|
| I. Olfactory Nerve |
ability to smell |
| II. Optic Nerve |
back of eye occipital lobe for vision |
| 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 |
