Muscle Biology of Back Flashcards
origin of rotatores thoracis
transverse process of each thoracic vertebrae
insertion of rotatores thoraces
spinous process of the vertebra above each respectivr thoracic vertebrae
innervation of rotatores thoracis
cervical, thoracic and spinal nerves
action of rotatores thoracis
extend and rotate the vertebral column
blood supply of rotatores thoracis
vertebral artery
occipital artery
what type of muscle is rotatores thoracis longi
intrinsic muscle deep in the back
in the thoracic region 11 on each side of the spine
what type of muscle is multifidus
what is made of
where does it extend from and extend towards
intrinsic muscle behind the rotatores thoracis
made of fasciculi and fill the groove on either side of the spinous process
extends from C2 to sacrum
origin of multifidus
sacrum
posterior superior iliac spine
mamillary processes of lumbar vertebrae
transverse processes of thoracic vertebrae
articular processes of cervical vertebrae (C4-C7)
Insertion of multifidus
spinous process 2-4 vertebrae superior to the origin
innervation of multifidus
posterior branches
action of multifidus
stabilizes vertebrae in local movements of the vertebral column
blood supply of multifidus
cervicis - vertebral artery and occipital artery
Thoracis - posterior intercostal arteries
Lumborum - lumbar arteries, lateral sacral artery
spinalis thoracis is one of what type of muscle and name the other muscles
in upper medial colume of erector spinae
spinalis thoracis
spinalis cervicis
spinalis capitis
origin of spinalis thoracis
spinous process of first 2 lumbar and last 2 thoracic vertebrae
insertion of spinalis thoracis
spinous process of upper thoracic vertebrae
innervation of spinalis thoracis
dorsal rami of upper cervical nerves
actions of spinalis thoracis
extends the spine
blood supply of spinalis thoracis
posterior intercostal arteries
origin of spinalis cervicis
ligamentum nuchae
spinous process of 7th cervical
insertion of spinalis cervicis
spinous process of vertebrae C2-C5
Innervation of spinalis cervicis
dorsal rami of upper cervical nerves
action of spinalis cervicis
extend head
blood supply of spinalis cervicis
posterior intercostal arteries
origin of iliocostalis lumbordum
iliac crest and lateral portion of the common erector spinae tendon
insertion of iliocostalis lumbordum
inferior borders of angles of lower 6/7 ribs
innervation of iliocostalis lumbordum
dorsal rami of spinal nerves
thoracic and upper lumbar nerves
