Elvis Presley is not a songwriter. He's not a great guitar player. He's not a talented musician at all really. But... he is the innovator of rock n' roll. He is The King. Best songs: Jailhouse Rock; Suspicious Minds; The Wonder of You.
Thermoreceptors: Warm and Cold Fibers. Our ability to detect temperature changes originates from two types of specialized receptors called thermoreceptors. Similar to pain receptors, these link to free nerve endings and are specific for both warm and cold stimuli.
Some pain receptors are selective in their response to stimuli, but most are sensitive to more than one of the following types of excitation: (1) mechanical stress of trauma; (2) extremes of heat and cold; and (3) chemical substances, such as histamine, potassium ions, acids, prostaglandins, bradykinin, and acetylcholine.
