From Wikipedia, the free encyclopedia. The soft palate (also known as velum or muscular palate) is, in mammals, the soft tissue constituting the back of the roof of the mouth. The soft palate is distinguished from the hard palate at the front of the mouth in that it does not contain bone.rom Wikipedia, the free encyclopedia.

Proximal: Toward the beginning, the nearer of two (or more) items. For example, the proximal end of the femur is part of the hip joint, and the shoulder is proximal to the elbow.The opposite of proximal is distal.For a more complete listing of terms used in medicine for spatial orientation, please see the entry to  Anatomic Orientation Terms .or example, the proximal end of the femur is part of the hip joint, and the shoulder is proximal to the elbow.

Radius. The radius is the lateral bone. The proximal part of the radius has a disc-like head that articulates with the capitulum of the humerus. The distal end of the radius widens and forms the primary articulation with the proximal carpal bones of the wrist.Because of the proximal articulation, the radius can cross over the front of the ulna when the hand is turned from one side to the other.emur (thigh). The femur is the only bone of the thigh and it is the heaviest and strongest bone in the body. The proximal part of the femur has a ball-like head that fits into the acetabulum of the hip bone.
