CERVICAL JUNCTIONS - Ligaments
Short ligaments:
- Lig. Interspinalia
- Lig. Flava: btw the arches, short, elastic
- Discus intervertebrale
- Annulus Fibrosus
- Nucleus Propulsus
- Lig. Intertransversaria

- Funiculis Nuchea = Lig.Nuchea (stops at C2, in Ca)
- Lig.Supraspinale
- Lig. Longitudinale dorsale
- Lig. Longitudinale Ventrale
IN CA:
Funiculus nucheale
= Lig. Nuchea, stops at C2
IN EQ
Funniculus nucheale
= Lig. Nuchea + lamina nuchea, stops at Os. Occipitale
3* Bursa SUBLIGAMENTOSA
- Nuchealis cranialis
- Nuchealis caudalis
- Subspinalis
CERVICAL JUNCTIONS - Articulations
ARTICULATIO ATLANTOOCCIPITALIS
- Elipsoidea, Simplex, Biaxial
- Ventral/dorsal flexion/extension
- Lig. lateralis, From proc.paracondylaris –> cran atlas
- Membrana atlantooccipitale vento/dors
ARTICULATIO ATLANTOAXIALE
- Trochoidea; simplex; uniaxial
- Rotation along long axis of the DENS.
Lig. Longitudinalis dentis
- Dens –> Arcus ventr C1
Lig. Apicis dentis (Eq, Bo)
- Dens Apex –> Os Occipitalis
Lig. Transversarium atlantis (ca)
- Ventral arches C1
Membrana atlantis dorsalis
THORACIC
Intersp. diff
