All nerves ultimately connect to the brain. There are basically two major types of nerves: sensory and motor. Sensory nerves send information such as touch, temperature, and pain to the brain and spinal cord.
Definition of tissue plasminogen activator. : a clot-dissolving enzyme with an affinity for fibrin that is produced naturally in blood vessel linings and is used in a genetically engineered form to prevent damage to heart muscle following a heart attack and reduce neurological damage following ischemic stroke âabbreviation TPA.
TPA has to be administered within the first few hours after a stroke begins. The start of a stroke is counted from the time that you first noticed stroke symptoms. After this very short window of a few hours after a stroke starts, you cannot receive TPA because it might cause more harm than good at that point.
