the cramiun and vertebrae Flashcards
The cranium may be divided into two major areas for study
cranial vault and cranial base
or calvaria, forming the superior, lateral, and
posterior walls of the skull;
cranial vault
forming the bottom skull
cranial base
Internally, the cranial base has three distinct depressions:
the anterior, middle, and posterior cranial fossae
extending from the skull to the pelvis, forms the body’s major axial support.
The vertebral column
truth. The vertebral
column consists of 24 single bones called
vertebrae
the seven bones of the neck are called
cervical vertebrae
the next 12 bone are
thoracic vertebrae
and the 5 supporting the lower back are .
lumbar vertebrae
The vertebrae are separated by pads of fibrocartilage,called — that cushion the vertebrae and absorb shocks.
intervertebral discs,
The — consists of the bony thorax, which is com-
posed of the sternum, ribs, and thoracic vertebrae, plus the cos-
tal cartilages
thoracic cage
Its cone-shaped, cagelike structure protects the organs of the thoracic cavity, including the critically important heart and lungs.
thoracic cage
The— (breastbone), a typical flat bone, is a result
of the fusion of three bones—the manubrium, body, and
xiphoid process.
sternum
The superiormost — looks like the knot of a tie; it
articulates with the clavicle (collarbone) laterally.
manubrium
The —- constructs the inferior end of the sternum and lies at the level of the fifth intercostal space.
