STUDIES OF ARTERIAL DISTRIBUTION OF THE M?LATISSIMUS DORSI, GRACILIS, TENSOR FASCIAE LATAE, GASTROCNEMIUS, SOLEUS / 解剖学报

ABSTRACT

The arteries of the M. latissimus dorsi, gracilis, tensor fasciae latae, gastrocncmius and soleus were studied on 100 Chinese cadavers (40 fetus and babies, 60 adults) by dissection and arteriography. The origin, number, diameter and distribution of these arteries were observed, and were investigated quantitatively by means of MAGISCAN-Ⅰ Image Analyser.Based on the studies of the vascular anatomy of muscles. We classified the arterial distribution into three patterns Type Ⅰ The muscle of this group was supplied by one or two main arteries which coursed the entire muscle belly, as in M. tensor fasciae latae, gastrocnemius, soleus. Type Ⅱ The muscle of this group had a segmental supply of several arteries, which is distributed partially in muscle belly, as in M. gracilis, soleus. Type Ⅲ The musele of this group had a combination of both patterns of vascular arrangement, as in M. latissimus dorsi, soleus.The muscles of Type Ⅰ and Type Ⅱ could often be divided into several regions which were based on the distribution of each branch of the artery.
