Fetal Bone Formation
-Bone formation (osteogenesis) begins during prenatal development and persists throughout adulthood.
-The bones of infants and children are softer than in adults because it has not yet been ossified
-There are two ways in which osteogenesis occurs: intramembranous ossification and endochondral ossification. Both types form by replacing existing cartilage however differ in the method they go about doing it.

Spine Disorders:
Lordosis
- Lordosis refers to a backward curving of the spine. The normal spine is curved backward at the neck (cervical) and low back (lumbar). When the spine curves too far inward, the condition is called lordosis or swayback.
Kyphosis
- Kyphosis literally means hump-back and is used to describe a condition in which the spine is bent forward
Scoliosis
- Scoliosis literally means crookedness and is used to describe a bending of the spine to the side. There are many causes including deformities present at birth, fractures that occur from trauma or from having osteoporosis, damage from infections in the spine, or abnormal nerves or muscles.
Osteoporosis
- Osteoporosis is a condition in which bones gradually become weak and vulnerable to injury.
