ventral rami C1, C2
A- Laterally flex the head to ipsilateral side
Anterior Scalene
N- Ventral rami C2-C6
Middle Scalene
N- Ventral rami C3-C8
Posterior Scalene
N- Ventral rami C6-C8
