This figure illustrates bone growth in length at the epiphyseal plate. Zone "D" represents

A) bone tissue of the diaphysis.
B) zone of calcification.
C) zone of hypertrophy.
D) zone of proliferation.
E) zone of resting cartilage.

Epiphyseal Plate

A growth plate found in children and adolescents, located in the metaphysis at the ends of long bones, where bone growth occurs.

Hypertrophy

The enlargement of an organ or tissue from the increase in size of its cells, often in response to physical stress or training.

Calcification

is the accumulation of calcium salts in a body tissue, making that tissue hard and rigid.
