VERTEBRAL(RAD.ANAPHY
| Question | Answer |
|---|---|
| forms the central axis of the skeleton | Vertebral Column |
| centered in the midsagittal plan of the posterior part of the trunk | Vertebral Column |
| the small segments of bone of verterbral column is called | Vertebrae |
| vertebral column is consist of | 33 small irregular bones |
| most superior part of vertebral column | cervical vertebrae |
| the succeeding 12 bones lie in the dorsal, or posterior, portion of the thorax | thoracic vertebrae |
| the five vertebrae occupying the region of the loin | lumbar vertebrae |
| the next five vertebrae, located in the pelvic region | sacral vertebrae |
| the terminal vertebrae, also in the pelvic region, vary from three to five in number in the adult | coccygeal vertebrae |
| the 24 vertebral segments in the upper three regions remain distinct throughout life | true or movable vertebrae |
| the pelvic segments in the two lower regions | false or fixed verterbrae |
| sacral segments usually fuse into one bone called | sacrum |
| the coccygeal segments referred to as | coccyx |
| four curves of verterbral column that arch anteriorly and posteriorly from midcoronal plane of the body | cervical, thoracic, lumbar and pelvic curves |
| vertebral curves are discussed in reference to the anatomic position and are referred to as | convex anteriorly or concave anteriorly |
| cervical and lumbar curves which are convex anteriorly are called | lordotic curves |
| thoracic and pelvic curves are concave anteriorly and are called | kyphotic curve |
| the lumbar and pelvic curves join at an obtuse angle termed | lumbosacral angle |
| the thoracic and pelvic curves are called ___ because they are present at birth | primary curves |
| the cervical and lumbar curves are called ___ because they develop after birth | secondary or compensatory curves |
| any abnormal increase in the anterior concavity (or posterior convexitu) of the thoracic curve is termed | kyphosis |
| any abnormal increase in the anterior concavity (or posterior convexitu) of the lumbar or cervical curve is termed | lordosis |
| an abnormal lateral curvature of the spine | scoliosis |
| a typical vertebra is composed of two main parts-an anterior mass of bone called ___ | body |
| posterior ringlike portion | vertebral arch |
| vertebral body and arch enclose a space called | vertebral foramen |
| in the articulared column the vertebral foramina form the | vertebral canal |
