In anatomy, the anatomist defined the standard position and movement of the bones of the skeletal system by universal anatomical terminologies.
The directional position of the bones of arms and legs is represented by the proximal and distal plane.
The proximal direction represents the bone closest to the point of origin or reference while distal represents the bone closest to the farthest away from the reference. Since the left wrist is farther from the reference or the elbow therefore, it is considered distal to the elbow.
Sea caves is a land form that is formed in a cliff by the action of wave of the ocean or lakes. It is called littoral cave and mainly formed by wave action of a sea which involved the process of mechanical erosion and occur in clogged coast where there is break in the wave or wave action.
