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 Zambezi (also spelled Zambeze and Zambesi) is the fourth-longest river in Africa, the longest east flowing river in Africa and the largest flowing into the Indian Ocean from Africa. The area of its basin is 1,390,000 square kilometres (540,000 sq mi), slightly less than half that of the Nile.astward of the source, the watershed between the Congo and Zambezi basins is a well-marked belt of high ground, running nearly east-west and falling abruptly to the north and south. This distinctly cuts off the basin of the Lualaba (the main branch of the upper Congo) from that of the Zambezi.
