Vertebral Column + Spinal Cord Flashcards
how many sclerotomes contribute to a thoracic vertebra
4
name the structures
- dorsal spinous process
- articular facet
- lateral spinous process
- vertebral body
name the structures
- dorsal spinous process
- articular facet
- lateral spinous process
- vertebral body
what is the purpose of the spinous process
increase surface area for soft tissue attachments
long bones have an “epiphysis” what is the equivalent structure called in a vertebra
end plate
how many joints does the average lumbar vertebra contribute to
6
4 articular facets + 2 intervertebral spaces
what is the significance of these gaps
to allow passage of spinal nerves and blood vessels
what is the function of the vertebral column does the anatomy around the anticlinal vertebra support
facilitates hyperextension of the vertebral column by reducing overcrowding of spinous processes
what level of the verebral column do you find the anticlinal vertebrae
caudal thoracic (T11)
which skeleton is that of the animal with the most flexible spine
left = carnivore
name the yes and no joints
occipital/C1/C2
where are the epaxial muscles
dorsal to the lateral spinous processes
which major muscle groups attach to the ventral surfaces of the lateral transverse processes of the lumbar vertebra
hypaxial muscles
including abdominal muscles
what is the vertebral formula of the horse
C7 T18 L6 S5 Cd variable
what is the vertebral formula of the dog
C7 T13 L7 S3 Cd variable
