|
|
|
Anterior Longitudinal Ligament
|
- connects anterolateral aspects of vertebral bodies and IV disks from C1 to the sacrum
limits hyperextension of column |
|
|
Posterior longitudinal ligament
|
(weaker/ narrower than anterior):
connects posterior aspects of vertebral bodies and IV disks from C2 to the sacrum (located inside the vertebral canal) Expands superiorly to form the tectorial membrane which passes through the foramen magnum to attach to the occipital bone of the skull limits hyperflexion of column |
|
|
Ligamentum flava
|
connect laminae of adjacent vertebrae thereby limiting hyperflexion
|
|
|
Interspinous ligament
|
connect spinous processes of adjacent vertebrae thereby limiting hyperflexion
|
|
|
Supraspinous ligament
|
connect apices of the spinous processes of adjacent vertebrae (C7 to the sacrum) thereby limiting hyperflexion.
|
|
|
Ligamentum nuchae
|
extends superiorly to external occipital protuberance of the occipital bone (also provides a site for muscle attachment)
|
|
|
Where is the sternal notch?
|
Plane from manubriosternal joint to IV disc T4/T5 marks:
|
|
|
what muscle do you see on thoracic cavity (that surrounded the sternum) when you pull back the chest cage?
