Final answer:
The five zones interstitial growth referring to the epiphyseal plate include the reserve zone, proliferative zone, maturation and hypertrophy zone, calcification zone, and the zone of ossification. This sequence is where chondrocytes develop and progress from resting to becoming part of the bone structure, contributing to bone elongation.
Step-by-step explanation:
The five zones of interstitial growth within the epiphyseal plate are:
- Reserve (resting) zone
- Proliferative zone
- Zone of maturation and hypertrophy
- Zone of calcification
- Zone of ossification (bone deposition)
These zones represent the sequence of events that cells undergo within the growth plate for the elongation of bones. Beginning with the reserve zone, where chondrocytes rest, to the proliferative zone, where they divide, to the maturation and hypertrophy, where they grow and mature. Following this is the calcification zone where the matrix begins to calcify and the final ossification zone where bone tissue replaces the chondrocytes. This results in the longitudinal growth of bones.
