GENERAL HISTOLOGY

Detailed explanation-1: -The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled internally with spongy bone, another type of osseous tissue. Red bone marrow fills the spaces between the spongy bone in some long bones. Each epiphysis meets the diaphysis at the metaphysis.

Detailed explanation-2: -Answer and Explanation: The ends of long bones are the epiphyses. They are covered in a layer of connective tissue called hyaline cartilage.

Detailed explanation-3: -After spongy bone is formed in the diaphysis, osteoclasts break down the newly formed bone to open up the medullary cavity. The cartilage in the epiphyses continues to grow so the developing bone increases in length. Later, usually after birth, secondary ossification centers form in the epiphyses.
