Bone starts as
Cartilage
Blood vessels penetrate the cartilage…
…and bone cells (osteocytes) begin the process of replacing the cartilage model with actual bone.
- process begins well before you are born and does not finish until puberty ends.
Many bones harden from the center…
outward
Some bones grow in a special growth center called
epiphyseal plate (also known as the growth plate)
growth center lies in the
metaphysis (area between the end of the bone(epiphysis) and the long shaft of the bone (diaphysis) )
Suffix for growth
-physis
The bones in the middle of the skeleton are called the
axial part of your skeleton
skull (cranio) is attached to your
spine
spine is made of many similar bones called
vertebrae that connect together
vertebrae protect
your spinal cord
Spine has 4 sections
- neck section (cervical)
-chest/upper back section (thoracic) - lower back (lumbar and sacral)
Ribs(costo) attach to the
vertebrae of the thoracic section
arms and legs branch off both sides of this central part of the skeleton
vertebrae of thoracic section
your upper arm (brachio) leads to the two bones of your
forearm(radius and ulna)
your upper arm (brachio) leads to the two bones of your forearm(radius and ulna), then to your wrist (carpe)
wrist (carpe)
your upper arm (brachio) leads to the two bones of your forearm(radius and ulna), then to your wrist (carpe), and finally to your
fingers (phalanges).
legs begin with your
thigh bone (femur)
legs begin with your thigh bone (femur), work down to the two
shin bones (tibia and fibula)
legs begin with your thigh bone (femur), work down to the two shin bones (tibia and fibula), move on to your
ankle (tarsal)
legs begin with your thigh bone (femur), work down to the two shin bones (tibia and fibula), move on to your ankle (tarsal), and ultimately reach your
toes (phalanges again like the fingers)
