Answer 5

Semispinalis
Multifidus
Rotators

Question 6

Answer 6

Layer five

Question 7

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

Answer 7

Transverse process origin, spinous process insertion

Question 8

What is the innervation of the semispinalis cervicis

Answer 8

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

Question 9

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

Answer 9

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

Question 10

What is the innervation of the semispinalis capitis

Answer 10

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

Question 11

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

Answer 11

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

Question 12

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

Answer 12

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

Question 13

What Is the innervation of the classic multifidus

Answer 13

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

Question 14

Contraction of multifidus cervicis will result in what movements

Answer 14

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

Question 15

What is the classic origin of rotator longus in what movements

Answer 15

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

Question 16

Rotator muscles are typically identified in what region of the spine

Answer 16

Thoracic region

Question 17

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

Answer 17

Illocostalis lumborum pars lumborum
Longissimus thoracis pars lumborum
Multifidus lumborum

Question 18

Contraction of multifidus lumborum will result in what movements

Answer 18

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

Question 19

What innervated the rotators

Answer 19

Dorsal rami at levels of insertion are believed to do so

Question 20

What is the classic origin of rotator brevis or its homolog

Answer 20

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