2
Q

serratus posterior inferior a o n

A

depress ribs? inferior rib borders 8-12, anterior rami t9-t12

3
Q

name thetwo spinotransversale muscles

A

splenius capitus, splenius cervices,

4
Q

action of the splenii (spinotransversales)

A

bilaterally extend neck, unilaterally rotate ipsi.

5
Q

erector spinae muscles (3)

A

spinales, illiocostale, longissimus

6
Q

action of erector spinae muscles

A

posture, extension, but some bending and rotation

7
Q

splenius capitus o i

A

lig nuchae and spinous process of c7-t4; skull below the lateral 1/3 of the nuchal line and mastoid process

8
Q

splenius cervecis o i

A

spinous process t3-t6; transverse process c1-c3

9
Q

illiocostales, o i

A

iliac crest/ or lumbar fascia or angles of ribs (TC)– angles of ribs (l/t) transverse processes (cervical)

10
Q

longissimus o i – thoracis cervicis capitus

A

transverse processes, transverse process or mastoid (capitus)

11
Q

spinales o, i

A

spinous processes– blends w semi spinales capites or nuchal line

12
Q

transversospinales mucsles (4)

A

semispinales capitus, semispinales thoraicis, rotatores thoracis, multifidus

13
Q

transversospinales o i

A

transverse process (or lamina) to spinous process (pr skull)

14
Q

what is the territory for semispinales capitus?

A

cervical 4-6 vert per

15
Q

what is the territory for rotatores thoracis?

A

deepest, thoracic, 1-2 v

16
Q

what is the territory for multifidus?

A

lumbar, 2-4 v per

17
Q

levator costurum o i

A

transverse process to inferior rib turburcle

18
Q

which transversospinale has a different action and what is it?

A

semispinalis, extension of neck, ipsi rotation

19
Q

what is the action of levator costurum, and where can you find them?

A

elevate ribs, cii-t7

20
Q

what muscles make up the sub occipital triangle?

A

rectus capitus posterior minor, [rcp major], obliquis capitus superior, obliquis capitus inferior dorsal rami of suboccipital nerve– post ramus c1

21
Q

rectus capitus post minor o i

A

post arch of atlas to med aspect of inferior nuchal line

22
Q

rectus posterior major o i

A

spinous process of c2-lateral aspect of nucal line

23
Q

obliquis capitus superior o i

A

transverse process of atlas - point between sup and inf nuchal line

24
Q

obliquis capitus inferior o i

A

transverse process axis - transverse process atlas

25
Q

where does the posterior ramus of c1 exit, and what is its significance?

A

between base of skull and atlas, and it innervates the sub occipital triangle

26
Q

what blood supply is near the occipital triangle, how is it a concern for manipulations?

A

vertebral artery, wraps around transverse process of c1 before foramen magnum, a translation of c1 could cause stroke.

27
Q

what is the path of the greater occipital nerve?

A

goes through traps, also innervates scalp ie cervicogenic headaches after occipital triangle
