Final week Flashcards
What forms the ventral slip of the intertransverse ligament in the lumbar spine?
A membranous partition from the vertebral body covers the intervertebral foramen and extends back to the transverse process to form a ventral slip. It is penetrated by the contents of the intervertebral foramen.
What is name given to the superficial layer of the ligamentum nuchae?
the funicular layer or part
What is the ADI?

What is the ADI of children?
about 4.5 mm
What are the three attachment sites for the accessory ligament of the lateral atlanto-axial joint?
the base of the odontoid process and vertebral body of axis to tubercle for the transverse atlantal ligament of axis
What are the degrees of one side axial rotation facilitated at the atlanto-axial joint?
about 40 degrees one side axial rotation
The occiput-C1-C2 joint joint complex accounts for what percent of all cervical axial rotation?
About 60%
What is the embryonic derivative of the apical ligament of the dens or the apicodental ligament?
The notochord
What are the attachment sites for the anterior atlanto-dental ligament?
The alar ligament and the ipsilateral lateral mass of C1
What are the attachment sites for the superficial layer of the membrana tectoria or tectorial membrane?
the posterior part of the inferior epiphyseal rim and vertebral body of C2 to the capsular ligament of the atlanto-occipital joint and cranial dura of the posterior cranial fossa.

the intra-articular ligament
What is the classification of the sixth through ninth interchondral joints?
Diarthrosis arthrodia
What points on the skull are used to measure skull size?
the nasion, vertex, inion and gnathion
What is unique about the ophthalmic artery and vein?
Unlike other artey-vein combinations they will not share the same opening the ophthalmic artey is in the optic canal, ophthalmic veins are in the superior orbital fissure.
What are the contents of the foramen spinosum?
the nervus spinosus from the mandibular division of the trigeminal nerve and the middle meningeal artery.
What forms the roof of the posterior cranial fossa?
