Five genicular branches of the popliteal artery supply the capsule and ligaments of the knee joint. The genicular arteries are the superior lateral, superior medial, middle, inferior lateral, and inferior medial genicular arteries.

Why are the walls of arteries thicker than those of veins?
Because arteries are moving blood being pumped out by the heart, the walls of arteries are thicker and more elastic than those of veins. This is because the blood in the arteries is passing through with a higher pressure than in veins. The thick, elastic walls of arteries accommodate that pressure.
What is the largest artery in the body?
Arteries come in a variety of sizes. The largest artery of the body is the aorta, which begins at the heart. As they move further from the heart, arteries branch off and become increasingly smaller. The smallest arteries are called arterioles.
