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 longest river in the world is the Nile River, located in Africa. From its source in the country of Burundi to its mouth on the Mediterranean Sea, it extends for 4,145 mileâ¦s (6,670 kilometers). But the world's second longest river, the Amazon (4,007 miles, or 6,451 kilometers), which is located in South America, is really the world's biggest river.
