What parts of the vertebrae are an attachment for muscles and ligaments?
The Spinous and Transverse Processes
Where is the Anterior Longitudinal Ligament located, what does it do, and where is it thickest and thinnest?
- Located on the anterior surface of the vertebral bodies (running all the way down the spine)
- Prevents excessive Hyperextension
- Thin superiorly and thick inferiorly to fuse with sacrum
What are the main Ligaments of the Spine?
- Anterior Longitudinal Ligament
- Posterior Longitudinal Ligament
- Supraspinal Ligament
- Ligamentum Nuchae
- Interspinous Ligament
- Ligamentum Flavum
- Intertransverse Ligament
Where is the Posterior Longitudinal Ligament located, what does it do, and where is it thickest and thinnest?
- Located on the posterior surface of the vertebral bodies (running all the way down the spine)
- Prevents excessive flexion
- Thick superiorly to help support the skull, and thin inferiorly, which contributes to increased disk injury in lumbar area
Where is the Supraspinal Ligament located?
From C7 to the sacrum, along the tips of the spinous processes
Where does the Interspinous Ligament run?
Between successive spinous processes
What does the Ligamentum Flavum do and where is it located?
- Connects adjacent laminae anteriorly
- Located across the bay from the Posterior Longitudinal Ligament
Where is the Ligamentum Nuchae located and what does it do?
- Located in the cervical spine only
- Takes the place of the Supraspinal and Interspinal Ligaments
Where is the Intertransverse Ligament located?
Between successive transverse processes
What are the Arthrokinematics of the C-Spine?
Rotation and Side Bending to the Same Side
What are the Arthrokinematics of the L-Spine?
Rotation and Side Bending to the Opposite Side
What are the Arthrokinematics of the T-Spine?
Upper act as C-Spine and Lower act as L-Spine
What type of Joints are the Intervertebral Joints
Amphiarthrosis or Cartilaginous Joints
Which vertebrae is the point at which the head can nod yes?
C1 or Atlas
Which vertebrae is the point at which the head can shake no?
C2 or Axis
Which vertbrae is the point at which the C-Spine can side bend?
C7
What is a general term for compression of the neurovascular structures located between the first rib, the clavicle, and anterior and middle scalene muscles?
Thoracic Outlet Syndrome
What is the name for a degenerative disorder of the cervical vertebral structure and function?
Cervical Spondylosis
What is the name for a narrowing of the vertebral canal that houses the spinal cord?
Spinal Stenosis
What is the name for a defect in the pars interarticularis?
Spondylolysis
What is the name for when one vertebrae slips forward in relation to an adjacent vertebrae? Usually in response to a fracture, or giving away, of a defective pars interarticularis.
Spondylolisthesis
What is the name for when the nucleus pulposus bulges through the annulus?
Herniated Disk
What is the name for when a pinched or irritated nerve in the neck causes pain, numbness, or weakness radiating into the chest or arm?
Cervical Radiculopathy
What is the name for a collapse of the anterior (body) portion of the vertebrae due to osteoporosis in the thoracic region?
Compression Fracture
