A partial nerve injury may leave the area tingly or incompletely numb. Finally even if the nerve is not cut the swelling and bruising to the tea can affect the nerve as well. Usually we consider sharp penetrating injuries as likely having nerve lacerations when sensation is lost. A hand surgeon can examine the hand and pinpoint the site or extent of nerve injury and recommend ...Read more

Neuropraxia (Definition)

Neuropraxia is defined as a temporary loss of function of the nerve. Some nerves are purely sensory while others carry both sensory and motor fibers. Traumatic contusion injuries to nerves or nerve compressions can cause Neuropraxia. Sensory nerves like sural nerve in the leg or mixed sensory and motor nerves like the median and ulnar nerves in the forearm & hand ...Read more


Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
