Organization of Skeleton - The Vertebral Column and Thoracic Cage
| Question | Answer |
|---|---|
| The vertebral column encloses and protects the | Spinal Cord |
| The number of separate bones in the vertebral column of an adult is? | 26 |
| The (BLANK) of the vertebrae support the weight of the head and the trunk. | Bodies |
| The (BLANK) separate adjacent vertebrae, and they soften the forces created by walking. | Intervertebral Disc |
| The pedicles, laminae, and (BLANK) of a vertebra form the vertebral arch | Spinous Process |
| The intervertebral foramina provide passageways for | Spinal Nerves |
| Tranverse foramina of cervical vertebrae serve as passageways for (BLANK) leading to the brain. | Vertebral Arteries |
| The first vertebra is also called the | Atlas |
| The second vertebra is also called the | Axis |
| When the head is moved from side to side, the first vertebra pivots around the (BLANK) of the second vertebra. | Dens |
| The (BLANK) vertebrae have the largest and strongest bodies. | Lumbar |
| The number of vertebrae that fuse to form the sacrum is | 5 |
| The upper, anterior margin of the sacrum that projects forward is called the | Sacral Promontory |
| An opening called the (BLANK) exists at the tip of the sacral canal. | Sacral Hiatus |
| The human skeleton contains a total of (BLANK) pairs of ribs. | 12 |
| The last two pairs of ribs that have no cartilaginous attachments to the sternum are sometimes called (BLANK) ribs. | Floating |
| There are (BLANK) pairs of true ribs. | 7 |
| Costal cartilages are composed of (BLANK) tissue. | Hyaline Cartilage |
| The manubrium articulates with the (BLANK) on its superior border | Clavicles |
| For the cervical vertebra what is the: Vertebra Number, Size, Body,Spinous Process, Transverse Foramina? | 7, Smallest, Smallest, C2-C6 are Forked (bifid), Present |
| For the thoracic vertebra what is the: Vertebra Number, Size, Body, Spinous Process, Transverse Foramina? | 12, Intermediate, Intermediate, Pointed and Angled Downward, Absent |
| For the lumbar vertebra what is the: Vertebra Number, Size, Body, Spinous Process,Transverse Foramina? | 5, Largest, Largest, Short & blunt and nearly Horizontal, Absent |
| The three general functions of the thoracic cage are: | 1 Protects heart, lungs and abdominal organs 2 supports the bones of the shoulder girdle & arms 3 helps with breathing. |
