What tissue is found in the medullary cavity of a long bone?

Answer 1

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.

Answer 2

A typical long bone contains blood tissue, cancellous bone, compact bone, dense fibrous tissue, and hyaline cartilage.
