Dwarf

cells dwarfism cartilage occurs

Dwarf, person with an underdeveloped skeleton caused by cartilage cells that fail to grow and divide properly. Chondrodystrophic dwarfism exists when certain cartilage cells are defective. Chromosome-related dwarfism occurs when all of the cells are defective. Hormonal dwarfism occurs when a hormone deficiency interferes with the growth of normal cartilage cells. Nonhormonal dwarfism results when disease or severely impaired nourishment blunts the normal growth of cartilage cells.
