What is the right hemicord at the level of C4 mean?

The right hemicord at the level of C4 refers to the right half of the spinal cord at the cervical vertebra C4. This area is significant because it contains neural pathways and structures that are crucial for motor and sensory functions of the upper body and arms. Damage or injury to this region can lead to deficits on the left side of the body due to the crossing of motor and sensory pathways. Understanding this term is important in the context of neurological assessments and spinal cord injuries.
