Atlas (C1) vs Median nerve
| Property | Atlas (C1) | Median nerve |
|---|---|---|
| Latin Name | Atlas | Nervus medianus |
| Type | Bone | Nerve |
| Body System | Skeletal | Nervous |
| Body Region | Spine | Forearm |
| Function | The first cervical vertebra that supports the skull. Allows nodding movements (flexion and extension) of the head at the atlanto-occipital joint. | Provides motor innervation to most flexors of the forearm and thenar muscles of the hand. Provides sensory innervation to the lateral palm and palmar surface of the lateral three and … |
| Clinical Significance | Jefferson fractures (burst fractures of the atlas) result from axial loading. Atlanto-occipital dislocation is usually fatal. Congenital anomalies include atlas assimilation (occipitalization). | Carpal tunnel syndrome is compression of the median nerve at the wrist, causing numbness, tingling, and weakness. Anterior interosseous syndrome affects motor function. Pronator teres syndrome compresses the nerve proximally. … |
