They are not. Motor neurons are actors and end at skeletal muscle. Sensory neurons can be as close as the skin, making it more superficial and vulnerable to sensation.

When a body part is compressed, the pressure on the sensory nerves that carry information about touch, temperature, and pain can cause temporary disruption of their function. This disruption can lead to paresthesia, which is an abnormal sensation like tingling, numbness, or burning. In more severe cases, the compression can cause anesthesia, which is a complete loss of sensation in the affected area.

On the other hand, motor neurons that control voluntary movement are less affected by compression because they are less sensitive to pressure. These neurons are located deeper in the body and are more protected by other tissues like muscle and bone. Additionally, motor neurons do not rely on sensory information to generate movement. Instead, they receive signals from the brain and spinal cord that instruct them to contract or relax muscles.

Therefore, even if the sensory neurons are temporarily affected by compression, the motor neurons can still receive signals from the brain and spinal cord and initiate voluntary movements. However, if the compression is severe or prolonged, it can eventually affect the motor neurons as well, leading to paralysis or weakness.
