Site of many congenital or nutritional bone diseases in the growing animal
Open in neonates and growing animals
- Chondrocyte proliferation balances cell maturation and death
Closes and ossifies at maturity
- Regulated by androgens
If growth teporarily stops -> layer of bone seals the growth plate -> moves into metaphysis when growth resumes -> forms Harris lines
