1
Q

muscles that are identified as transversospinalis muscles

A

semispinalis
multifidis
rotators

2
Q

transversospinalis muscles represent what layer of the true back

A

layer 5

3
Q

based on the name of this group, what is the origin-insertion of the transversospinalis

A

transverse process origin, spinous process insertion

4
Q

how many vertebrae can be attached to a single segment by transversospinalis muscle

A

as many as 9 vertebrae

5
Q

what segment will represent the lowest attachment site for the semispinalis thoracis

A

T12

6
Q

innervation of the semispinalis thoracis

A

dorsal rami of T1-T6 spinal nerves (cord levels T1-T6)

7
Q

osseous parts of the vertebral column that serve as an origin to the semispinalis cervicis

A

transverse tubercles of T1-T5 or T6 & articular processes of C4-C7

8
Q

innervation of the semispinalis cervicis

A

dorsal rami of C6-C8 spinal nerves (cord levels C6-C8)

9
Q

osseous parts of the vertebral column that serve as an origin to the semispinalis capitis

A

transverse tubercles of C7, T1-T6 or T7 & articular processes of C4-C6

10
Q

innervation of the semispinalis capitis

A

dorsal rami of C1-C6 spinal nerves (cord levels C1-C6)

11
Q

osseous parts of the vertebral column serve as an origin to the classic multifidis

A

articular process of C4-C7, transverse processes of T1-T12, mammillary processes of L1-L5 and the dorsal surface of S1-S4 or S5

12
Q

contraction of the classic multifidis will result in what movements of the vertebral column

A

lateral flexion & rotation of the spine, maintains the lumbar lordotic curve and prevents entrapment of zygapophyseal capsular ligament during movement

13
Q

innervation of the classic multifidis

A

dorsal rami of C3-C8, T1-T12, L1-L5 and S1 spinal nerves (cord levels C3-C8, T1-T12, L1-L5 and S1)

14
Q

contraction of multifidis crevicis will result in what movements

A

alters the zygapophyseal capsular ligament response to load distribution determines the cervical spine response to injury as evidenced by neck pain and is a significant contributor to postural control of the head and neck

15
Q

contraction of multifidis lumborum will result in what movements

A

lateral flexion & rotation of the lumbar spine, maintains the lumbar lordotic curve and prevents entrapment of lumbar zygapophyseal capsular ligament during movement

16
Q

muscles of the spine that exhibit a reversal of the expected origin-insertion combination

A

iliocostalis lumborum pars lumborum, longissimus thoracic pars lumborum and multifidis lumborum

17
Q

rotator muscles are typically identified in what region of the spine

A

the thoracic region

18
Q

what is the classic origin of rotator brevis or its’ homolog

A

transverse process from C3 and each lower vertebrae to the dorsal surface of the sacrum
(C3-7, T1-12, L1-5, sacrum)

19
Q

what is the classic origin of rotator longus or its’ homolog

A

transverse processes from C4 and each lower vertebrae to the dorsal surface of sacrum

20
Q

what innervates the rotators

A

dorsal rami at the levels of insertion are believed to do so
