Abstract:
The microvasculature of the rectus abdominis muscle in dogs was observed under scanning electron microscope. The specimens were treated by vascular corrosion east and enzymic digestive methods. Some new results had been obtained.The intramuscular arterioles penetrate the muscular fasciculus with almost right angle. The capillaries go along the myofibers oriented parallel to each other and arrange fascicularly. The morphologically distinct precapillary sphincters are apparent at the original region of the capillaries. There are abundant anastomosing channels between the capillaries which constitute ladder-like microvascular networks encircling the myofibers. Sometimes, the calibre was partial enlarged in the anastomosing channel, which may be beneficial to store of the blood oxygen.The physiological significance of the intramuscular microvasculature was discussed.
