Bone Cells
Cells that are the “builders” of bone and form the matrix.
Osteoblasts
Dense, strong bone forming the outer layer of long bones.
compact bone
What is the Haversian canal?
This central structure carries blood vessels and nerves inside each osteon.
What is joint?
where bones meet.
Which animal is known for laughing?
Hyena
Mature cells maintain bone and detect mechanical stress.
osteocytes
Porous bone containing trabeculae and red marrow.
spongy bone
Marrow responsible for hematopoiesis
red bone marrow
These joints allow the greatest mobility but are least stable.
synovial joints
What is the only food that never spoils?
Honey
Cell type is responsible for bone resorption.
osteoclasts
Structural, cylindrical unit of compact bone.
osteon
Marrow is mostly fat and serves as energy storage.
yellow bone marrow
Immovable joint that provides strong protection (ex: skull sutures
synarthrosis
What is the fastest land animal?
Cheetah
Stem-like cells give rise to osteoblasts during growth or healing
osteoprogenitor cells
Concentric rings form the osteon.
lamellae
Cells present in an osteon
Osteocytes
Slightly movable joint like the pubic symphysis.
amphiarthrosis
How many hearts does an octopus have?
3
If these cells become overactive, bones rapidly lose density.
Osteoclast
What is hematopoiesis ? and where does it occur?
The process of producing blood cells, which occurs primarily in the bone marrow.
Why Haversian canals are essential for bone’s status as a living tissue.
because they supply nutrients, remove waste, and allow signaling
Freely movable joint such as the shoulder or hip.
diarthrosis
How many bones are in the adult human body?
