1
Q

Which muscles are identified as transversospinalis muscles?

A

semispinalis, multifidis and rotators

2
Q

Transversospinalis muscles represent what layer of the true back?

A

layer five

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 muscles?

A

as many as nine vertebrae

5
Q

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

A

T12

6
Q

What is the innervation of the semispinalis thoracis?

A

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

7
Q

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

A

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

8
Q

What is the innervation of semispinalis cervicis?

A

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

9
Q

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

A

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

10
Q

What is the innervation of semispinalis capitis?

A

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

11
Q

What 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

What transversospinalis muscle attached to articular and mammillary processes along the spine?

A

multifidis

13
Q

What is the 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 cervicis 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

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

A

iliocostalis lumborum pars lumborum, longissimus thoracis pars lumborum and multifidis lumborum
