Flashcards in Intrinsic Back Muscles Deck (12):
1

Splenius capitis attachemnts

Origin-ligamenum nuchae and sponos prcoess of C7 to T3

Insert-lateral superior nuchal line of occipital bone and mastoid process of temporal bone

2

Spleniuscervicus attachents

Origin-spinous processes of T3 to T6

Insert-transverse processes of C1 and C2

3

Innervation of spleens captious and splines cervicus

Spinal nerves C1-C6

Posterior Ram, lateral branches

4

Splenius capitis and splenius cervicis actions

bilaterally extend cervical spine and head

Unilaterally act to flex and rotate the had to the same side

5

Semispinalis attachments

origen-transvere and articular processes of C4 to T7

attaches to occipital bone between superior and inferior nuchal lines

6

semispinalis innervation

spinal nervves (posterior rami)

7

semisinalis capitits and cervicis

capitis is always higher (there is a semispinalsis and spenius cap and cerv as well)

splenius are on top of semispinaialis
-cervicis is lower than capitis

8

semispinalis actions

bilaterally extend track and cervical spines and head as well as stabilizing craniovert joints

unilaterrly to bend had, cervical and thoracic spines to same side, and rotate them to opposite side

9

Erector spinae parts and which is most superficila/deep

illiocostalis, longissius, spinalis

iliocostalis, longissimus, spinalis
superficial deep

10

Splenuys capitis and cerviciss innervation

spinal nerves C1-C6 (posterior rami, lateral branches)

11

Erector spinae actions

Bilaterlly-extend spine

unilaterally-bend/rotate spine

12

Erector spinae attachemts

start-Basically ribs or vertebrae

end-rib or vertebrae or mastoid process
