bones that are longer than they are wide. They help with movement and support. Example: femur and humerus.

small, cube-shaped bones that provide support and stability. Example: wrist and ankle bones.

thin, flat bones that protect organs and provide places for muscles to attach. Example: skull, ribs, and sternum.

bones with complex or unusual shapes that do not fit into the other bone categories. Example: vertebrae.

the long, main shaft of a long bone.

the rounded ends of a long bone.

a line of bone that marks where the growth plate used to be after a bone stops growing longer.

the area between the diaphysis and epiphysis where bone growth occurs in a growing person.

the hollow space inside the shaft of a long bone that contains bone marrow.

fatty tissue found mainly in the medullary cavity of adult long bones; it stores energy as fat.

a tough layer of connective tissue covering the outside of a bone.

smooth cartilage covering the ends of bones at joints; it reduces friction and cushions movement.

lightweight bone found inside many bones. It has a porous structure that makes bones lighter while still providing strength.

thin, branching pieces of bone that form the framework of spongy bone.

tissue that produces blood cells. It is found inside spaces within spongy bone.

the hard, dense outer layer of bone that provides strength and protection.

the basic structural unit of compact bone. It is made of rings of bone tissue surrounding a central canal.

a central passageway in an osteon that contains blood vessels and nerves.

a mature bone cell that maintains and monitors bone tissue.

a cell that breaks down old or damaged bone.

tiny channels that connect bone cells and allow them to exchange nutrients and waste.

thin layers or rings of bone tissue that surround the Haversian canal.

a thin layer of connective tissue that lines the inside surfaces of bones, including the medullary cavity.

a small space in bone tissue where an osteocyte is located.

tubes that carry blood, oxygen, and nutrients to and from bone tissue.

small branches of arteries that carry blood toward tissues.

small branches of veins that carry blood away from tissues.

Term	Definition
Osteo-	a word part that means bone.
Long Bones	bones that are longer than they are wide. They help with movement and support. Example: femur and humerus.
Short Bones	small, cube-shaped bones that provide support and stability. Example: wrist and ankle bones.
Flat Bones	thin, flat bones that protect organs and provide places for muscles to attach. Example: skull, ribs, and sternum.
Irregular Bones	bones with complex or unusual shapes that do not fit into the other bone categories. Example: vertebrae.
Diaphysis	the long, main shaft of a long bone.
Epiphysis	the rounded ends of a long bone.
Epiphyseal Line	a line of bone that marks where the growth plate used to be after a bone stops growing longer.
Metaphysis	the area between the diaphysis and epiphysis where bone growth occurs in a growing person.
Medullary Cavity	the hollow space inside the shaft of a long bone that contains bone marrow.
Yellow Bone Marrow	fatty tissue found mainly in the medullary cavity of adult long bones; it stores energy as fat.
Periosteum	a tough layer of connective tissue covering the outside of a bone.
Articular Cartilage	smooth cartilage covering the ends of bones at joints; it reduces friction and cushions movement.
Spongy Bone	lightweight bone found inside many bones. It has a porous structure that makes bones lighter while still providing strength.
Trabeculae	thin, branching pieces of bone that form the framework of spongy bone.
Red Bone Marrow	tissue that produces blood cells. It is found inside spaces within spongy bone.
Compact Bone	the hard, dense outer layer of bone that provides strength and protection.
Osteon	the basic structural unit of compact bone. It is made of rings of bone tissue surrounding a central canal.
Haversian Canal	a central passageway in an osteon that contains blood vessels and nerves.
osteocyte	a mature bone cell that maintains and monitors bone tissue.
Osteoblast	a cell that builds new bone.
Osteoclast	a cell that breaks down old or damaged bone.
Canaliculi	tiny channels that connect bone cells and allow them to exchange nutrients and waste.
Lamellae	thin layers or rings of bone tissue that surround the Haversian canal.
Endosteum	a thin layer of connective tissue that lines the inside surfaces of bones, including the medullary cavity.
Lacuna	a small space in bone tissue where an osteocyte is located.
Blood Vessels	tubes that carry blood, oxygen, and nutrients to and from bone tissue.
Arterioles	small branches of arteries that carry blood toward tissues.
Venules	small branches of veins that carry blood away from tissues.
