Bones and Cartilage

Spongy bone

• also called cancellous

  or trabecular bone. It is found in the long

  bones and it is surrounded by compact bone.

• Chondrocytes; Chondroblasts

• Isogenous

• Yes

• External ear, Epiglottis

• Provides flexible shape and support of soft tissues

Fibrocartilage

• Type II collagen and large areas of dense connective tissue

• Chondrocytes; Fibroblasts

• Isolated; Isogenous groups arranged axially

• No

• Intervertebral disc, Pubic symphysis

• Provides cushioning, tensile strength and resistance to tearing and compression
