Axillo-axillary anastomoses refer to the connections between the axillary arteries or their branches on both sides of the body, typically occurring in the region of the axilla (armpit). These anastomoses facilitate collateral circulation, which can be crucial if one of the main blood supplies is compromised. They are formed by branches of the subclavian artery and are important for maintaining blood flow to the upper limb.
The structures found in the vestibular region of the oral cavity include the lips, cheeks, and alveolar mucosa. These structures help in the manipulation of food, speech production, and the overall protection of the oral cavity.
The major regions of collateral circulation in the upper extremity include the axilla, the shoulder joint, and the elbow joint. These areas have an intricate network of arteries and anastomoses that can provide alternative routes for blood flow in case of blockages or occlusions in the main arteries supplying the upper extremity. This collateral circulation is essential for maintaining adequate blood supply to the tissues of the upper limb in case of vascular compromise.
Anastomoses
anastomoses
The plural form for anastomosis is anastomoses.
Anastomoses are connections between blood vessels that provide alternate pathways for blood flow. They play a crucial role in maintaining blood supply to tissues, especially when there is blockage or damage to a blood vessel. Anastomoses help ensure oxygen and nutrients can reach tissues even if there is a disruption in the normal blood flow.
they form alternate pathways for blood to reach a given body region

Arteriovenous anastomoses are mainly found in the skin of mammals, particularly in areas like the fingers, toes, ears, and nose. These specialized structures help regulate blood flow and temperature by shunting blood directly from arteries to veins, bypassing the capillary network.
Yes, anastomoses among coronary arterial branches can provide collateral routes for blood delivery to the heart muscle. If one branch becomes blocked, blood can flow through these connections to ensure the heart muscle still receives adequate blood supply.
It depends on its location ,but generally it is less dangerous than an injured artery ,because usually there are other veins and anastomoses that can take the blood to the heart.
From Wiki:The pericardiacophrenic artery is a long slender branch, that accompanies the phrenic nerve, between the pleura and pericardium, to the diaphragm, to which it is distributed; it anastomoses with the musculophrenic and inferior phrenic arteries.
An anastomoses is a vessel which bypasses two other vessels. This acts as a safety net as it ensures the continuing flow of blood in cases where there may be blockage or damage to the primary vessels.
Collateral circulation provides alternate pathways for blood to reach an organ if the usual route is blocked or restricted. It helps to ensure that vital organs receive adequate blood supply even if there is an obstruction in a blood vessel.
