Flashcards in Day 8 (pg 172) Deck (24):
What are the attachment sites for the accessory atlanto-axial ligament?
the base of the odontoid process and vertebral body of axis to the tubercle for the transverse atlantal ligament on the lateral mass of C1; a superior continuation may attach on the occipital bone just behind that of the alar ligament
What ligament forms the medial, posterior boundary of the intervertebral foramen at C1/C2?
the posterior atlanto-axial ligament
What are the degrees of movement facilitated at the atlanto- axial joint?
about 20 degrees flexion- extension, 40 degrees one side axial rotation, and 5 degrees of lateral bending
The occiput C1-C2 joint complex accounts for what percent of all cervical axial rotation?
What are the attachment sites for the apical ligament of the dens or apicodental ligament?
the anterior margin of the foramen magnum and the tip of the odontoid process of C2
What is the embryonic derivative of the apical ligament of the dents or the apicodental ligament?
What are the attachment sites for the superficial layer of the membrane tec toria 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
What are the attachment sites for the deep layer of the membrane tec toria or tectorial membrane?
the posterior part of the inferior epiphyseal rim and vertebral body of C2 to the periosteum behind the cruciate ligament attachment site on the anterior rim of the foramen magnum
For the cervical spine below C2, what is the range of motion allowed for each type of joint motion identified?
90 degrees flexion-extension, 50 degrees one side lateral bending and 33 degrees one side axial rotation
What are the locations for the costovertebral joints on the vertebra?
the costocentral joint at the vertebral body and costotransverse joint at the transverse process
Costocentral radiate or stellate ligaments will attach the head of the rib to what structures?
both the vertebral bodies of the costocentral joint and the intervertebral disc for ribs 1-9
An intra-articular ligament will be identified with which ribs?
Which vertebrae will have a synovial plane (diarthrosis arthrodia) costotransverse joint?
At what rib will the superior costotransverse ligament be absent?
the first rib
What ligaments will attach to the neck of the twelfth rib?
the superior costotransverse ligament from T11 and the lumbocostal ligament from L1
What unique ligament is present at the twelfth rib?
the lumbocostal ligament
Which ribs will have an attachment for the inferior costotransverse ligament?
rib 1- rib 11
At what rib will the inferior costotransverse ligament be absent?
the twelfth rib?
What is the name of the space between the transverse process and the neck of the rib?
the costotransverse foramen
Which ligament "fills" the costotransverse ligament?
the inferior costotransverse ligament
At what rib will the lateral costotransverse ligament be absent?
the twelfth rib
Which vertebral couples of the thoracic spine have the greatest motion?
T11/T12 and T12/L1
Which range of motion is greatest for lower thoracic vertebral couples?
