S3 Transversospinalis Musculature

Question 1

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

Answer 1

up to 9

Question 2

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

Answer 2

T12

Question 3

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

Answer 3

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

Question 4

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

Answer 4

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

Question 5

The semispinalis capitis and spinalis capitis may fuse for form what muscle?

Answer 5

biventer cervicis

Question 6

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

Answer 6

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

Question 7

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

Answer 7

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

Question 8

Contraction of multifidis cervicis will result in what movements?

Answer 8

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

Question 9

Contraction of multifidis lumborum will result in what movements?

Answer 9

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

Question 10

Which muscles are identified as transversospinalis muscles?

Answer 10

semispinalis, multifidis, and rotators
