Explanation It has been generally observed that more than one arterial branch supplies blood to most of the organs. The arteries that supply blood to the same territory (or organ) often merge and forminterconnections called arterial anastomoses. These special interconnections aim at providing collateral channels or alternate pathways for the blood to reach a particular region or a part of the body. Similarly, venous anastomoses are formed due to the coming together or merging of the veins...

Question

Chapter 18.5, Problem 7CYU

Summary Introduction

To review:

The blood vessels among arteries and veins that have more anastomoses.

Introduction:

Anastomoses are the special interconnections formed by blood vessels. These are also referred to as the vascular anastomoses. These provide several alternate pathways for the flow of blood to a particular part of the body. In case one branch gets blocked by a clot or cut, a sufficient amount of blood can still reach the destination or target region of the body by following some other route of circulation.

Students have asked these similar questions

If you transplant trunk neural crest into the cranial neural crest region of a developing embryo, will you see the donor tissue form cartilage? Does the neural crest only give rise to two cells in the developing embryo, and is essential for lamprey to develop their jaw structure? Does a multipotent neural crest cell that is receiving Wnt signals become a Chromaffin cell?

Using quail and chick embryos, quail-specific antibody and fluorescent tissue-specific antibodies, design an experiment where you investigate the tissues the cranial neural crest can give rise to. What are four derivatives of the cranial neural crest that you expect to see in the resulting chimeric embryos?

Does the neural crest have to undergo epithelial to mesenchymal transition prior to migration through the developing embryo? Does the neural crest differentiate into different cell types based on their axial position along the anterior and posterior axis?
