“…The lumen of an existing capillary enlarges and the wall thickens with the migration of smooth muscle cells surrounding the endothelium. (Clark, 1934b). The finding shown in Figure 8a, b in this study seems to support this view.…”

“…In addition, the AVA development relating to human nasal mucosa (Rosatti, 1954) and human ear (Prichard, 1956) was studied. This development was also studied in the ears of rabbits (Clark, 1934b;Morris, 1984;1986), the skins of chicken (MidtgArd, 1989) and the tongues of kittens (Jasinsky, 1979). However, no AVAs were noted in rabbits under 8 day (Morris, 1984) and in 4-day kittens (Jasinsky, 1979).…”

“…New AVAs also developfrom such pathological states as wounding and vascular neoplasm. Although it is stated that increased blood flow is the main detenninant of formation and maintenance of AVAs in the adult rabbit ear during wound healing (Clark, 1934b;Rosatti, 1956), it is not possible that the increase in blood pressure occurring during development of the rabbit (Mott, 1965) is directly related to the increase in the AVA number because it has been reported that blood pressure reaches its highest point in rabbits approximately in 8 weeks while the AVA number continues to increase until the ears reach their maximum length in rabbits approximately in 16 weeks. For this reason, it has also been stated that metabolic factors should be taken into consideration to maintain AVA density (Morris, 1984).…”

Summary: In this study carried out on the development of arteriovenous anastomoses (AVAs) in Rattus norvegicus species, the fetus was followed up 10 days after post coitum (pc). The sections obtained from the fetuses of 10-20-day rats were subjected to the usual processes for examination under the light microscope. Various staining processes were applied on the preparations and the simple and glomus types of AVAs determined in the mesenchyme of fetuses observed to birth every day. The regions with AVAs were then photographed by photomicroscopy and evaluated. From the 10-day embryo to birth, an increase in the smooth muscles in the wall structure of simple anastomoses was observed. It was however very difficult to follow up this increase in glomus anastomoses because the wall structure is more complicated. Their morphology was examined and compared with that in literature.

“…This interpretation is consistent with the findings of Clark & Clark (1934) and of Clark (1938). They observed rhythmical contraction and dilatation in the blood vessels of the intact rabbit's ear when the ear was gently warmed: when the ear was chilled, or heated to above 380 C, this vasomotion ceased.…”
