Transversospinalis Musculature Flashcards
Which muscles are identified as transversospinalis muscles?
Semispinalis
Multifidus
Rotators
How many vertebrae can be attached to a single segment by transversospinalis muscles?
As many as 9 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 to T6
Articular Processes of C4-C7
What osseous parts of the vertebral column serve as an origin to the semispinalis capitis?
Transverse Tubercles of C7, T1-T6 or T7
Articular Processes of C4-C6
The semispinais capitis and spinals capitis may fuse to form what muscle?
Biventer Cervicis
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
Mammilary Processes of L1-L5
Dorsal Surfaces of S1-S4 or S5
Contraction of the classic multifidus will result in what movements of the vertebral column?
Lateral flexion and rotation of the spine
Maintains the lumbar lordotic curve
Prevent’s entrapment of zygapophyseal ligament during movement
Contraction of the multifidus lumborum will result in what movements?
Lateral flexion and rotation of the lumbar spine
Maintains the lumbar lordotic curve
Prevents entrapment of lumbar zygapophyseal capsular ligament during movement
What muscles of the spine exhibit a reversal of the expected origin-insertion combination?
Iliocostalis lumborum para lumborum
Longissimus thoracic pars lumborum
Multifidus lumborum
Rotator muscles are typically identified in what region of the spine?
Thoracic Region
