Term | Definition |
Vertebral Column or Spine | extends from the skull which it supports to the pelvis where it transmits the weight of the body to the lower limbs. |
Vertebrae | before birth, the spine consists of 33 separate bones. |
Intervertebral Discs | the individuals are separated by pads of flexible fibrocartilage that cushion the vertebrae and absorb shocks while allowing the spine flexibility. |
Herniated Dicss | drying of the discs, along with a weakening of the ligaments of the vertebral column, predisposes older people. |
Primary Curvatures | spinal curvature in the thoracic and sacral regions |
Secondary Curvatures | they develop some time after birth |
Body or Centrum | disclike, weight-bearing part of the vertebra facing anteriorly in the vertebral column. |
Vertebral Foramen | arch formed from the joining of all posterior extensions. |
Transverse Processes | two lateral projections form the vertebral arch. |
Spinous Pricess | single projection arising form the posterior aspect of the vertabral arch. |
Superior and Inferior Articular Processes | paired projections lateral on the vertebral foreman, allowing a vertebra to form joints with adjacent vertebrae. |
Cervical Vertebrae | form the neck region of the spine. |
Atlas | the superior surfaces of its transverse processes contain large depressions that receive the occipital condyles of the skull. |
Axis | acts as a pivot for the rotation of the atlas above. |
Dens | acts as the pivot point. |
Thoracic Vertebrae | are all typical larger than the cervical vertebrae and are distinguished by the fact that they are the only vertebrae to articulate with the ribs. |
Lumbar Vertebrae | have massive blocklike bodies. |
Sacrum | is formed by the fusion of five vertebrae. |
Coccyx | is formed form the fusion of three to five tiny, irregularly shaped vertebrae. |
