- 1Name the two major parts of an intervertebral discAnnulus Fibrosous & Nucleus pulposus
- 2Discuss what a herniated disc impliesWhen the central nucleus polposus ruptures through the surrounding ring called the annulus fibrosous, commonly referred to as a slipped disc
- 3Anterior longitudinal ligament attaches to...The anterior surface of the vertebral bodies and intervertebral discs of the vertebral column
- 4Posterior longitudinal ligament attaches to...The posterior wall of the vertebral bodies and intervertebral discus, the anterior wall of the vertebral canal
- 5Ligamentum flavum forms part of the ______ wall of the vertebral canalPosterior
- 6Ligamentum Nuchae extends as a boad sheet posteriorly in the midline of the _____Neck
- 7—Were you able to label all the relevant ligaments of the vertebral column in the previous illustration?
- 8Superficial muscles of the backTrapezius, latissimus dorsi, rhomboideus major and minor, levator scapulae
- 9Name the Intermediate muscles of the back and part of their functionSerratus posterior superior located deep to rhomboideus mucles, serratus posterior inferior located deep to latissimus dorsi, all attach to ribs and serve respiratory function
- 10Name the deep muscles of the backErector Spinae muscle group and transversospinalis (most deep) muscle group
- 11Identify the three surface landmarks on the back1) Vertebral prominens (C7) - spinous process
2) Thoracic spinous processes
3) Sacral Triangle - superior angles are the dimples formed over the L&R posterior superior iliac spines, apex is S3 - 12—Identify: Spinal cord, meninges, posterior longitudinal ligament, internal vertebral venous plexus, epidural space, dorsal and ventral horns of spinal cord, denticulate ligament, dura, arachnoid and pia mater, subarachnoid space,
- 13Contents of intervertebral foramen- Parts of spinal nerve
- Spinal (dorsal root) ganglion
- Meninges
- Radicular blood vessels (supply nerve roots)
- Fat - 14Name the structures that are contained within the vertebral canal superior to L1- Spinal cord
- Meninges
- Posterior longitudinal ligament
- Internal vertebral venous plexus
- Epidural fat - 15Name the structures that are contained within the vertebral canal inferior to L2- Cauda equina
- Meninges - filum terminale
- Internal vertebral venous plexus
- Posterior longitudinal ligament
- Epidural fat - 16Name the major contents of the epidural space- Epidural fat
- Internal vertebral venous plexus
- Posterior longitudinal ligament - 17Contrast the location, function and appearance of the anterior and posterior longitudinal ligamentsAnterior - single, broad flat strong ligament; attaches to the anterior surface of the bodies and intervertebral discs
Posterior - Single, narrow band-like ligament; attaches to anterior wall of vertebral canal, lies on the posterior wall of vertebral bodies
Function - both protect intervertebral disc - 18Describe the compostition of the dural/thecal sac. How does the dural sac differ from the caudal sac and lumbar cistern?Dural sac - membranous sac encasing spinal cord within structure of certebral column, contains CSF - refers to the entire dural structure surrounding the spinal cord
Lumbar cistern - is the dilation of the subarachnoid space in the lumbar region
Caudal sac - wall formed by arachnoid and dura mater, contains the cauda equina, filum terminale and CSF - 19Why is posterolateral herniation the most common?This is where the annulus fibrosous is thinner and lacks the structure support from the anterior and posterior longitudinal ligaments - therefore it is more likely to rupture at this point
