Back Superior To C7 - Suboccipital Triangle Flashcards
Rectus Capitis Posterior Major Origin
Spinous process of vertebra C2
Rectus Capitis Posterior Major Insertion
Lateral part of inferior nuchal line of occipital bone
Rectus Capitis Posterior Minor Origin
Posterior tubercle of posterior arch of vertebra C1
Rectus Capitis Posterior Minor Insertion
Medial part of inferior nuchal line of occipital bone
Obliquus Capitis Inferior Origin
Posterior tubercle of posterior arch of vertebra C2
Obliquus Capitis Inferior Insertion
Transverse process of vertebra C1
Obliquus Capitis Superior Origin
Transverse process of vertebra C1
Obliquus Capitis Superior Insertion
Occipital bone between superior and inferior nuchal lines
two things exiting foramen magnum
vertebral artery, CN 11
blank begins at foramen magnum while blank ends
spinal cord, medulla oblongata
part of occipital bone that articulates with atlas
occipital condyles
part of occipital bone anterior to foramen magnum
basilar part
these develop due to stress from muscles pulling over the lifetime on the occipital bone
superior/inferior nuchal lines
accessory veins and the vertebral artery passes through this part of the cervical vertebrae
transverse foramen
levator scapulae attaches to this part of atlas
anterior/posterior tubercles
the suboccipital triangle can extend only the blank
atlantooccipital joint
the muscles that make up the suboccipital triangle
rectus capitis posterior major, obliquus capitis superior, obliquus capitis inferior
this can be found in the middle of the suboccipital triangle
vertebral artery
this nerve innervates all the muscles in the triangle plus the rectus capitis posterior minor
suboccipital nerve
