Transverseospinalis musculature Flashcards
Which muscles are identified as transversospinalis muscles
Semispinalis
Multifidis
Rotators
How many vertebrae can be attached to a single segment by transversospinalis muscles
As many as nine vertebrae
What segment will represent the lowest attachment site for the semispinalis thoracis
T12
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
What osseous parts of the vertebral column serve as an origin to the semispinalis capitis
Tranverse tubercles of C7, T1-T6 or T7
Articular process of C4-C6
The semispinalis capitis and spinalis capitis may fuse to form what muscle
Biventer cervicis
What osseous parts of the vertebral column serve as an origin to the classic multifidis
Articular process of C4-C7
Tranverse process of T1-T12
Mammillary processes of L1-L5
Dorsal surface of S1-S4 or S5
Contraction of the classic multifidis will result in what movements
Lateral flexion & rotation of the spine
Maintains the lumbar lordotic curve
Prevents entrapment of zygapophyseal capsular ligament during movement
Contraction of multifidis cervicis will result in what movements
Alters the zygopophyseal 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
Contraction of the multifidis lumborum will result in what movement
Lateral flexion & rotation of the lumbar spine
Maintains the lumbar lordotic curve and prevents entrapment of lumbar zygapophyseal capsular ligament during movement
Which muscles of the spine exhibit a reversal of the expected origin - insertion combination
Iliocostalis lumborum pars lumborum
longissimus thoracic pars lumborum
multifidis lumborum
Rotator muscles are typically identified in what region of the spine
The thoracic region
