Diverse facial, jaw, and throat muscles are involved in the laugh, including levator labii superioris, risorius, mentalis, depressor anguli oris (the "frown" muscle), orbicularis oris, buccinator, and depressor labii inferioris (Ruch 1993). 2. Laughter may be accompanied by a general lowering of muscle tonus and an increase in bodily relaxation, leading one, e.g., to "collapse in laughter" (see Ruch 1993). 3. In laughing, the abdominal muscles and diaphragm contract in a respiratory "fit," not unlike sneezing or crying. Zygomatic and risorious muscles of the face contract in a grimacing smile; mandibular muscles may rhythmically contract as the lower jaw quivers. In a belly laugh, heartbeat accelerates, blood pressure rises, and vocal cords may uncontrollably vibrate. http://members.aol.com/nonverbal3/laugh.htm Sep 14 06, 7:52 AM

It is likely that 53 (listed) facial muscles play at least some part in the expressions of laughing or smiling, particularly when the expression is exaggerated. The following site lists these 53 facial muscles and their respective functions. The list does not include other laugh muscles within the body. http://www.nurseminerva.co.uk/muscular.htm#q1 Sep 14 06, 1:42 PM
