Antler, a modified form of bone, grows out of the skull bones of certain species of animals, such as deer, and is typically shed once a year.It consists of a thick layer of compact bone, an inner section of spongy bone, and internal blood vessels that are fewer in number and more irregular than the ones present in bone.
Growth occurs at the tip, and is initially cartilage, which is later replaced by bone tissue. Once the antler has achieved its full size, the velvet is lost and the antler's bone dies. This dead bone structure is the mature antler. In most cases, the bone at the base is destroyed by osteoclasts and the antlers fall off at some point. [6]
