It allows more flexible movement which helps us to breathe with ease.
A bone collar is formed around the hyaline cartilage model. The hyaline cartilage is then caviated within the cartilage model. Next, the periosteal bud is invaded with internal cavities and spongy bone is formed. This is followed by the formation of the medllary cavity as ossification continues. The epihyses are ossificated and when this process is completed, the hyaline cartilage remains only in the epiphyseal plates and articular cartilages.

Hyaline cartilage is a type of tissue found at the ends of some bones.It is an amorphous (chondroitin and glucosamine) matrix that surrounds cells that are called chondrocytes (within lacunae).It acts as a support and as a cushion. It has little blood supply and because of that it heals poorly.
Within the spinal column, each vertebra is an irregular bone with a complex structure comprised of bone and hyaline cartilage. So several vertebrae may share certain characteristics. Vertebrae (OR VERTEBRAS) is the plural form of vertebra.
Cranial bones develop within fibrous membranes. Cranial bone tissues are adapted to support weight and withstand the tension and stress of the skull.
Ossification
Bone starts as cartilage in the fetus. As the fetus takes on the final shape, this cartilage arranges, and enough hardening occurs in the limbs to allow the creature to stand shortly after birth. At that point, all the bones begin to harden, and continues to harden all throughout life. Bones contain a level of cartilage all the way until old age.
epiphyseal plate
Chondrocytes in the lacunae divide and secrete matrix, allowing the cartilage to grow from within.
articular
There are no nociceptive receptors within any of the types of cartilage, but only in adjoining/surrounding perichondrium where such exists.
