Match the type of ossification (Intramembranous vs Endochondral) with its brief
description

Intramembranous Ossification: Ossification that develops from mesenchyme

skeletal system.

Calcitonin encourages calcium deposition from blood into bone, reducing blood calcium levels.

Parathyroid hormone stimulates osteoclasts to resorb bone, increasing blood calcium.

Thyroid hormone influences the basal metabolic rate of bone cells, affecting bone turnover.
