anastomoses

Examples of anastomoses in the following topics:

• Anastomoses

  • Anastomoses between arteries and anastomoses between veins result in a multitude of arteries and veins serving the same volume of tissue.
  • Such anastomoses occur normally in the body in the circulatory system, serving as backup routes for blood to flow if one link is blocked or otherwise compromised, but may also occur pathologically.
  • Joint anastomoses.
  • Coronary artery anastomoses.
  • Pathological anastomoses result from trauma or disease and are usually referred to as fistulae.

• Blood Flow in the Skin

  • Arteriovenous anastomoses can be found in areas of the body exposed to maximal cooling, such as the hands, feet, nose, lips and ears.
  • The anastomoses connect cutaneous arterioles and venules directly, playing an important role in the reduction of blood flow in a cold environment.

• Nerve and Blood Supply

  • The blood vessels of the synovial membrane terminate around the articular margins in a fringe of looped anastomoses termed the circulus vasculosus (circulus articularis vasculosus).

• Veins of the Abdomen and Pelvis

  • It anastomoses with the inferior epigastric vein at the level of the umbilicus and drains the anterior part of the abdominal wall and some of the diaphragm.

• Blood Vessel Structure

  • The junctions between vessels are called anastomoses.

• Supply of Blood and Nerves to Bone

  • Near the epiphysis, they anastomose with the metaphyseal and epiphyseal arteries.

• Development of the Cardiovascular System

  • The infraorbital and mandibular arise from a common stem, the terminal part of which anastomoses with the external carotid.
