41. The perforating branches of the internal thoracic artery pierce through the internal intercostal muscles of the superior six intercostal spaces. 42. The intercostal spaces are smooth or crossed bv more or less distinct, incised, sometimes raised, spiral lines. 43. Studies have shown that mice muscle development in the intercostal and paraspinal regions can be delayed by inactivating Myf-5. 44. Deep to these muscles are the osseous portions of the 6th and 7th ribs and the internal and external intercostal muscles. 45. They supply the intercostal muscles and, by branches which perforate the Intercostales externi, the Pectoral muscles and the mamma. 46. The lower intercostal nerves supply the Intercostales and abdominal muscles; the last three send branches to the Serratus posterior inferior. 47. The same team reported the treatment of spinal cord AVMs by percutaneous embolization of an intercostal artery using stainless steel pellets. 48. The technique advises surface stimulation of the intercostal skin while using specific sites of the rectus abdominis muscle for surface recording. 49. A wonderful occasion quickly soured as Lidge exited in the fourth inning with a strained intercostal muscle near his left rib cage. 50. The costal and cervical portions and the periphery of the diaphragmatic portion of the parietal pleurae are innervated by the intercostal nerves.
