The anchor is often found in burial places of the early Roman Christians. Other substitute symbols in use were the trident and a decussate cross, which looks like the Greek letter chi. The wide-spread symbol for the Crucifixion in those days was a lamb at the foot of the anchor: the lamb representing Christ, and the anchor the cross.
The human ear is one of the more remarkable parts of the human body, not only because of the beauty and unlikelihood of its structure, but also because of its remarkable sensitivity to sounds. From an anatomical point of view, the ear is conventionally and convenÂ­iently divided into three parts: the outer, the middle and the inner ears.
The outer ear consists of the pinna and the ear canal. Since the outer ear is the only visible portion of the ear in most animals, the word ear often refers to the external part alone.[1] The middle ear includes the tympanic cavity and the three ossicles.
