Long bones elongate when new cartilage, produced in the epiphyseal plate, is pushed to the edge of the epiphysis while older cartilage, located at the diaphysis side of the epiphysis plate, gets converted into bone. Both red and yellow marrow are packed with blood vessels and capillaries to feed the bone. Knobby ends of a long bone are referred to as the epiphyses, and the diaphysis is the shaft or middle section of the long bone. This little known plugin reveals the answer. Sometimes the bone marrow of the diaphysis is primarily involved, and in osteomyelitis it is usually the compact (cortical) bone of the shaft that undergoes necrosis. The swollen rounded ends of the long bone are the epiphyses.

In children, an epiphyseal plate is located between the epiphysis and the metaphysis. Epiphyses contain red bone marrow, which produces blood cells (haemopoiesis). The cortex represents the exterior of the bone and is covered by the periosteum, while the medulla occupies the interior of the bone, with blood and lymphatic vessels running inside it. At the joint, the epiphysis is covered with articular cartilage; below that covering is a zone similar to the epiphyseal plate, known as subchondral bone. When the body has finished growing, the epiphyseal plate ceases to manufacture new cartilage. The epiphysis is a rounded end of long bone that has direct articulation with bone at the joint. The epiphysis is composed of compact or cortical bone on the outside and spongy, or trabecular, bone on the inside. Joints b. Ligaments c. Cartilage d.

It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses. Structurally, the epiphysis and diaphysis are also distinct. Separating them is a part of the bone known as the metaphysis. See illustration. Often they have bits of bone pieces. - Definition & Tears, Grading & Adapting OT Interventions: Methods & Examples, What is a Dermatome? The epiphysis areas are found at the ends of the humerus, while the diaphysis is found in the middle (shaft) area of the long bone. Compact bone is fairly dense, providing strength. When the epiphysis is entirely cartilaginous, it is almost completely protected from injury; traumatic forces tend to fracture the diaphysis or metaphysis, or infrequently, they may disrupt the physis, as is seen in distal humeral physeal separations in infants. The epiphyses (singular: epiphysis) are the rounded portions at the ends of a bone separated from the metaphysis by the physis.The epiphysis contributes to a joint, compared with an apophysis which is a site of tendon or ligament attachment. The epiphysis is the site of bone growth and is also often the place where a tendon anchors onto the long bone. Called also shaft. It is made up of compact bone and encloses a tubular cavity called marrow cavity. For mechanical reasons, and because there is a poorer blood… Once this occurs, the epiphyseal plate disappears and all that is left behind is a small line in the epiphysis area that is henceforth referred to as the epiphyseal line. © copyright 2003-2020 Study.com.
