Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In the which growth zone at the epiphyseal plate are the cells dead and calcified?
A
Zone of resting cartilage
B
Zone of proliferating cartilage
C
Zone of calcified cartilage
D
Ossified bone diaphysis
Explanation: 

Detailed explanation-1: -The zone of calcified matrix, the zone closest to the diaphysis, contains chondrocytes that are dead because the matrix around them has calcified. Capillaries and osteoblasts from the diaphysis penetrate this zone.

Detailed explanation-2: -Zone of Calcified Cartilage: In this area, cartilage is calcified into bone tissue and blood vessels form. This happens at the junction between the epiphysis and diaphysis.

Detailed explanation-3: -Zone of ossification: Osteoblasts deposit bone matrix on the exposed plates of calcified cartilage.

Detailed explanation-4: -proliferation zone, 3. hypertrophic cartilage zone, 4. calcified cartilage zone, and 5. ossification zone.

Detailed explanation-5: -Chondrocytes on the epiphyseal side of the epiphyseal plate divide; one cell remains undifferentiated near the epiphysis, and one cell moves toward the diaphysis. The cells, which are pushed from the epiphysis, mature and are destroyed by calcification.
