Capsular Ligament/ Interspinous Ligament/ Ligamentum Nuchae/ Supraspinous Ligament/ Intertransverse Ligament Flashcards
What is the relationship between the capsular ligament and mobility?
the more lax/loose the capsular ligament is, the greater the motion of the joint
What regions of the vertebral column demonstrate the greatest laxity of capsular ligaments?
the cervical and lumbar regions
What is the status of the human interspinous ligament compared with other common ligaments?
they are poorly developedas ligaments although collagen fibers are present
What is the status of the cervical interspinous ligament?
it is lacking, poorly developed, or simply considered the deep anterior part of the ligamentum nuchae
What is now thought to be the major function of the interspinous ligament?
it is more likely a proprioceptive transducer for the spinal reflex
What are the layers of the ligamentum nuchae?
a superficial and depp layer are identified
What is the name given to the superficial layer of the ligamentum nuchae?
the funicular layer or part
What is the name given to the deep layer of the ligamentum nuchae?
the lamellar layer or part
What are the attachment sites for the superficial layer of the ligamentum nuchae?
the external occipital protuberance, external occipital crest, and spinous tubercle of C7
What is the histological make-up of the human ligamentum nuchae?
it is a yellow elastic ligament, but has more collagen fibers than in quadrupeds
What is the termination level inferiorly for the supraspinous ligament according to current literature?
primarily at L4 (73%); between L4 and L5 (5%)
Where is the supraspinous ligament said to be best developed?
in the lumbar spine
What is now thought to be a major function of the supraspinous ligament?
it is a propiceptive transducer for the spinal refelx
Where in the vertebral column is the intertransverse ligament best developed?
in the lumbar spine?
What part of the intertransverse ligament in the lumbar spine covers the intervertebral foramen?
the ventral slip
