1

suboccipital region

superior part of back of neck
inferior to occipital region of head, including posterior aspects of C1 and C2 vertebrae

2

suboccipital triangle area

lies deep to trapezius and semispinalis capitis muscle

3

four muscles in suboccipital region

rectus capitis posterior major and minor
obliquus capitis superior and inferior

4

innervation of suboccipital tegion

suboccipital nerve: posyerior ramus of C1

5

rectus capitis posterior major origin

spinous process of C2 vertebra

6

rectus capitis posterior major insertion

lateral part of the inferior nuchal line of occipital bone

7

rectus capitis posterior minor origin

posterior tubercle on the posterior arch of C1 vertebra

8

rectus capitis posterior minor insertion

medial third of inferior nuchal line

9

obliquus capitis inferior origin

spinous process of C2 verterba

10

obliquus capitis inferior insertion

transverse process of C1 vertebra

11

only muscle with capitis that doesnt attach to cranium

obliquus capitis inferior

12

obliquus capitis superior origin

transverse process of C1

13

obliquus capitis superior insertion

occipital bone between superior and inferior nuchal lines

14

action of muscles of suboccipital region

postural
act on head

15

boundaries and contents of suboccipital triangke

superomedially: rectus capitis posterior major
superolaterally: obliquus capitis superior
inferolaterally: obliquus capitis inferior
floor, posterior atlanto-occipital membrane and posterior arch of C1
Roof: semispinalis capitis
contents: vertebral artery and suboccipital nerve

16

back sprain

ligamentous tissue involved without dislocation or fracture

17

back strain

some defree of stretching or microscopic tearing of muscle fibers

18

myelography

radiopaque contrast study
visualization of spinal cord and spinal nerve roots

19

computerized tomography

differentiates between white and gray matter of brain and spinal cord
