| III. Oculomotor Nerve | one of three nerves that move the eye |
| IV. Trochlear nerve | one of three that move the eye |
| V. Trigeminal Nerve | mastication/chewing |
| VI. Abducent Nerve | one of three that move the eye |
| VII. Facial Nerve | nerve of the face/ expressions , saliva tears , taste sensation |
| VIII. Vestibulocochlear | aprt of the inner ear equilibrum/ hearing |
| IX. glossopharnyngeal | tongue/pharynx taste swallow, saliva secretion |
| X. Vagus Nerve | viscera/organs |
| XI. Accessory nerve | Traps /Scm head movement |
| XII. Hypoglossal Nerve | moving the tongue for speech |
| C1 | no spinous process, vertebral foramen wide transverse processes articulates w/ occipital condyles |
| C2 | Bifid process on the spinous processes dens axis in pivot joint, first disc in between transverse and spinous processes |
| Thoracic | 12- vertebrae T1-T12 ribs attach to transverseprocesses & body of vertbra, ribs attach to facets |
| Lumbar | 5 vertebrae L1-L5 longest, thickest small transverse processes |
| Sacrum | 5 Vertebrae fused into 1 S1-S5 illums and coxals |
| Coccyx | 1 Vertbrae cooccyxgeal |
| adult | extend L1-L2 |
| baby | extend L2-L3 |
| Conus Medullaris | tapering end of spinal cord as high as T12 as low as L3 |
| Cauda equina (horse Tail) | spinal nerve roots that are a bundle |
| Denticulate LIgaments | lateral to spinal cord, guide wire to stablelize spinal cord a pia mater extension |
| Filum Terminate | a pia mater extension direct contact to spinal cord serves as a anchor |
| spinal tap/ lumbar | done below taper end of spinal cord |
| intervertbral foramen | between all vertbrae opening for spinal nerves |
| roots | attach spinal cord and nerves together , very specific either sensory or motor |
| posterior/dorsal spinal cord | sensory root carry info into the spinal cord |
| anterior/ventral spinal cord | carry motor info out of spinal cord |
| spinal nerves | sensory & motor mixed |
| rami | nerve surface from vertebral branches |
| dorsal rami | innervate deep back muscles |
| ventral rami | form a braid of nerves or plexus, there are 4 plexus |
| cervical plexus | neck-spinal nerves c1-c4 |
| brachial plexus | neck C5-C8 & T1 |
| lumbar plexus | L1-L4 |
| Sacral Plexus | L4-S4 |
| Laminar groove | between transverse & spinous processes |
| Laminectomy | remove section of the bone to relieve pressure on spinal cord |
| cervical movement | flexion lateral flexion rotation extension |
| thoracic movements | rotation, lateral flexion |
| lumbar movement | lateral flexion rotation flexion extension |
