Quadrate Bone
The quadrate bone is a skull bone in most tetrapods, including amphibians, sauropsids (reptiles, birds), and early synapsids. In most tetrapods, the quadrate bone connects to the quadratojugal and squamosal bones in the skull, and forms upper part of the jaw joint. The lower jaw articulates at the articular bone, located at the rear end of the lower jaw. The quadrate bone forms the lower jaw articulation in all classes except mammals. Evolutionarily, it is derived from the hindmost part of the primitive cartilaginous upper jaw. Function in reptiles In certain extinct reptiles, the variation and stability of the morphology of the quadrate bone has helped paleontologists in the species-level taxonomy and identification of mosasaur squamates and spinosaurine dinosaurs. In some lizards and dinosaurs, the quadrate is articulated at both ends and movable. In snakes, the quadrate bone has become elongated and very mobile, and contributes greatly to their ability to swallow very ...

Quadrate Tubercle
The quadrate tubercle is a small tubercle found upon the upper part of the femur. It serves as a point of insertion of the quadratus femoris muscle, along with the intertrochanteric crest and the linea quadrata. Structure The quadrate tubercle is located about the junction of the upper one-third and lower two-thirds, on the intertrochanteric crest The intertrochanteric crest is a prominent bony ridge upon the posterior surface of the femur at the junction of the neck and the shaft of the femur. It extends between the greater trochanter superiorly, and the lesser trochanter inferiorly. Ana .... In a small anatomical study, it was shown that the epiphysial line passes directly through the quadrate tubercle. The quadrate tubercle is the site of insertion of the quadratus femoris muscle. Variation The size of the quadrate tubercle varies. It is not always located on the intertrochanteric crest. Adjacent areas can also be part of the quadrate tubercle, such as the posterior su ...

Quadrate Lobe Of Liver
In human anatomy, the liver is divided grossly into four parts or lobes: the right lobe, the left lobe, the caudate lobe, and the quadrate lobe. Seen from the front – the diaphragmatic surface - the liver is divided into two lobes: the right lobe and the left lobe. Viewed from the underside – the visceral surface, the other two smaller lobes the caudate lobe, and the quadrate lobe are also visible. The two smaller lobes, the caudate lobe and the quadrate lobe, are known as superficial or accessory lobes, and both are located on the underside of the right lobe. The falciform ligament, visible on the front of the liver, makes a superficial division of the right and left lobes of the liver. From the underside, the two additional lobes are located on the right lobe. A line can be imagined running from the left of the vena cava and all the way forward to divide the liver and gallbladder into two halves. This line is called Cantlie's line and is used to mark the division between t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
