Patellar luxation is a disease of joint structure thatâs passed down from affected dogs to their offspring. In some cases, the bone of the upper limb (the femur) may have a very shallow groove so that the kneecap doesnât always rest in place readily. In others, the tendon that attaches the quadriceps is misplaced so that every time this major muscle is flexed the patella moves towards the center of the body (medial patellar luxation or MPL).
Nile is the longest River in Africa and even in the World which flow through 11 African countries (Ethiopia, Eritrea, Sudan, Uganda, Tanzania, Kenya, Rwanda, Burundi, Egypt, Democratic Republic of the Congo, and South Sudan).
The Congo River (also known as the Zaire River) is a river in Africa, and is the deepest river in the world, with measured depths in excess of 230 m (750 ft). It is the second largest river in the world by volume of water discharged, though it has only one-fifth the volume of the worldâs largest river, the Amazon. Additionally, its overall length of 4,700 km (2,920 mi) makes it the ninth longest river. Its drainage basin covers 4,014,500 square kilometres (1,550,000 sq mi).
