notes on erector spinae
the erector spinae m. is separated into 3 columns of muscle: iliocostalis laterally, longissimus in an intermediate position and spinalis medially; each of these columns has multiple named parts
notes on iliocostalis
the most lateral part of the erector spinae; it may be subdivided into lumborum, thoracis and cervicis portions
notes on interspinales
these are small and fairly insignificant muscles
notes on intertransversarii
these are small and fairly insignificant muscles
notes on longissimus
the intermediate part of the erector spinae;it may be subdivided into thoracis, cervicis and capitis portions
notes on multifidus
semispinalis, multifidus and rotatores make up the transversospinal muscle group
notes on obliquus capitis inferior
greater occipital nerve (DPR of C2) passes superiorly around the inferior margin of inferior oblique
notes on obliquus capitis superior
the suboccipital triangle is formed by obliquus capitis superior and inferior and rectus capitis posterior major
notes on rectus capitis posterior major
none
notes on rectus capitis posterior minor
rectus capitis posterior minor is deeper and inserts more medial than rectus capitis posterior major
notes on rotatores
semispinalis, multifidus and rotatores make up the transversospinal muscle group
notes on semispinalis
three parts are named based on their insertions: capitis, cervicis and thoracis; semispinalis, multifidus and rotatores make up the transversospinal muscle group
notes on spinalis
most medial part of the erector spinae; may be subdivided into thoracis, cervicis and capitis portions
notes on splenius
splenius means bandage; it gets its name from its broad, flat shape
notes on splenius capitis
named for its shape: splenius means bandage and capitis refers to the insertion of this portion of the muscle
notes on splenius cervicis
named for its shape: splenius means bandage and cervicis refers to the insertion of this portion of the muscle
