Specifically, sacrococcygeal dysgenesis (defective development) is a dominant trait, while thoracic hemivertebra (chest half-vertebra) of German shorthaired pointers is a recessive trait. Lumbar spinal nerves carry sensory and motor information to the lower body. Cervical vertebral compressive myelopathy (CVCM or CVM) is a developmental defect of the vertebrae in the neck (cervical vertebrae) that causes narrowing of the spaces in the spine.

The lumbar spine comprises the lower end of the spinal column between the last thoracic vertebra (T12) and the first sacral vertebra (S1). Pituitary gland. Severe pain at the site of the fracture is the main symptom of a broken back injury. Each vertebra articulates with its neighbour at five different points: first, at the contact point between the main, central bodies of the bones (centra), which is a ball-and-socket joint; then at two projections (prezygapophyses and postzygapophyses) from the centra, with articulating surfaces that lie above and below; and finally the.
