3. It is surrounded by fibrous membrane called perichondrium.

Answer 2

Cartilage:

• It is a flexible connective tissue.
• It is of four types : Hyaline, White, Yellow, Calcified.

★ Hyaline :

• Matrix is nearly fibre less.
• Pliable.
• Location : Nasal, Septum, Articular, Larynx.

★ White :

• Collagen fibre is more.
• Slightly pliable.
• Location : Pubic symphysis

★ Yellow :

• Elastic fibre is more.
• Pliable.
• Location : Ear pinna

★ Calcified :

Bone:

• Study of bone is called osteology.

• Outer most covering : Periosteum.

• Formation of bone is called ossification.

• Bone forming cells : Osteocytes and osteoblasts.

• Bone destroying cells : osteocasts.
