The blood flow of the meniscus is from the periphery (outside) to the central meniscus. Blood flow decreases with age and the central meniscus is avascular by adulthood, which slows healing. Menisci show low-intensity on MRI images.
The lateral meniscus (external semilunar fibrocartilage) is a fibrocartilaginous band that spans the lateral side of the interior of the knee joint. It is one of two menisci of the knee, the other being the medial meniscus. It is nearly circular and covers a larger portion of the articular surface than the medial.
Healing of the medial meniscus is generally not possible unless the patient is very young, usually <15 years old. Damage to the outer third of the meniscus has the best healing potential because of the blood supply, but the inner two thirds of the medial meniscus has a limited blood supply and thus limited healing ability.
The menisci are nourished by small blood vessels, but each has a large central section which is avascular and does not get a direct blood supply. This poses a problem in a meniscus injury, as blood flow is diminished and the avascular areas tend to not heal. Injury. The tear of meniscus is among the most common knee injuries. It is usually ...
The systemic circulation is a circuit loop that delivers oxygenated blood from the left heart to the rest of the body through the aorta. Deoxygenated blood is returned in the systemic circulation to the right heart via two large veins, the inferior vena cava and superior vena cava , where it is pumped from the right atrium into the pulmonary ...
Meniscus may refer to: Meniscus (anatomy) , crescent-shaped fibrocartilaginous structure that partly divides a joint cavity Meniscus (liquid) , a curve in the upper surface of liquid contained in an object
Not from the actual human body, of course, but from the anatomical diagrams that purported to represent it. Goss was the esteemed editor of the 25th edition of the seminal classic Gray’s Anatomy . Internationally lauded as the authority on all things anatomical, Gray’s Anatomy had been considered essential for any would-be physician to own ...
One meniscus rests on the medial tibial plateau; this is the medial meniscus. The other meniscus rests on the lateral tibial plateau; this is the lateral meniscus. [3] [4] The menisci are nourished by small blood vessels but have a large area in the center with no direct blood supply (avascular).
