Axial Skeleton Flashcards
Whats up with this dog?
Spondylosis Deformans
- Cause: degeneration in older dogs
- Location: lumbar and thoracic region
- Symptom: decreased motion and discomfort
- Treatment:
Whats up with this dog?
Discospondylitis
- Cause: infection of vert and intervert disc
- Location: thoracolumbar and lumbosacral areas
- Symptom: can be localized or spread through blood stream
- Treatment: antibiotics
Atlanto-occipital joint
Atlanto-occipital joint= joint between atlas and occipital condyles
- AKA “yes joint”
- lateral ligament from lat dorsal arch to occipital bone
*** location for joint taps
Atlanto-axial joint
Atlanto-axial joint= joint between atlas and axis
- AKA “no joint”
- apical ligament of dens
- alar ligaments
- transverse atlantal ligament (holds dens to ventral arch)
** Atlanto-axial instability is uncommon and causes abnormal neck movement which compresses spinal cord. PUT THEM IN NECK BRACE HAHAHA
Nuchal Ligament
Nuchal Ligament
- between the parts of the semispinalis
- biventer cervicis
- complexus
- below splineus m.
- NOT PRESENT IN CAT

Happy Tail
Ligaments of Spine
Ligaments of Spine
- Ventral longitudinal
- on ventral surfaces of vertebral bodies
- axis to sacrum
- Dorsal longitudinal
- dorsal surface of vertebral bodies
- dens to caudal vertebrae
- Supraspinous ligament
- attaches spines
- T1-Cd3
intervertebral discs
Intervertebral discs
- Location: between all vert except C1-C2
- Structure:
- Anulus fibrosus- outer ring
- Nucleus pilposus- central
- Function: stress absorber
Clinical- will see degeneration of the annulus fibrosus leads to Intervertebral Disc Disease (IVDD). Common in dwarf breeds like doxin, corgi, bulldog.
Explain this
Intervertebral Disc Disease
Herniated disc
- Chondrodystrophic type happens in young dwarf dogs
- Non-chondrodystrophic type in labs and shepherds
Can lead to calcification of disc= reduced movement
