What osseous parts of the vertebral column serve as an origin to the iliocostalis lumborum pars lumborum?

Spinous processes of L1-L5

1

What osseous parts of the vertebral column serve as an origin to the iliocostalis thoracis?

None

2

What is the insertion of the iliocostalis thoracis?

Costal angles of the upper 6-7 ribs, transverse process of C7

3

What osseous parts of the vertebral column serve as an origin to the iliocostalis cervicis?

None

4

What osseous parts of the vertebral column serve as an origin to the longissimus thoracis?

Accessory process & transverse process of L1-L5, spinous processes of L3-L5 and median sacral crest S1-S3

5

Which erector spinae muscles attach to cervical articular processes?

Longissimus cervicis & longissimus capitis

6

Which muscles are identified as trsnsversospinalis muscles?

Semispinalis, multifidis mad rotators

7

How many vertebrae can be attached to a single segment by trsnsversospinalis muscles?

As many as nine vertebrae

8

Which segment will represent the lowest attachment site for the semispinalis thoracis?

T12

9

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

Transverse tubercles of T1-T5 or T6 & articular process of C4-C7

10

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

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

11

What osseous parts of the vertebral column serves as an origin to the semispinalis cervicis?

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

12

The biventer cervicis is formed by the fusion of what Muscles?

Semispinalis capitis, and spinalis capitis

13

Which transversospinalis muscles attaches to articular and mammillary processes along the spine?

Multifidis

14

Contraction of the classic multifidis will result in what movements of the vertebral column?

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

15

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

Iliocostalis lumborum pars lumborum, longissimus thoracic pars lumborum and multifidis lumborum

16

Rotator muscles are typically identified in what region of the spine?

The thoracic region

17

Which suboccipital muscle lacks an attachment to the skull?

Obliquus capitis inferior

18

Which nerve will innervated all suboccipital muscles?

The dorsal ramus of C1, the suboccipital nerve

19

What is the proposed function of the suboccipital muscle group?

Postural stabilizers of the atlanto-occipital and atlanto-axial joints

20

Which suboccipital muscles are known to attach to the dura mater?

Rectus capitis posterior major, rectus capitis posterior minor & obliquus capitis inferior

21

At what locations will interspinalis be absent along the spine?

T3-T4 down to T10-T11

22

Based on the density of muscle spindles what is the proposed function of the interspinalis?

Acts as a proprioceptive transducer in conjunction with intertransversarii to coordinate the smooth movement of the spine and to maintain appropriate posture

23

Which muscle group is innervated by both dorsal rami and ventral rami of spinal nerves?

Intertransversarii

24

Based on the density of muscles spindles what is the proposed function of the intransversarii?

Acts as a proprioceptive transducer in conjunction with interspinalis to coordinate the smooth movement of the spine and to maintain appropriate posture
