|
|
What is the action of the levator costae?
|
To elevate ribs and LATERALLY flex
|
|
|
What is the origin of the group to which the longissimus belongs? Its insertion?
|
Longissimus belongs to the erector spinae group, which has its origins around the Posterior iliac crest, dorsal sacrum, lumbar spinous processes, and additional slips along the ribs of the axial skeleton
Its insertion is the cervical transverse process and mastiod process; also the thoracic transverse process and their adjacent ribs |

|
Bi extension of the head/neck
Uni lateral flexion and ipsilateral rotation of the head/neck |
|
|
What is the origin of the transversospinalis group?
|
The origin is the dorsal sacrum, the posterior iliac crest, the CERVICAL and thoracic transverse (coat goes around the cervical part too) processes and lumbar mamillary processes.
|

What are the players of the suboccipital triangle?
|
L and \ make L\
The \ is the Rectus capitis major posteror m, which has an origin on the spinous process of C2 and its insertion on the medial area of the inferior nuchal line The L part are the Obliquus capitis inferior and superior m. The L is made by I and _ the _ part is the obliquus capitis inferior m. and spans from the spinous process of C2 to the transverse process of C1. The I part is the obliquus capitis superior and spans from the transverse process of C1 to the area between the superior and inferior nuchal lines on the occipital bone |
