Study Notes
Vertebral Column of a Rabbit
- A rabbit's vertebral column has 7 cervical vertebrae, 13 thoracic vertebrae, 7 lumbar vertebrae, 4 sacral vertebrae, and 16 caudal vertebrae, totaling 47 vertebrae.
Intervertebral Discs
- Intervertebral discs function as shock absorbers and allow for flexibility in the vertebral column.
Synsacrum
- Birds have a synsacrum, a fused structure similar to the urostyle in tadpoles, formed by the fusion of the last thoracic vertebrae and all lumber, sacral, and a few caudal vertebrae.
- Ostriches also exhibit a synsacrum as part of their skeletal structure.
Cervical Vertebrae in Mammals
- Mammals typically have 7 cervical vertebrae, with exceptions like sloths and manatees.
Intervertebral Disc Composition
- The central part of an intervertebral disc is composed of a gel-like substance called the nucleus pulposus.
Bird Skeleton
- In birds, the synsacrum is fused with the pelvic girdle for support during bipedal locomotion.
- The last 4-5 vertebrae in birds fuse to form the pygostyle.
Coccygeal or Tail Bone
- In apes and humans, the coccygeal or tail bone is formed by the fusion of 3-4 caudal vertebrae.
Urostyle
- In frogs and toads, the terminal vertebrae form the urostyle.
Cervical Vertebrae in Rabbits
- The typical cervical vertebra in a rabbit has a characteristic feature of being very small and light.
Thoracic Vertebrae in Rabbits
- The 7th cervical vertebra in a rabbit has a long neural spine.
- The thoracic vertebrae in a rabbit connect to the ribs via costal facets.
Lumbar Vertebrae in Rabbits
- The lumbar vertebrae in a rabbit are characterized by being large and heavy.
Sacrum in Rabbits
- The sacrum in rabbits is a composite structure formed by the fusion of 4 sacral vertebrae.
