adipose tissue and epiphyses
Bone tissue can be either spongey or compact. Compact bone is found on the walls of the shaft of bones while Spongey bone is found at the ends of the bone where joints are made.
epiphyses
The composition of long bones is both spongy and compact bone. the long bone has at both ends a head or knob which is spongy bone (more holes, less sturdy). At the center of the knob or head called the epiphyses where red blood cells are produced. The epiphyses has what is known as an epiphyseal plate or growth plate in a transverse position and is made of cartilage. This plate can be measured in children to determine if hormone treatments are necessary to promote bone growth in children who might otherwise be below average in bone growth or development. The stick or shaft portion of long bones between the two epiphyses is known as the diaphysis. The diaphysis is hollow but its walls are made of compact bone (less holes, sturdier). In the hollow portion or medullary cavity as it's known of the diaphysis of long bones is where yellow marrow sits which can be converted to red marrow when the body has a deficit. Yellow marrow is yellow in color. On the ends of long bones you will find cartilage which serves to protect bones during movement.
Compact bone is dense and solid in appearance and cancellous bone is characterized by open space partially filled with needle-like structures. Compact bone is found in the main shaft of long bones called the diaphysis. Its' function is to provide strong support without cumbersome weight.
The postnatal haemopoesis takes place in the red bone marrow (myeloid tissue) found in spongy bone of the sternum, vertebrae, ribs, claviculae, pelvic bones, flat bones of the skull and proximal epiphyses of some long bones for example humerus and femur.
Spongy bone is the tissue that makes up the interior of bones; compact bone is the tissue that forms the surface of bones. In long bones, spongy bone forms the interior of the epiphyses; the diaphysis (shaft) consists of compact bone surrounding the central marrow cavity. Spongy bone can also be found in the rib slide (21). It contains large marrow spaces defined by shelves and spicules of bone. The inner space is lined by osteoblasts and osteoclasts (called the endosteum). Osteocytes can be seen in layers in adult spongy bone. Outside all of bone, is a connective tissue sheath called the periosteum. It contains inner layers of osteogenic cells that can give rise to osteoblasts and make new bone,.
Compact bone is dense and solid in appearance and cancellous bone is characterized by open space partially filled with needle-like structures. Compact bone is found in the main shaft of long bones called the diaphysis. Its' function is to provide strong support without cumbersome weight.
Bone cells, which are found within the bone tissue, are responsible for the make-up of the skeleton of vertebrates. There are different types of bone tissue in a bone that are made up of different bone cells: there is the compact tissue which is the hard outer part of the bone, the cancellous tissue which is all the spongy tissue inside of the compact tissue, and the subchondral tissue which is the smooth tissue at the end of each bone. Bone cells all work together inside of the bones to help keep up the skeletal system. The bone cells do many things for the skeletal system such as the development of new bones, the maintenance of bones, and the regulation of minerals in the body.
