| Vomer | Part of boney nasal septum |
| Crista galli | a thin mid-sagittal elevation of the ethmoid bone |
| Vertebral Foramen (Neutral Canal) | AKA neural foramen- is an opening between vertebrae through which spinal nerves leave the spine and extend to other parts of the body. |
| Cervical Vertebrae | C1-C7, permits range of motion in neck, small |
| intervertebral discs | shock absorbing structure between each vertebra |

| Anterior Fontanel | diamond shape soft space btw frontal & parietal bone |
| Nucleus Pulposus | Jelly-like substance inside intervertebral disk |
| Sternum | known as the breast bone; it is composed of three divisions and serves as protection for the heart. |
| Sacrum | five fused bones at base of spinal column. |
| Sacral foramina | four pairs of rounded foramina which allows spinal nerves and sacral vessels to pass through. |
| Coracoid Process | Sup and Ant portion of scapula. muscle attachment point and articulates with humerus and clavical |
| Suprasternal notch | Indentation between the Clavicular notches |
| Scoliosis | Condition in which a person's spine is curved side to side |
| Glenoid Cavity | Articulates with the head of the humerous |
| Lordotic Curve | The normal posterior curve of the cervical and lumbar spine. |
