Question

Quizplus · Accepted Answer

A deafferented limb is one that has lost its sensory input, meaning that it no longer receives information from the nerves that would normally provide touch, pain, pressure, temperature, and other sensations. This can occur as the result of nerve damage or injury to the spinal cord, and can result in a range of symptoms including numbness, tingling, loss of coordination, and difficulty with daily activities. It does not necessarily mean that the limb has lost its motor control, and may not be an amputated limb. Additionally, it is not related to whether an organism uses the limb spontaneously or not.
