The dense, living tissue that makes up the skeleton of humans and vertebrate
animals.
Mature bones are made up of three types of tissue:
compact tissue (the hard outer portion of most bones);
cancellous tissue (spongy tissue inside the bones that contains
bone marrow, which makes blood cells); and subchondral tissue
(smooth bone tissue of the joints).
Cancellous tissue, also known as cancellous bone, spongy bone
or trabecular bone, is characterized by its spongy, porous, honeycomb-like
structure and is typically found at the ends of long bones.
Compact tissue is also known as hard bone, compact bone or
compact cortical bone.
