C is B's exclave, and A's enclave. An exclave is strip of land that belongs to a political entity (like a country or a region) but that is not connected to it by land (islands are not counted). The strip of land is surrounded by other political entities. A good example is Kaliningrad Oblast (the region around the Russian city Kaliningrad).
Group of arteries which are placed relatively close the thighâs inner surface, the groin area is called Femoral artery. The origin of Femoral artery is the inguinal ligament known as Femoral Head and it moves along at a place a bit above the knee. This place is termed as Adductor or hunterâs canal.
Femoral neck is the region connecting the shaft of the thigh bone (femur) to its rounded head, which fits into the hip joint (Picture 1).The femoral neck is potentially weak, because of its relatively smaller cross-sectional area and spongy bone tissue (cancellous bone).It is a part of the weight-bearing axis, which means that the weight of the entire body passes through it. Hence, it is the most frequently injured part of the thigh bone.he femoral neck is potentially weak, because of its relatively smaller cross-sectional area and spongy bone tissue (cancellous bone).
