Why Do Heart Attacks Cause *Arm* Pain?

О видео

When the brain receives pain from an internal organ, it often projects the pain in the wrong place because of the way sensory nerve paths converge LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Nerve: a whitish fiber or bundle of fibers that transmits impulses of sensation to the brain or spinal cord, and impulses from these to the muscles and organs. - Nerve impulse: a signal transmitted along a nerve fiber. It consists of a wave of electrical depolarization that reverses the potential difference across the nerve cell membranes. - Referred pain: pain perceived at a location other than the site of the painful stimulus/origin. It is the result of a network of interconnecting sensory nerves that supplies many different tissues. - Sensory cortex: the region of the brain that deals with sensory information.
