A free nerve ending (FNE) or bare nerve ending, is an unspecialized, afferent nerve fiber sending its signal to a sensory neuron. Afferent in this case means bringing information from the body's periphery toward the brain. They function as cutaneous nociceptors and are essentially used by vertebrates to detect noxious stimuli that often result ...
Nerve damage can be assessed with pallesthesia. If there is an inability to sense the vibration being applied from the tuning fork, then nerve damage has occurred. A doctor then assesses the damage and places the patient on treatment, which in severe cases may include amputation of a foot or limb.
A nociceptor (from Latin nocere 'to harm or hurt'; lit. ' pain receptor ') is a sensory neuron that responds to damaging or potentially damaging stimuli by sending "possible threat" signals [1] [2] [3] to the spinal cord and the brain.

Laser evoked potentials (LEPs) are measurements of cortical responses using lasers to selectively stimulate thermonociceptors in the skin. Lasers can emit a radiant-heat pulse stimulus to selectively activate A-delta and C free nerve endings. LEP abnormalities may be indicative of neuropathic pain, while a normal LEP is often more ambiguous.
Research also shows that lidocaine can help ease nerve pain in people with conditions like diabetes-related nerve damage, complex regional pain syndrome, cancer, and pain after breast surgery.
Some nociceptors are unspecialized free nerve endings that have their cell bodies outside the spinal column in the dorsal-root ganglia. [3] Others are specialised structures in the skin such as nociceptive schwann cells. [4] Nociceptors are categorized according to the axons which travel from the receptors to the spinal cord or brain. After ...
“The nerve samples are sliced by what’s called an ultra microtome to these very, very minuscule sections, that are then magnified over 1,000 times and counted basically with an automated ...
