Flashcards in Final Transverospinalis musculature Deck (20)
1

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

T12

2

what is the innervation of the semispinalis thoracis

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

3

what osseous parts of the vertebral column serve as an orgin to the semispinalis cervicis

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

4

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

as many as nine vertebra

5

Which muscles are identified as transversospinalis muscles

Semispinalis
Multifidus
Rotators

6

Transversospinalis muscles represent what layer of the true back

Layer five

7

Based name of this group what is the origin insertion of the transversospinalis

Transverse process origin, spinous process insertion

8

What is the innervation of the semispinalis cervicis

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

9

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

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

10

What is the innervation of the semispinalis capitis

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

11

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

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

12

Contraction of the classic multifidus will result in what movements of the vertebral column

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

13

What Is the innervation of the classic multifidus

Dorsal rami C3-C8, T1-T12, L1-L5, and S1 spinalis nerves (cords levels C3-C8, T1-T12, L1-L5 and S1)

14

Contraction of multifidus cervicis will result in what movements

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

15

What is the classic origin of rotator longus in what movements

Transverse process from c4 and each lower vertebrae to dorsal surface of sacrum

16

Rotator muscles are typically identified in what region of the spine

Thoracic region

17

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

Illocostalis lumborum pars lumborum
Longissimus thoracis pars lumborum
Multifidus lumborum

18

Contraction of multifidus lumborum will result in what movements

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

19

What innervated the rotators

Dorsal rami at levels of insertion are believed to do so

20

What is the classic origin of rotator brevis or its homolog

transverse processes from C3 and each lower vertebra to the dorsal surface of sacrum (c3-c7, t1-t12, l1-l5, sacrum)
