What is Sharpe's fibers?

Sharpe's fibers, also known as "Sharpe's granules," are specialized structures found in the nerve endings of certain sensory neurons. They play a role in the transmission of sensory information, particularly in the context of pain and temperature sensation. Named after the British anatomist Sir William Sharpe, these fibers contribute to the complex processes of sensory perception and neural signaling in the body. Their specific functions and mechanisms are still subjects of research in neurobiology.
