title: Myofascial trigger point text: work as well. The term "trigger point" was coined in 1942 by Dr. Janet Travell to describe a clinical finding with the following characteristics: Activation of trigger points may be caused by a number of factors, including acute or chronic muscle overload, activation by other trigger points (key/satellite, primary/secondary), disease, psychological distress (via systemic inflammation), homeostatic imbalances, direct trauma to the region, collision trauma (such as a car crash which stresses many muscles and causes instant trigger points) radiculopathy, infections and health issues such as smoking. Trigger points form only in muscles. They form as a local contraction in a title: Trigger (Only Fools and Horses) text: Trigger (Only Fools and Horses) Colin Ball, more commonly known as Trigger, is a fictional character in the popular BBC sitcom "Only Fools and Horses" and its prequel "Rock & Chips". He was played by Roger Lloyd-Pack in "Only Fools and Horses" and Lewis Osbourne in "Rock & Chips". A regular at the Nag's Head pub, and old friend of Del Boy, Trigger is a road sweeper, and also appears to dabble in trading and petty thefts (though this status as a small-time thief is soon phased out of the character's development). He once supplied Del with paint which Del title: Myofascial trigger point text: Myofascial trigger point Myofascial trigger points, also known as trigger points, are described as hyperirritable spots in the fascia surrounding skeletal muscle. They are associated with palpable nodules in taut bands of muscle fibers. They are a topic of ongoing controversy, as there is limited data to inform a scientific understanding of the phenomenon. Accordingly, a formal acceptance of myofascial "knots" as an identifiable source of pain is more common among bodyworkers, physical therapists, chiropractors, and osteopathic practitioners. Nonetheless, the concept of trigger points provides a framework which may be used to help address certain musculoskeletal pain. The trigger point title: Chemoreceptor trigger zone text: Chemoreceptor trigger zone The chemoreceptor trigger zone (CTZ) is an area of the medulla oblongata that receives inputs from blood-borne drugs or hormones, and communicates with other structures in the vomiting center to initiate vomiting. The CTZ is located within the area postrema, which is on the floor of the fourth ventricle and is outside of the blood–brain barrier. It is also part of the vomiting center itself. The neurotransmitters implicated in the control of nausea and vomiting include acetylcholine, dopamine, histamine (H-1 receptor), substance P (NK-1 receptor), and serotonin (5-HT3 receptor). There are also opioid receptors present, which may title: Myofascial trigger point text: tenderness that arises from trigger points, focal points of tenderness, a few millimeters in diameter, found at multiple sites in a muscle and the fascia of muscle tissue. Biopsy tests found that trigger points were hyperirritable and electrically active muscle spindles in general muscle tissue. The misdiagnosis of pain is the most important issue taken up by Travell and Simons. Referred pain from trigger points mimics the symptoms of a very long list of common maladies, but physicians, in weighing all the possible causes for a given condition, rarely consider a myofascial source. The study of trigger points has not
