| Question | Answer |
|---|---|
| What is a dermatome? | a section of skin intervated by a single nerve |
| what is a myotome? | a group of muscles intervated by a single nerve |
| List parts of the vertebra | Body, Pedical, Lamina, Sup/inf articulating process, transverse process, spinus process, vertebral arch. |
| what makes up the intervertibral arch? | intervertibral notches |
| two ligaments dorsal to the vertibrae | interspinus ligament, supraspinus ligament |
| Pars interarticularis | part of the vertebrae located between the superior and inferior articulating process |
| describe the two longitudinal ligaments of the spine. | anterior ligament widens as it descends posterior ligament does the opposite |
| yellow ligament | ligamentum flavum connects the lamina of adjacent vertibrae |
| tectrial membrain | |
